This corrugated tube includes a corrugated tube, a passage maintenance member, and an attachment member. The passage maintenance member is die-molded so as to maintain a shape in which at least a portion is curved in the longitudinal direction, and the transverse cross-section is arc shaped. The passage maintenance member has an opening penetrating to the internal peripheral side and the external peripheral side. The attachment member has an internal peripheral engaging part engaging with an internal peripheral portion of a slit in the corrugated tube, an external peripheral engaging part engaging with an external peripheral portion of the opening in the passage maintenance member, and a connecting part for connecting the internal peripheral engaging part and the external peripheral engaging part while disposed in the slit and the opening. ## Claims ### Claim 1 A corrugated tube with a passage maintaining member, comprising: a corrugated tube having annular convex portions and annular concave portions alternately disposed along a longitudinal direction of the corrugated tube and a slit formed along the longitudinal direction; a die-molded passage maintaining member that maintains a shape at least part of which is curved along the longitudinal direction, the passage maintaining member having an arc-shaped horizontal cross section, an opening that passes through inner and outer circumferential sides of the passage maintaining member and extends along at least part of the longitudinal direction, the passage maintaining member being arranged along an outer circumference of the corrugated tube in a state in which the opening is arranged at an outer circumferential side of the slit; and a mounting member having (i) an inner circumferential-side engaging portion that is configured to engage an inner circumferential-side portion of the slit of the corrugated tube, (ii) an outer circumferential-side engaging portion that is configured to engage an outer circumferential-side portion of the opening of the passage maintaining member, and (iii) a connector that connects the inner and outer circumferential-side engaging portions. ### Claim 2 (depends on 1) The corrugated tube with a passage maintaining member as set forth in claim 1, wherein the mounting member is deformable according to the shape of the passage maintaining member in the longitudinal direction. ### Claim 3 (depends on 1) The corrugated tube with a passage maintaining member as set forth in claim 1, wherein a horizontal cross-sectional shape of the mounting member is constant along the longitudinal direction of the mounting member. ### Claim 4 (depends on 1) The corrugated tube with a passage maintaining member as set forth in claim 1, wherein at least one of the inner and outer circumferential-side engaging portions is intermittently formed along the longitudinal direction of the mounting member. ### Claim 5 (depends on 1) The corrugated tube with a passage maintaining member as set forth in claim 1, wherein the passage maintaining member is divided into two divided parts at the opening. ### Claim 6 (depends on 1) The corrugated tube with a passage maintaining member as set forth in claim 1, wherein the opening in the passage maintaining member does not extend along an entire length of the passage maintaining member so that both side portions of the passage maintaining member remain in a connected state. ### Claim 7 (depends on 1) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 1; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 8 (depends on 2) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 2; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 9 (depends on 3) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 3; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 10 (depends on 4) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 4; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 11 (depends on 5) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 5; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 12 (depends on 6) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 6; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member. ### Claim 13 A corrugated tube with a passage maintaining member, comprising: a corrugated tube including: annular convex portions and annular concave portions alternately disposed along a longitudinal direction of the corrugated tube, and a slit formed along the longitudinal direction of the corrugated tube; a rigid passage maintaining member at least part of which is curved along the longitudinal direction, the passage maintaining member having an arc-shaped horizontal cross section, and an opening that passes through inner and outer circumferential sides of the passage maintaining member and that extends along at least part of the longitudinal direction, the passage maintaining member being arranged along an outer circumference of the corrugated tube in a position in which the opening is arranged at an outer circumferential side of the slit; and a mounting member having (i) an inner circumferential-side engaging portion that engages an inner circumferential-side portion of the slit of the corrugated tube, (ii) an outer circumferential-side engaging portion that engages an outer circumferential-side portion of the opening of the passage maintaining member, and (iii) a connector that inter-connects the inner and outer circumferential-side engaging portions. ### Claim 14 (depends on 13) The corrugated tube with a passage maintaining member as set forth in claim 13, wherein the mounting member is deformable according to the shape of the passage maintaining member in the longitudinal direction. ### Claim 15 (depends on 13) The corrugated tube with a passage maintaining member as set forth in claim 13, wherein a horizontal cross-sectional shape of the mounting member is constant along the longitudinal direction of the mounting member. ### Claim 16 (depends on 13) The corrugated tube with a passage maintaining member as set forth in claim 13, wherein at least one of the inner and outer circumferential-side engaging portions is intermittently formed along the longitudinal direction of the mounting member. ### Claim 17 (depends on 13) The corrugated tube with a passage maintaining member as set forth in claim 13, wherein the passage maintaining member is divided into two divided parts at the opening. ### Claim 18 (depends on 13) The corrugated tube with a passage maintaining member as set forth in claim 13, wherein the opening in the passage maintaining member does not extend along an entire length of the passage maintaining member so that both side portions of the passage maintaining member remain in a connected state. ### Claim 19 (depends on 13) A wire harness comprising: the corrugated tube with a passage maintaining member as set forth in claim 13; and a wire harness main body portion that is provided with at least one wire and is inserted through the corrugated tube that has the passage maintaining member.
