The communication device includes a housing including a first housing structure, a second housing structure, and a hinge cover positioned between at least a portion of the first housing structure and at least a portion of the second housing structure, a flexible display at least partially received in the housing and including a first portion corresponding to the first housing structure, a second portion corresponding to the second housing structure, and a third portion corresponding to the hinge cover, a hinge structure positioned between the third portion of the flexible display and the hinge cover and connected with the first housing structure and the second housing structure, and at least one sealing member positioned between the third portion of the flexible display and the hinge cover and contacting the hinge cover. ## Claims ### Claim 1 A portable communication device, comprising: a housing including: a first housing structure, a second housing structure rotatable with respect to the first housing structure, and a hinge cover positioned between at least a portion of the first housing structure and at least a portion of the second housing structure; a flexible display at least partially received in the housing, the flexible display including: a first display portion corresponding to the first housing structure, and a second display portion corresponding to the second housing structure; and a hinge structure connected with the first housing structure and the second housing structure, wherein the first housing structure includes: a first housing portion defining a first inner surface configured to surround a first portion of the hinge cover while the housing is unfolded, the first housing portion including a first protrusion at an end of the first housing portion extending substantially perpendicularly from the first housing portion towards the hinge cover, wherein the second housing structure includes: a second housing portion defining a second inner surface configured to surround a second portion of the hinge cover while the housing is unfolded, the second housing portion including a second protrusion at an end of the second housing portion extending substantially perpendicularly from the second housing portion towards the hinge cover, wherein the first inner surface and the second inner surface are configured to surround the hinge cover while the housing is unfolded, wherein the first housing portion is configured to form a first gap between an end of the first protrusion and an outer surface of the hinge cover while the housing is folded, wherein the second housing portion is configured to form a second gap between an end of the second protrusion and the outer surface of the hinge cover while the housing is folded, wherein the first protrusion is substantially perpendicular to the first display portion while the housing is unfolded, and wherein the second protrusion is substantially perpendicular to the second display portion while the housing is unfolded. ### Claim 2 (depends on 1) The portable communication device of claim 1, wherein the hinge cover includes at least one third protrusion configured to be positioned adjacent to the first protrusion to form the first gap in a folded state in which the second housing structure is folded to face the first housing structure. ### Claim 3 (depends on 1) The portable communication device of claim 1, wherein the first protrusion includes at least one of a painted layer, a coated layer, or synthetic resin formed on a surface of the first housing structure. ### Claim 4 (depends on 1) The portable communication device of claim 1, wherein the first gap is smaller than a gap between the outer surface of the hinge cover and the first housing portion. ### Claim 5 (depends on 1) The portable communication device of claim 1, further comprising: a first sealing member disposed on the first inner surface of the first housing structure, and positioned adjacent to the first protrusion, wherein the first sealing member is configured to be in contact with the outer surface of the hinge cover. ### Claim 6 (depends on 5) The portable communication device of claim 5, wherein the first sealing member includes fabric, a lubricative high-polymer material, or a sponge. ### Claim 7 (depends on 1) The portable communication device of claim 1, further comprising: a second sealing member disposed on the second inner surface of the second housing structure, and positioned adjacent to the second protrusion, wherein the second sealing member is configured to be in contact with the outer surface of the hinge cover. ### Claim 8 (depends on 7) The portable communication device of claim 7, wherein the second sealing member includes fabric, a lubricative high-polymer material, or a sponge. ### Claim 9 (depends on 7) The portable communication device of claim 7, wherein the second protrusion is configured to move along the outer surface of the hinge cover during folding operation or unfolding operation of the housing. ### Claim 10 (depends on 1) The portable communication device of claim 1, wherein the second gap is smaller than a gap between the outer surface of the hinge cover and the second housing portion. ### Claim 11 (depends on 1) The portable communication device of claim 1, wherein the first protrusion is configured to move along the outer surface of the hinge cover during folding operation or unfolding operation of the housing.
