In the transport apparatus, the first position is located in an overlapping region between the first frame and the second frame in a height direction that orthogonally intersects the transport direction and the transverse direction. ## Claims ### Claim 1 A transport apparatus, comprising: a first roller and a second roller that transport a medium by rotating with the medium being nipped therebetween; a first frame that includes a first position and a second position that is different from the first position; a predetermined member that extends in a transverse direction that intersects a transport direction of the medium and is joined to the first frame at the first position; a second frame that is joined to the first frame at the second position; and an urging member that exerts a force on the second frame by urging the first roller toward the second roller, wherein the first position is located in an overlapping region between the first frame and the second frame in a height direction that orthogonally intersects the transport direction and the transverse direction. ### Claim 2 (depends on 1) The transport apparatus according to claim 1, wherein the thickness of the second frame is larger than the thickness of the first frame. ### Claim 3 (depends on 1) The transport apparatus according to claim 1, wherein the second frame is bent toward a region in the transport direction. ### Claim 4 (depends on 1) The transport apparatus according to claim 1, wherein the second frame has an engaging portion that is joined to the first frame at the second position, a main body that receives a force from the urging member, and a connection portion that connects the engaging portion and the main body to each other, and the length of the connection portion in the transverse direction is shorter than the length of the engaging portion in the transverse direction. ### Claim 5 (depends on 1) The transport apparatus according to claim 1, further comprising a third frame that is joined to the first frame, wherein the third frame hooks the urging member. ### Claim 6 (depends on 1) A printing apparatus, comprising: the transport apparatus according to claim 1; a printing section that moves in the transverse direction and performs printing on the medium; and the predetermined member, wherein the predetermined member is a guide shaft that guides the printing section in the transverse direction. ### Claim 7 (depends on 2) A printing apparatus, comprising: the transport apparatus according to claim 2; a printing section that moves in the transverse direction and performs printing on the medium; and the predetermined member, wherein the predetermined member is a guide shaft that guides the printing section in the transverse direction. ### Claim 8 (depends on 3) A printing apparatus, comprising: the transport apparatus according to claim 3; a printing section that moves in the transverse direction and performs printing on the medium; and the predetermined member, wherein the predetermined member is a guide shaft that guides the printing section in the transverse direction. ### Claim 9 (depends on 4) A printing apparatus, comprising: the transport apparatus according to claim 4; a printing section that moves in the transverse direction and performs printing on the medium; and the predetermined member, wherein the predetermined member is a guide shaft that guides the printing section in the transverse direction. ### Claim 10 (depends on 5) A printing apparatus, comprising: the transport apparatus according to claim 5; a printing section that moves in the transverse direction and performs printing on the medium; and the predetermined member, wherein the predetermined member is a guide shaft that guides the printing section in the transverse direction.
