The frame includes a first routing section and a second routing section in which the first branch cable and the second branch cable are arranged, respectively. The foamed resin material is disposed on an inner side of the skin. The first branch cable and the second branch cable are disposed within the foamed resin material in the first routing section and the second routing section. ## Claims ### Claim 1 An armrest comprising: a cable; a frame including a routing section where the cable is disposed; a skin covering the frame; and foamed resin material that is disposed on an inner side of the skin, wherein the cable is disposed within the foamed resin material in the routing section, the routing section includes a retaining portion that is in contact with the cable to suppress the cable from being released from the routing section before being filled with the foamed resin material, and the routing section has a groove shape and includes a lift-up rib protruding from a bottom wall of the routing section and the lift-up rib extends in a direction crossing an extending direction in which the cable extends. ### Claim 2 (depends on 1) The armrest according to claim 1, wherein the retaining portion sandwiches the cable from two sides with respect to an extending direction in which the cable extends. ### Claim 3 (depends on 1) The armrest according to claim 1, wherein the routing section includes a molding hole in a bottom wall of the routing section and the molding hole is for forming the retaining portion. ### Claim 4 (depends on 1) The armrest according to claim 1, wherein the skin includes a skin hole, and a socket that is connected to the cable is exposed from the skin hole. ### Claim 5 (depends on 4) The armrest according to claim 4, wherein the cable includes cables that are arranged in the frame, and the socket includes sockets that are connected to the respective cables. ### Claim 6 (depends on 4) The armrest according to claim 4, further comprising: a cover attached to a hole edge of the skin hole and including a cover hole corresponding to the skin hole, wherein the socket is exposed from the cover hole, and a portion of the skin adjacent to the hole edge of the skin hole is sandwiched between the cover and the socket. ### Claim 7 An armrest comprising: a cable; a frame including a routing section where the cable is disposed; a skin covering the frame; and foamed resin material that is disposed on an inner side of the skin, wherein the cable is disposed within the foamed resin material in the routing section, the routing section includes a retaining portion that is in contact with the cable to suppress the cable from being released from the routing section before being filled with the foamed resin material, and the routing section has a groove shape and includes a molding hole in a bottom wall of the routing section and the molding hole is for forming the retaining portion. ### Claim 8 (depends on 7) The armrest according to claim 7, wherein the retaining portion sandwiches the cable from two sides with respect to an extending direction in which the cable extends. ### Claim 9 (depends on 7) The armrest according to claim 7, wherein the skin includes a skin hole, and a socket that is connected to the cable is exposed from the skin hole. ### Claim 10 (depends on 9) The armrest according to claim 9, wherein the cable includes cables that are arranged in the frame, and the socket includes sockets that are connected to the respective cables. ### Claim 11 (depends on 9) The armrest according to claim 9, further comprising: a cover attached to a hole edge of the skin hole and including a cover hole corresponding to the skin hole, wherein the socket is exposed from the cover hole, and a portion of the skin adjacent to the hole edge of the skin hole is sandwiched between the cover and the socket. ### Claim 12 An armrest comprising: a cable; a frame including a routing section where the cable is disposed, the routing section including a bottom wall and a side wall; a skin covering the frame; and foamed resin material that is disposed on an inner side of the skin, wherein the cable is disposed within the foamed resin material in the routing section, the routing section has a groove shape and includes a retaining portion in the side wall of the routing section, and the retaining portion is in contact with the cable to suppress the cable from being released from the routing section before being filled with the foamed resin material. ### Claim 13 (depends on 12) The armrest according to claim 12, wherein the retaining portion sandwiches the cable from two sides with respect to an extending direction in which the cable extends. ### Claim 14 (depends on 12) The armrest according to claim 12, wherein the routing section includes a lift-up rib protruding from the bottom wall of the routing section and the lift-up rib extends in a direction crossing an extending direction in which the cable extends. ### Claim 15 (depends on 12) The armrest according to claim 12, wherein the routing section includes a molding hole in the bottom wall of the routing section and the molding hole is for forming the retaining portion. ### Claim 16 (depends on 12) The armrest according to claim 12, wherein the skin includes a skin hole, and a socket that is connected to the cable is exposed from the skin hole. ### Claim 17 (depends on 16) The armrest according to claim 16, wherein the cable includes cables that are arranged in the frame, and the socket includes sockets that are connected to the respective cables. ### Claim 18 (depends on 16) The armrest according to claim 16, further comprising: a cover attached to a hole edge of the skin hole and including a cover hole corresponding to the skin hole, wherein the socket is exposed from the cover hole, and a portion of the skin adjacent to the hole edge of the skin hole is sandwiched between the cover and the socket.
