That is, when removing the seat cushion pressure receiving part 14A from the seat cushion frame 13A, it is not necessary to remove the second wire harness 52 from the seat cushion pressure receiving part 14A. Thereby, a seat 1 can be provided that can reduce the working load when removing the seat cushion pressure receiving part 14A from the seat cushion frame 13A. Also, since the seating sensor 46 is provided in the seat cushion pressure receiving part 14A, the operator can remove the seating sensor 46 from the seat cushion frame 13A together with the seat cushion pressure receiving part 14A.

[0082] The operator can break the band part 74 by pulling the tab 82 of the clip 55. Thereby, the operator can easily remove the first wire harness 51 from the seat cushion frame 13A.

[0083] With the above description of the specific embodiments completed, the present invention can be widely modified and implemented without being limited to the above embodiments. For example, various structures can be applied to the clip 55. As shown in FIG. 5, a slot 85 penetrating in the extending direction of the shaft portion 77 may be formed in the flange portion 78 of the clip 55. The tip of the elastic claw 79 may pass through the slot 85 and protrude toward the main body portion 73 side rather than the flange portion 78. A pair of slots 85 may be provided corresponding to the pair of elastic claws 79. According to this configuration, in a state where the engaging portion 75 of the clip 55 is engaged with the engaging hole 71, the tips of the respective elastic claws 79 pass through the engaging hole 71 and the slot 85 and protrude outward of the flange portion 78. Therefore, the operator can release the engagement state between the pair of elastic claws 79 and the edge of the engaging hole 71 by deforming the tips of the pair of elastic claws 79 toward the shaft portion 77 side, and the engaging portion 75 can be removed from the engaging hole 71. Thereby, the first wire harness 51 can be removed from the front member 22. In this case, the fracture starting point portion 81 and the tab 82 may be omitted.

[0084] In another embodiment, as shown in FIG. 6, a weak portion 87 that breaks due to a torsional load applied to the shaft portion 77 may be provided in the shaft portion 77. In this case, the shaft portion 77 is non-rotatably engaged with the engaging hole 71. For example, the engaging hole 71 may be formed as a square hole or the like, and the shaft portion 77 may be formed as a prism that fits into the engaging hole 71. The weak portion 87 may be a notch, a groove portion, or a through hole formed on the surface of the shaft portion 77. The operator can break the shaft portion 77 at the weak portion 87 by gripping the main body portion 73 of the clip 55 and twisting the main body portion 73 about the axis of the shaft portion 77. Thereby, the operator can remove the first wire harness 51 from the front member 22.

[0085] As shown in FIG. 7, the electric actuator 32 has an electric motor 32A and a speed reducer 32B that reduces the driving force of the electric motor 32A. The yoke 32D of the electric motor 32A is coupled to the case 32C of the speed reducer 32B. The yoke 32D may be fastened to the case 32C by bolts. The rotor of the electric motor 32A is rotatably supported by the case 32C and the yoke 32D. The case 32C is coupled to the inner surface of the left seat back side member 26. A break starting portion 91 is formed in the case 32C. The break starting portion 91 is provided around the coupling portion with the yoke 32D. The break starting portion 91 may be a notch, a groove portion, or a thin wall portion. An operator can break the case 32C at the break starting portion 91 by applying a load to the yoke 32D. Thereby, the yoke 32D can be removed from the case 32C, and the rotor can be recovered. The rotor includes a copper wire that constitutes a coil.

[0086] A tool engaging portion 32F is provided on the yoke 32D. An operator may couple a tool to the tool engaging portion 32F and apply a load to the yoke 32D via the tool. The tool engaging portion 32F may be, for example, a hole into which the tip of a rod-shaped tool such as a driver or a bar can be hooked. Further, the tool engaging portion 32F may have a shaft portion 77 that can be inserted into a hole provided at the tip of the tool.

[0087] As shown in FIG. 8, the electric actuator 32 may be provided on the outer surface of the seat back side member 26. In this case, access to the electric actuator 32 becomes easy, and the disassembly work becomes easy.
