  Further, in the noise absorber mounting structure 5 of the present embodiment, the wire movement restricting portions 526 to 528 are provided on the outer peripheral surface 52 a of the case 52. Thereby, the movement of the circumferential direction D of the electric wire 43 arranged along the axial direction C on the outer peripheral surface 52a of the case 52 is restricted, and interference with other members is suppressed. Therefore, the noise absorber mounting structure 5 of the present embodiment can suppress the interference of the electric wire 43 with other members, so that the durability can be improved.

  Further, in the noise absorber mounting structure 5 described in the present embodiment, the electric wire movement restriction portion is reinforced to reinforce the third electric wire movement restriction portion 528 between the third electric wire movement restriction portion 528 and the outer peripheral surface 52a of the case 52. Ribs 529, 529 provided. Thus, even if a load is applied to the third electric wire movement restriction portion 528, the third electric wire movement restriction portion 528 further suppresses the movement of the electric wire 43 in the circumferential direction D because the third electric wire movement restriction portion 528 is prevented from breaking. It becomes possible to regulate. Therefore, interference of the electric wire 43 with other members is further suppressed. Therefore, the noise absorber mounting structure 5 of the present embodiment can further prevent the electric wire 43 from interfering with other members.

  Further, in the noise absorber mounting structure 5 of the present embodiment, the first connector 57 and the second connector 34 are disposed on one side of the case 52 in the axial direction C, and the electric wire 43 is disposed on the side of the case 52 from one side. It goes to the other side of the axial direction C along the outer peripheral surface 52a, and is passed through the hollow portion 521 from the other side. Thereby, a longer wire length from the first connector 57 to entering the hollow portion 521 of the magnetic core 51 can be secured longer than in the case where the electric wire 43 is passed through the hollow portion 521 from one side. For this reason, since the insertion / extraction stroke of the first connector 57 corresponding to the longer electric wire length can be sufficiently secured, the first connector 57 and the second connector 34 can be easily connected. Therefore, the noise absorber mounting structure 5 of the present embodiment can improve the workability when connecting the first connector 57 and the second connector 34.

  Further, in the noise absorber mounting structure 5 of the present embodiment, the mounting portion 6 is extended from the covering portion 451 covering the bus bar 45 connected to the power control unit 33, and a housing for housing the power control unit 33. It was attached to the body 10 together with the mounting portion 6. Thus, the mounting operation of the support portion 55 and the mounting operation of the bus bar 45 can be performed at one time. Therefore, the noise absorber mounting structure 5 of the present embodiment can improve the workability of the mounting operation.

  Further, in the noise absorber mounting structure 5 of the present embodiment, the mounting portion 6 is provided in the covering portion 451 that covers the bus bar 45 connected to the power control unit 33 mounted on the vehicle 1. Therefore, the noise absorber mounting structure 5 of the present embodiment can increase the degree of freedom of the layout of the components provided in the vehicle 1.
