Next, effects of the cable mounting structure for the vehicle 1 according to the present embodiment will be described.
The cable mounting structure of the vehicle 1 of this embodiment includes a clamp 32 provided on the left side surface 25a of the electric device 25 to fix the cables 31a, 31b, and 31c to the left side surface 25a of the electric device 25, and the left side surface of the electric device 25. 25a and a bracket 35 for attaching the clamp 32 to the left side surface 25a of the electric device 25;

The clamp 32 includes a clamp body 33, a front mounting leg 33A provided in the front part of the clamp body 33 and protruding forward from the clamp body 33, and a front mounting leg 33A provided in the rear part of the clamp body 33 and protruding rearward from the clamp body 33. and a front mounting leg 33A.

The bracket 35 includes a fixing portion 35A fixed to the left side surface 25a of the electric device 25, a front mounted portion 35B provided in front of the fixing portion 35A and to which the front mounting leg portion 33A is fixed, and the fixing portion 35A. It has a rear mounted portion 35C which is provided at the rear portion and to which the rear mounting leg portion 33B is fixed.

Thereby, the cables 31 a , 31 b , 31 c can be fixed to the terminals 23 A of the motor control device 23 and the motor 8 , and can be fixed to the left side surface 25 a of the electric device 25 . Therefore, the cables 31a, 31b, and 31c can be suppressed from vibrating due to vibrations or the like that accompany running of the vehicle 1, and the cables 31a, 31b, and 31c can be prevented from coming into contact with the front member 12, the rear member 13, or the electric device 25. can be suppressed.

The front mounting portion 35B and the rear mounting portion 35C protrude outward in the vehicle width direction from the left side surface 25a of the electric device 25 via the stepped portions 35b and 35c with respect to the fixed portion 35A. As a result, the vibration of the electric device 25 can be absorbed by bending the front attachment portion 35B and the rear attachment portion 35C.

Therefore, it is possible to suppress the vibration of the cables 31a, 31b, and 31c due to transmission of vibration from the electric device 25 to the cables 31a, 31b, and 31c, and suppress the generation of noise from the cables 31a, 31b, and 31c.

Further, when the vehicle 1 starts or accelerates, the cables 31a, 31b, and 31c are subjected to rearward force, and when the vehicle 1 is decelerated, the cables 31a, 31b, and 31c are subjected to forward force. At this time, the stress applied to the cables 31a, 31b, and 31c can be absorbed by bending the front attachment portion 35B and the rear attachment portion 35C.

Therefore, it is possible to suppress the cables 31a, 31b, and 31c from swaying in the front-rear direction, and to more effectively suppress the generation of noise from the cables 31a, 31b, and 31c.

Further, according to the cable mounting structure of the vehicle 1 of the present embodiment, the front mounting leg portion 33A and the rear mounting leg portion 33B are separated in the vertical direction, so that the clamp 32 is aligned with the vertical center axis O (see FIG. 5). ) can be prevented from rotating in the vehicle width direction.

Therefore, it is possible to suppress the vibration of the cables 31a, 31b, and 31c in the vehicle width direction about the center axis O in the vertical direction. As a result, noise generation from the cables 31a, 31b, and 31c can be more effectively suppressed.

Further, according to the cable mounting structure for the vehicle 1 of this embodiment, the lower portion of the clamp 32 is formed with the inclined surface 33t that is inclined toward the left side surface 25a of the electric device 25 with respect to the upper portion of the clamp 32. there is

As a result, the portions of the cables 31a, 31b, 31c wired to the lower portion of the clamp 32 are arranged on the left side surface 25a of the electric device 25 with respect to the portions of the cables 31a, 31b, 31c wired to the upper portion of the clamp 32. can get closer. Therefore, stress in the direction of the terminal 23A can be prevented from being applied to the cables 31a, 31b, and 31c.

Further, according to the cable attachment structure of the vehicle 1 of this embodiment, the front attached portion 35B and the rear attached portion 35C are separated in the vertical direction, and the rear attached portion 35C positioned above is fixed. It has an extension portion 35D that extends up to the upper portion of the fixed portion 35A while maintaining a state of protruding from the portion 35A through the stepped portions 35b and 35c.

Thereby, the area of the step portion 35b can be increased to the upper portion of the fixed portion 35A. Therefore, vibration of the cables 31a, 31b, and 31c can be suppressed more effectively.

Further, according to the cable mounting structure of the vehicle 1 of this embodiment, the cables 31a, 31b, 31c are fixed to the motor 8 by the clamps 32, so that the cables 31a, 31b, 31c are connected to the terminals 23A of the motor control device 23. In addition to motor 8 and clamp 32 , clamp 32 can be used to secure motor 8 .

Therefore, the number of fixing points for the cables 31a, 31b, and 31c can be further increased, and vibration of the cables 31a, 31b, and 31c can be suppressed more effectively.

On the other hand, since the cables 31a, 31b, 31c are curved between the terminal 23A of the motor control device 23 and the clamp 32, the cables 31a, 31b, 31c curved between the terminal 23A of the motor control device 23 and the clamp 32 is susceptible to vibration.

On the other hand, since the bracket 35 is positioned between the terminal 23A and the clamp 32 in the vertical direction, the central portion of the cables 31a, 31b, and 31c between the terminal 23A and the clamp 32 is clamped by the clamp 32 to the electric device 25. can be fixed to Therefore, it is possible to more effectively suppress the vibration of the curved cables 31a, 31b, and 31c.

It is located on the front side of the rear end 23r.

As described above, since the front end 23f of the terminal 23A is positioned forward of the front end 33f of the clamp body 33, the portions of the cables 31a, 31b, and 31c above the subframe 11 are positioned with respect to the subframe 11 side. The terminal 23A side is wired in a shape curved forward.

As a result, the portions of the cables 31a, 31b, and 31c above the subframe 11 are subjected to a force to return backward.

On the other hand, in the cable wiring structure of this embodiment, the rear attached portion 35C is located above the front attached portion 35B. Since it is positioned in the rear part of 33 and in the upper part of the clamp main body 33, the force that causes the parts of the cables 31a, 31b, and 31c above the subframe 11 to return rearward can be suppressed.

As a result, a force is applied to the cables 31a, 31b, and 31c to cause the portions of the cables 31a, 31b, and 31c above the subframe 11 to return rearward. Vibration of 31c can be suppressed more effectively.

In this embodiment, the rear attached portion 35C is provided above the front attached portion 35B, but the front attached portion 35B may be provided above the rear attached portion 35C. In this case, the front attachment portion 35B of the bracket 35 is provided above the rear attachment portion 35C.
