The electronic control unit 3a of the ABS actuator 3 is disposed between the strut tower 8 and at a position separated from the electronic control unit 3a of the ABS actuator 3 in the front-rear direction, and covers the electronic control unit 3a of the ABS actuator 3 from behind to protect it.
The ABS actuator 3 has an upper end disposed at substantially the same height as the upper end portion of the strut tower 8, and an inner side surface of the vehicle is disposed at substantially the same position as the side surface of the strut tower 8. The ABS actuator mounting bracket 12 is fixed to the vehicle body at the mounting arm 12e and the rear end of the inner wall 12c. That is, the ABS actuator 3 is mounted on the vehicle so as to protrude forward with respect to the fixing point of the ABS actuator mounting bracket 12 to the vehicle body.

  Thus, in the present embodiment, the protective cover 12B that covers the electronic control unit 3a of the ABS actuator 3 is provided on the ABS actuator mounting bracket 12. Therefore, when the engine moves rearward due to a vehicle collision, the engine mount 10 Are retracted in the same direction and the impact load is transmitted to the ABS actuator 3 so that the ABS actuator mounting bracket 12 is tilted backward, but the electronic control unit 3a of the ABS actuator 3 moving to the strut tower 8 side is protected. Protected by the cover 12B, the control unit 3a does not directly hit the sharp corners of the strut tower 8 or the like. For this reason, damage to the electronic control unit 3a of the ABS actuator 3 can be prevented with a simple configuration. Here, in the ABS actuator mounting bracket 12 according to the present embodiment, the protective cover 12B has a lower horizontal portion 12f formed with a narrow width and is coupled to the bracket body 12A. When 12g receives an impact load from the rear of the vehicle (from the strut tower 8) toward the electronic control unit 3a, the vertical portion 12g falls to the front of the vehicle (on the electronic control unit 3a side) with a bent portion with the horizontal portion 12f as a fulcrum It is easily deformed and absorbs shock, and by contacting the electronic control unit 3a of the ABS actuator 3 over a wide area, stress concentration is prevented and direct contact with the strut tower 8 is prevented. Effectively protect 3a to prevent its damage.

  In the present embodiment, the protective cover 12B is positioned between the electronic control unit 3a of the ABS actuator 3 and the strut tower 8 and at a position spaced apart from the electronic control unit 3a of the ABS actuator 3 in the front-rear direction. Because of the arrangement, the movable range of the ABS actuator 3 is ensured, and the vibration propagation and contact noise transmitted to the protective cover by the vibration of the ABS actuator 3 can be suppressed.

  Furthermore, in the present embodiment, the protective cover 12B is configured separately from the bracket body 12A, and the lower horizontal portion 12f is coupled to the bracket body 12A. Therefore, the shape of the bracket body 12A is simplified and the productivity is increased. It is done.

  In the present embodiment, the bead 20 formed over the connecting portion between the bead 21 formed on the protective cover 12B and the bracket body 12A of the protective cover 12B, and the reinforcing flange 22 formed on the periphery of the protective cover. Since the rigidity of the protective cover 12B is increased by this, the electronic control unit 3a of the ABS actuator 3 is more effectively protected by the protective cover 12B.
