It is farther from the side 3a of the inverter case 3. Therefore, at the time of a vehicle front collision, the first and second parts 6 and 8 can reliably push the master cylinder 5 away from the inverter case 3 in the vehicle width direction. As a result, contact between the inverter 2 and the master cylinder 5 can be reliably avoided at the time of a vehicle front collision.

According to the vehicle front structure according to the present embodiment, the rigidity of the first component case 7 is lower than the rigidity of each of the brake master cylinder 5 and the second component case 9.

It is located in front of the vehicle and faces the front end portion 12a of the bracket 12. Therefore, at the time of the vehicle front collision, the front brace 13 pushes the front end portion 12a of the bracket 12 that is tilted, so that the bracket 12 is in the tilted posture oriented in the first tilting direction as described above, and the first on the bracket 12 in the tilted posture. And the second parts 6 and 8 can surely push out the master cylinder 5 so as to separate it from the inverter case 3.
