Brake apparatus for vehicle

1. A brake pedal supporting structure for a vehicle, comprising:

a partition panel extending in approximately upward and downward directions;

a pedal box provided on the partition panel;

a brake pedal pivotally supported by the pedal box and having a pad provided at a lower end of the brake pedal;

a steering column supported by a steering support beam and having a steering wheel provided at an upper end of the steering column; and

an electric motor of a power steering apparatus mounted on the steering column below the steering support beam,

wherein the electric motor of the power steering apparatus is arranged at a position where the electric motor makes contact with the brake pedal moving backward for receiving a load from the brake pedal at a time of a front collision of the vehicle,

wherein when the brake pedal moves backward at the time of a front collision of the vehicle, the brake pedal rotates around the electric motor so as to move the pad forward relative to the electric motor, and the steering column rotates around the steering support beam so as to move the steering wheel forward relative to the steering support beam.

2. The brake pedal supporting structure for a vehicle, as claimed in claim 1 , wherein the brake pedal comprises a protrusion portion formed to protrude toward the electric motor.

3. The brake pedal supporting structure for a vehicle, as claimed in claim 2 , wherein the steering support beam comprises a guide member to control upward movement of the pedal box at the time of a front collision of the vehicle.

4. The brake pedal supporting structure for a vehicle, as claimed in claim 3 , further comprising

a pedal bracket provided on the partition panel, to support the pedal box from above by a bolt and having a bolt engaging portion for engaging with the bolt, wherein the bolt engaging portion has a cutout opened approximately rearward.

5. The brake pedal supporting structure for a vehicle, as claimed in claim 4 , wherein the cutout of the bolt engaging portion is formed in the pedal bracket so that the pedal bracket does not interfere with the bolt moving backward at the time of front collision of the vehicle.

6. The brake pedal supporting structure for a vehicle, as claimed in claim 2 , further comprising

a pedal bracket provided on the partition panel, to support the pedal box from above by a bolt and having a bolt engaging portion for engaging with the bolt, wherein the bolt engaging portion has a cutout opened approximately rearward.

7. The brake pedal supporting structure for a vehicle, as claimed in claim 6 , wherein the cutout of the bolt engaging portion is formed in the pedal bracket so that the pedal bracket does not interfere with the bolt moving backward at the time of front collision of the vehicle.

8. The brake pedal supporting structure for a vehicle, as claimed in claim 1 , wherein the steering support beam comprises a guide member to control upward movement of the pedal box at the time of a front collision of the vehicle.

9. The brake pedal supporting structure for a vehicle, as claimed in claim 8 , further comprising

a pedal bracket provided on the partition panel, to support the pedal box from above by a bolt and having a bolt engaging portion for engaging with the bolt, wherein the bolt engaging portion has a cutout opened approximately rearward.

10. The brake pedal supporting structure for a vehicle, as claimed in claim 9 , wherein the cutout of the bolt engaging portion is formed in the pedal bracket so that the pedal bracket does not interfere with the bolt moving backward at the time of front collision of the vehicle.

11. The brake pedal supporting structure for a vehicle, as claimed in claim 1 , further comprising

a pedal bracket provided on the partition panel, to support the pedal box from above by a bolt and having a bolt engaging portion for engaging with the bolt, wherein the bolt engaging portion has a cutout opened approximately rearward.

12. The brake pedal supporting structure for a vehicle, as claimed in claim 11 , wherein the cutout of the bolt engaging portion is formed in the pedal bracket so that the pedal bracket does not interfere with the bolt moving backward at the time of front collision of the vehicle.
