In the case where the shape of the pillar fixing portion 30 is determined, the distance between the first body attachment hole 30a and the rectangular plate-like portion 10 is increased as much as possible, so that the pillar fixing portion 30 as a whole can be more stably fixed to the front fender of the vehicle body.
As shown in fig. 1, the profiled plate body 40 may include a rectangular body 401 and side connecting plates 402. A part of one side of the rectangular body 401 is connected to the second side surface 102 of the rectangular plate-like portion 10, the side connection plate 402 is coplanar with the rectangular body 401, the side connection plate 402 is located on the side of the rectangular body 401 away from the rectangular plate-like portion 10 and connected to the rectangular body 401, the accelerator pedal mounting hole 401a is located on the rectangular body 401, and the second body connection hole 402a is located on the side connection plate 402.

The rectangular body 401 may have three accelerator pedal mounting holes 401a, and the three accelerator pedal mounting holes 401a are distributed in an isosceles triangle.
Alternatively, the side connecting plate 402 may be located at an end of one side of the rectangular body 401 away from the rectangular plate-like portion 10, so that the second body attaching hole 402a can be kept at a relatively long distance from the rectangular plate-like portion 10, so that the profiled plate body 40 as a whole can be more stably fixed to the vehicle body.
As shown in fig. 1, a triangular reinforcing plate 50 may be disposed between the shaped plate body 40 and the second side 102 of the rectangular plate-shaped portion 10, the triangular reinforcing plate 50 being coplanar with the shaped plate body 40. By arranging the triangular reinforcing plate 50, the connecting strength between the special-shaped plate body 40 and the rectangular plate-shaped part 10 is increased, the integral strength and rigidity of the pedal base are improved, and the vibration of the pedal is further reduced. Since the triangular reinforcing plate 50 is coplanar with the shaped plate body 40, the vibration of the pedal base in the direction parallel to the shaped plate body 40 can be reduced.
As shown in fig. 3, the bottom surface of the rectangular plate-like portion 10 (i.e., the surface of the rectangular plate-like portion 10 that is away from the brake pedal hinge bracket 20) and the bottom surface of the cylindrical fixing portion 30 (i.e., the surface of the cylindrical fixing portion 30 that is close to the bottom surface of the rectangular plate-like portion 10 in the axial direction of the vacuum booster insertion hole 10 a) are not coplanar, so that the cylindrical fixing portion 30 can be matched with the structure in the vehicle body, facilitating more stable attachment of the cylindrical fixing portion 30 to the dash board of the vehicle.

By arranging the two triangular reinforcing plates 50, the connecting strength of the special-shaped plate body 40 and the rectangular plate-shaped part 10 is further increased, the integral strength and rigidity of the pedal base are further improved, and the vibration of the pedal is reduced. Because the two triangular reinforcing plates 50 are coplanar with the special-shaped plate body 40, the vibration of the pedal base in the direction parallel to the special-shaped plate body 40 can be further reduced.
