<p>A brake pedal apparatus (1) for a vehicle is provided with a pedal bracket (2) having a pivot shaft (4), a pivot bracket (3) having a pedal shaft (6), a pedal arm (8), a slide plate (9) fixed to a body structural member of the vehicle and located between the body structural member and the pedal bracket (2), an impact absorbing section, and a rotational motion assisting section. The impact absorbing section permits relative movement of the pivot bracket (3) and the body structural member in a longitudinal direction of the vehicle when the pedal bracket (2) encounters an external force directed rearward of the vehicle at a level beyond a predetermined load, in such a manner that the pivot bracket (3) disengages from the slide plate (9) to allow the pivot bracket (3) to rotate about the pivot shaft (4) while rotating the pedal shaft (6) therewith rearwardly downward of the vehicle. Also, the rotational motion assisting section is normally held in an inoperative position, and operable to be brought into abutting engagement with at least one of the body structural member and the slide plate (9) to promote rotational movement of the pivot bracket (3) about the pivot shaft caused by the impact absorbing section.</p> |
