Vehicular pedal supporting structure

摘要

A pedal bracket (40) is made of die-cast aluminum, and includes peripheral ribs (86), axial ribs (88), and a crack creation portion (92). If a predetermined high load is applied to a front portion of a vehicle, a rear end side of the pedal bracket (40) is separated from a coupling bracket (72) and slides on a guide face (84A) of a slide guide (84). In this process, the rear end side of the pedal bracket (40) is rotationally displaced, while a crack is created in the crack creation portion (92). The crack grows toward the axial ribs (88) and ruptures the pedal bracket (40). Accordingly, while ensuring that a pedal pad (58) of a brake pedal (10) is displaced substantially forwards with respect to the vehicle, the load input to the side of an instrument panel reinforce (26) can be reduced.
