5 pages, published by Sanei Shobo).

[0003]

In this type of pedal device, a pair of pedal brackets are installed between the dash lower panel and the steering member, and a pedal rotation shaft is spanned between the pair of pedal brackets. When the dash lower panel is retracted and displaced toward the steering member during a collision, the pedal bracket
Since the pedal rotation shaft falls off due to the fact that it is sandwiched between the dash lower panel and the steering member and buckles to widen the distance between them, the pedal rotation shaft falls off. There is a problem that the dash lower panel is required and the degree of freedom in design is small.

Further, although the pedal bracket is originally required to have a high strength, the steering member must be buckled by being stretched by the steering member at the time of a collision, so that the steering member must have a high bending strength.
