Claims5
A brake pedal structure for a vehicle comprising:
- a pedal bracket provided on a vehicle dash panel;
- a pedal shaft provided on said pedal bracket;
- a pedal arm pivotally supported by said pedal shaft in a freely rotatable manner around said pedal shaft as a rotational axis;
- and
- a push rod connected to said pedal arm to operate a brake system in response to rotation of said pedal arm in a normal state, said push rod including an interruption portion to interrupt a transmission of a load input at the time of a front-end collision;
- wherein said pedal arm includes an application portion to apply action to said push rod such that said interruption portion interrupts said transmission of said load input at the time of collision, as said application portion is rotating together with said pedal arm as a unit, and
- wherein said push rod is connected to said pedal arm, and said pedal arm has a projection as said application portion, said projection of said pedal arm being positioned apart from said push rod in said normal state and being positioned to come into contact with said push rod in such a manner that said projection pushes said push rod downwardly at the time of a front-end collision.
