Vehicle operation pedal device

A vehicle operation pedal device comprising:

• an operation pedal provided with a boss at an upper end part and further provided with a depressing part at a lower end part, the depressing part to be stepped on to a vehicle front side;
• a pair of upper support members fixed to a first vehicle component member disposed on the vehicle front side relative to the operation pedal and received a load acting on the boss of the operation pedal at a stepping operation at both sides of the operation pedal in a vehicle width direction by stepping on the depressing part of the operation pedal to the vehicle front side at a normal time;
• a pair of lower support members fixed to the first vehicle component member and further fixed to the pair of upper support members at the both sides of the operation pedal in the vehicle width direction, the pair of lower support members configured to be rotatably supported the boss of the operation pedal while receiving the load at the stepping operation at the both sides of the operation pedal in the vehicle width direction and further configured to be a weaker strength than the pair of upper support members;
• an upper center support member laid between upper end parts of the pair of upper support members;
• and
• a support part pivotably supporting a tip part of an operating rod protruded toward a vehicle rear side from the first vehicle component member with respect to the operation pedal between the upper end part and the lower end part of the operation pedal, wherein
• the upper center support member includes a sliding receiving part configured to be faced a sliding surface provided so as to incline toward a vehicle lower side as it goes toward the vehicle rear side in a second vehicle component member disposed on the vehicle rear side relative to the first vehicle component member, and wherein
• the pair of upper support members includes an escape hole for which the boss of the operation pedal is led to the vehicle rear side in response to being guided the sliding receiving part of the upper center support member by sliding on the sliding surface of the second vehicle component member and buckling deformation of the pair of lower support members when the first vehicle component member is displaced toward the vehicle rear side at a time of vehicle collision, and wherein
• the boss of the operation pedal pivots toward the vehicle lower side around the support part while moving to the vehicle rear side when the first vehicle component member is displaced toward the vehicle rear side at the time of vehicle collision.
