Rearward movement preventing device of pedal device for vehicle

A rearward movement preventing device of a pedal device for vehicle, the pedal device for vehicle comprising:

• a pedal bracket configured to fix to a dash panel on a vehicle front side and include a pair of side plates arranged with a gap in a vehicle width direction;
• an operation pedal configured to pivotally support by a first support shaft arranged in the pair of side plates of the pedal bracket and include a depressing part used for depressing operation toward the vehicle front side;
• an intermediate lever configured to pivotally support around a second support shaft arranged in parallel with the first support shaft with respect to the pedal bracket, the intermediate lever pivots around the second support shaft toward an output direction to displace a prescribed output member toward the vehicle front side;
• and
• a coupling link configured to connect the operation pedal to the intermediate lever and pivot the intermediate lever toward the output direction in conjunction with the depressing operation of the operation pedal;
• wherein
• the rearward movement preventing device prevents the depressing part of the operation pedal from displacing toward a vehicle rear side when the dash panel is displaced toward the vehicle rear side, and wherein
• the pair of side plate of the pedal bracket includes:
• an opening for preventing rearward movement configured to be in a direction of a load acting on the second support shaft at a time of vehicle collision with respect to a shaft hole of the second support shaft;
• and
• a movement allowing part configured to hold the second support shaft into the shaft hole of the second support shaft and allow movement of the second support shaft toward the opening for preventing rearward movement when the load due to the vehicle collision acts.
