Operation pedal device for vehicle

A vehicle operation pedal device employed in a vehicle including a partition wall that partitions a passenger compartment from a portion of a vehicle body forward of the passenger compartment, and a vehicle body structural member disposed behind the partition wall, the vehicle operation pedal device comprising:

• a pedal bracket fixed to the partition wall;
• an operation pedal that includes a pedal arm rotatably supported by the pedal bracket, wherein
• an input shaft of a device to which a depression force of the operation pedal is transmitted is connected to the pedal arm, and
• the operation pedal is configured such that the input shaft is moved in conjunction with rotation of the pedal arm;
• a rotation lever that
• includes a contact portion and a pressing portion,
• is supported by the pedal arm via a rotation shaft, and
• is configured to, by receiving a load greater than or equal to a threshold when the contact portion comes into contact with the vehicle body structural member at a collision of the vehicle, rotate about the rotation shaft such that the pressing portion presses the input shaft in a direction intersecting with an axis of the input shaft;
• and
• a shear portion that is configured to
• fix the rotation lever to the pedal arm when the load applied to the rotation lever from the vehicle body structural member is less than the threshold, and
• cancel the fixation by being broken when the load is greater than or equal to the threshold.
