It is an object to improve the detection accuracy and durability in detecting a depression force on the basis of a deformation of a sensor member arranged between a pedal arm and an output member. In the pedal operation amount detecting device 10 which the sensor member 30 is arranged on the side face of the pedal arm 18 via the pair of support pins 32, 34, and is coupled to the operating rod 22 (output member) via the clevis pin 26, and detects the deformation of the sensor member 30 by the deformation detecting means 52 such as a strain gauge, the operation input portions to which the depression force F is applied and the reaction force applied portion to which the reaction force R is applied are set at the positions that overlap with each other in the direction parallel to the support axis O. Therefore, an offset load due to an offset (deviation in position) between the operation input portions and the reaction force applied portion in the direction parallel to the support axis O is suppressed. Therefore, the posture and deformation manner of the sensor member 30 become stable, and uneven wear of the rotational sliding portions is suppressed. As a result, the detection accuracy and durability improve.
