Abstract
An object of the present invention is to improve the easiness of steadily maintaining the magnitude of treading on a foot-operated operating element while mitigating a feeling of treading on a wall at the time of start of treading on the operating element. A pedal-operated operation device includes a pedal arm, a support housing, a spring for urging the pedal arm in a direction of return, a first shim and a second shim. A frictional engagement portion of the second shim is higher in maximum static friction force than a frictional engagement portion of the first shim. The second shim has a region in which the elastic modulus of the second elastic deformation portion is lower than that of the first shim, in terms of elastic deformation at the time when the pedal arm moves relative to the support housing.
