1. A pedal device comprising:
a shaft;
a pedal configured to rotate together with the shaft about an axis of the shaft when being stepped on by an operator;
a support configured to rotatably support the shaft;
a reaction force generating mechanism configured to generate a reaction force with respect to a stepping force of the operator, by an elastic deformation against to the stepping force of the operator applied to the pedal when the pedal receives force from the operator; and
a connecting rod including: an arm portion connected to a back surface of the pedal, which is a surface of the pedal opposite to a stepping surface stepped on by the operator; and a push portion connected to the arm portion, wherein
the push portion is configured to transmit force from the pedal to the reaction force generating mechanism by contacting the reaction force generating mechanism when the pedal is stepped on by the operator,
the connecting rod is connected to the back surface of the pedal, to rotate with the pedal about the axis of the shaft when the operator steps on the pedal, while an angle defined between the back surface of the pedal and an axis of the connecting rod is maintained,
the push portion has a push-side contact surface that contacts the reaction force generating mechanism when the pedal is stepped on by the operator,
the push-side contact surface is convex toward the reaction force generating mechanism,
the reaction force generating mechanism has a mechanism-side contact surface that contacts the push portion when the operator steps on the pedal, and
the mechanism-side contact surface is recessed toward an inside of the reaction force generating mechanism.
