To enable an input torque to be accurately detected even when a misalignment of the axes of both rotators occurs in an input torque detecting device of power-assisted vehicle to detect an input torque to an input operating member on the basis of a rotational phase difference which occurs between a first rotator rotating in synchronization with the rotation of the input operating member and a second rotator rotating in synchronization with the rotation of a driving wheels.
A first magnetic ring 131 is formed by providing north poles 131N and south poles 131S in a ring shape for the first supporting member 133 formed of synthetic resin to rotate together with the first rotator. A second magnetic ring is formed by providing north poles and south poles in a ring shape for the second supporting member 140 formed of synthetic resin to rotate together with the second rotator. One of the inner circumference and outer circumference of the first supporting member 133 and the other of the inner circumference and outer circumference of the second supporting member 140 come into contact with each other at a plurality of locations at intervals in the circumferential direction.
