Abstract
A return mechanism is achieved which requires only a small force for operation. In one aspect of the present invention, a return mechanism () includes: a first spring () that acts between an operating section () and a working section (); and a second spring () that acts between the operating section () and a base (). A direction in which the second spring acts when the operating section () is in a first position is not parallel to a direction in which the second spring () acts when the operating section () is in a second position. A component which, of a force of the second spring, acts in a direction of motion of the operating section () is smaller when the operating section () is in the second position than in the first position.
