Abstract
A variation reduction mechanism of a stop position of a pointer includes a return gear that is driven in conjunction with a time display mechanism, a slip torque spring (friction member) that contacts the return gear to apply a friction force to the return gear to be driven, and a return spring (return spring member) that applies, to the slip torque spring, a torque of the return gear in a direction (dashed line arrow—R direction) opposite to a normal hand movement direction (arrow R direction).
