ABSTRACT:
The operation torque during disengaging of clutch projections out of clutch grooves, is effectively suppressed from excessively increasing immediately after start of device assembling. In a door mirror device, a gear plate has clutch grooves made substantially in trapezoidal form, in circumferential cross-section, increasing in width from a groove bottom to an opening end. A clutch disk has clutch projections made substantially in trapezoidal form, in circumferential cross-section, decreasing in width in taper form from a base toward a tip wherein the top surfaces are made in an inverted radial form decreasing in width from inner periphery to outer periphery. Due to this, when a torque exceeding a set value is transmitted to the gear plate, the pressure-contact area of the clutch projection with the clutch groove gradually moves from inner periphery to outer periphery while moving the clutch disk upward against a bias force of a clutch spring.
