In a geared motor, a worm wheel, an O-ring, a transmission plate and an output gear are installed to a support shaft. The O-ring is placed in an inner space of a receiving through hole of the transmission plate, through which the support shaft is received. Grease is applied to an outer peripheral surface of the support shaft. A grease relief passage, which relieves the grease, extends between the output gear and the transmission plate.

A motor apparatus is provided with a yoke housing, a gear housing and a brush holder. A receiving portion of the gear housing receives the worm wheel, etc. therein. The brush holder is interposed between the yoke housing and the gear housing. The worm wheel is provided with a switching plate on one side face thereof, which is in slide contact with contact members. The gear housing is provided with a housing body and a cover. In the housing body is formed a communication hole to communicate an internal spaces of the receiving portion and a yoke housing. The contact members are disposed on the brush holder and on the bottom portion side of the receiving portion with respect to the worm wheel so as to extend through the communication hole into the gear housing.

A core includes a ring body and a plurality of teeth. The teeth extend radially outward form the outer circumference of the ring body. The core is formed by assembling a first core member and a second core member. Each core member has part of the teeth the number of which is half the total number of the teeth. Each tooth includes a tooth body about which the coil is wound, and a magnetism converging portion provided at the distal end of the tooth body. The tooth height of each tooth body gradually increases from a distal section to a proximal section of the tooth body. The tooth width gradually decreases from the distal section to the proximal section. The wire is wound about each of the teeth of the first and second core members. Then, the first and second core members are assembled to form the core. Accordingly, a rotor core having a high coil accommodation efficiency and a high coil space factor is obtained.

A heat sink member divides a circuit board into a first circuit part and a second circuit part. The first circuit part includes circuit elements, such as a transistor, an electric current sensing resistor and a choke coil, which generate heat upon operation thereof. The second circuit part includes a control circuit, which controls operation of the motor.

Teeth of a first core sub-part and teeth of a second core sub-part are alternately arranged in a circumferential direction. Each tooth has a tooth main body, which may include two tilted portions at two opposed circumferential ends, respectively, of the tooth main body. Each tilted portion is angled relative to a corresponding direction parallel to the axial direction of the core. Each one of the first and second core sub-parts may have fitting recesses and fitting projections, which are engaged with the fitting projections and the fitting recesses of the other one of the first and second core sub-parts. Each tapered wall surface of each fitting recess is angled relative to a corresponding direction parallel to the axial direction. Similarly, each tapered wall surface of each fitting projection is angled relative to a corresponding direction parallel to the axial direction.

Assume that the position of a sun visor main body is adjusted by an occupant when incident light having the incident angle θ1 has entered a vehicle passenger compartment. Then, a straight line L1 is obtained that passes through the distal end position S1 of the moved sun visor main body and is inclined by the same angle as the incident angle θ1. At this time, the intersection between a straight line Y1, which passes through an eye position P0 of a average sized person and extends along the vertical direction of a vehicle, and the straight line L1 is estimated as an eye position P1 of the occupant. Thereafter, a light blocking control is performed in accordance with the estimated eye position P1.

A yoke is substantially cylindrical and has an opening portion. A brush holder member is secured to the opening portion of the yoke. The brush holder member retains a pair of supply brushes. A housing member is secured to the opening portion of the yoke on the outside of the brush holder member and covers the opening portion. A pair of securing pieces is formed integrally with the yoke. The securing pieces secure the brush holder member and the housing member to the yoke.

A driving-side rotator of a clutch has a connecting hole, within which a connecting portion of a rotatable shaft is loosely fitted while providing a space between the connecting hole and the connection portion. The connecting hole of the driving-side rotator is engageable with the connecting portion of the rotatable shaft in a rotational direction to integrally rotate with connecting portion of the rotatable shaft. Two positioning holes are provided in a brush holder, and two positioning projections are provided in a gear housing to allow direct positioning of the brush holder and the gear housing relative to each other.
