Abstract: The swing member (63) to be subjected to swinging drive is integrally provided to the output shaft (56) outside the speed reducer case (52), the speed reducer case (52) is provided with a pair of swing regulating portions (61, 62) which prevents the swing member (63) from being moved beyond the wiping-allowable limit angle (b°) by contacting the swing member (63). As a result, the swing member (63) and the swing regulating portions (61, 62) can collectively form the regulating member (60). As a result, essential components (such as fixing plate) can be omitted from the conventional wiper apparatus. Therefore, the wiper apparatus can be improved in assembly workability, size and weight by reducing the number of components thereof, and provided with a regulating member (60) which prevents the wiper member being moved beyond the wiping-allowable limit angle (b°).

Abstract: A rotor is provided with: a rotor core (32); a plurality of permanent magnets (33); a substantially tubular magnet cover (71); and a load reception block (70). The rotor core (32) rotates integrally with a rotary shaft of a motor. The permanent magnets (33) are arranged on the outer peripheral part of the rotor core (32). The magnet cover (71) covers the exterior of the plurality of permanent magnets (33) and the rotor core (32), and has a flange part which is bent radially inward at the end along a rotation axis. The load reception block (70) is disposed between the flange part and the end surface of the rotor core (32) in a direction along the rotation axis, and abuts against the flange part and the rotor core (32).

Abstract: A motor case (31) in which a stationary portion (35) is fixed, and a gear case (41) in which a gear mechanism (SD) is accommodated are made of aluminium, most heat generated from the stationary portion (35) at the time of actuation of a brushless wiper motor (20) can be directly dissipated outside from the motor case (31). That is, compared with conventional technique, heat transmitted to the motor case (31) can be efficiently dissipated outside, and the motor case (31) does not reach high temperature. Therefore, as a matter of course, reduction in size and weight can be achieved, suppression of electromagnetic noise can be achieved, and heat-resistance strength can be enhanced. Expensive components capable of resisting high temperatures are not required, and reduction in manufacturing cost can be achieved.
