Abstract: A thermally-conductive member (60) is provided between a housing (53) and a FET module (54f) constituting a controller (54b), and used to release heat of the FET module (54f) to the housing (53). Therefore, heat of the FET module (54f) can be dissipated to outside via the thermally-conductive member (60) and the housing (53). Since the housing (53) is made of aluminum, a surface area of the housing (53) can be increased to become larger than the conventional cooling fin member, and heat of the FET module (54f) can be dissipated to outside, the DR-side wiper motor (21) can be reduced in size and improved in cooling efficiency. Furthermore, since a cooling fin member is not inserted in the case cover (54) in a conventional manner. Therefore, the case cover (54) can be molded with ease, and the wiper motor can be improved in assembly workability.

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°).
