摘要： 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°).

摘要： 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.
摘要翻译：在构成控制器（54b）的壳体（53）和FET模块（54f）之间设置有用于将FET模块（54f）的热释放到壳体（53）的热传导构件（60）。因此，FET模块54f的热量能够经由热传导构件60和壳体53散发到外部。由于壳体53由铝制成，所以壳体53的表面积可以比现有的冷却翅片部件大，并且能够将FET模块54f的热散发到外部，因此DR 侧刮水器马达（21）可以减小尺寸并提高冷却效率。此外，由于冷却翅片部件不以常规方式插入壳体盖（54）中。因此，能够容易地成型壳体罩（54），能够提高组装作业性。
