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：导热构件（60）设置在构成控制器（54b）的外壳（53）和FET模块（54f）之间，用于将FET模块（54f）的热量释放到壳体（53）。因此，FET模块（54f）的热量可以经由导热构件（60）和壳体（53）散发到外部。由于壳体（53）由铝构成，壳体（53）的表面积可以增加到比现有的冷却翅片构件大，并且FET模块（54f）的热量可以散发到外部，DR 侧刮水器马达（21）的尺寸可以减小并且提高冷却效率。此外，由于冷却翅片构件没有以常规方式插入到壳体盖54中。因此，可以容易地模制壳体盖（54），并且可以提高刮水器马达的组装操作性。

摘要： A motor case part (30) having a stator (36) and a gear case part (50) having a reduction mechanism (SD) are integrally formed of the same material. In this manner, heat is directly dissipated from the motor case part (30) to the outside without the gear case part (30). Therefore, a brushless wiper motor (20) can be improved in heat radiation performance so as to enhance strength in high temperature can be realized. By manufacturing the motor case part (30) and the gear case part (50) from aluminum, while sufficient radiation performance is secured, a thickness thereof is made thin and lack in rigidity can be overcome. Furthermore, It is unnecessary to manufacture the motor case part (30) and the gear case part (50) individually and it is also unnecessary to perform pressing to a steel plate like the conventional art. Therefore, workability of the motor case part (30) and the gear case part (50) can be improved.
