Summary:To provide a geared motor that can suppress generation of an abnormal sound and has a simple structure with a smaller number of components.SOLUTION: A geared motor 2 has an electric motor 20, a speed reduction gear 30, a case 10, and a housing 40 covering the electric motor 20 and the speed reduction gear 30 together with the case 10. Rotational power of the electric motor 20 is transmitted to the speed reduction gear 30 via a motor gear 21. The speed reduction gear 30 is supported rotatably around a speed reduction gear rotation axis 30Z by the case 10 and the housing 40. The speed reduction gear 30 is provided with one of a guide groove AM1, which is provided to be continuing in a circumferential direction about the speed reduction gear rotation axis 30Z, and a guide projection part AT1 inserted in the guide groove AM1, and the other of them is provided on at least one of the housing 40 and the case 10. The guide projection part AT1 is provided on at least a part of the circumferential direction about the speed reduction gear rotation axis 30Z.SELECTED DRAWING: Figure 3 【課題】異音の発生をより抑制できるとともに、より少ない部品点数でシンプルな構造を有するギヤードモータを提供する。【解決手段】ギヤードモータ2は、電動モータ20と、減速ギヤ30と、ケース10と、ケース10とともに電動モータ20と減速ギヤ30を覆うハウジング40とを有する。電動モータ20の回転動力はモータギヤ21を介して減速ギヤ30に伝達される。減速ギヤ30は、ケース10とハウジング40にて、減速ギヤ回転軸線30Zまわりに回転自在に支持されている。そして、減速ギヤ回転軸線30Zを中心として周方向に連続するように設けられた案内溝AM1と、案内溝AM1に差し込まれた案内凸状部AT1と、の一方が減速ギヤ30に設けられ、他方がハウジング40とケース10との少なくとも一方に設けられている。また、案内凸状部AT1は、減速ギヤ回転軸線30Zを中心として周方向の少なくとも一部に設けられている。【選択図】図3
