To provide a motor having a bearing holder capable of miniaturizing the motor in the axial direction.SOLUTION: A motor has a motor part having a shaft rotating around a center axis, a cylindrical housing body provided with a motor part storing space storing the motor part, a bearing supporting an end of one side in the axial direction of the shaft, and a bearing holder 85. The bearing holder 85 has a cylindrical part holding the bearing and multiple leg parts 88 extended radially outward from the cylindrical part. A space S provided between the leg parts 88 overlaps the motor storing space when viewed from the axial direction.SELECTED DRAWING: Figure 4 【課題】モータを軸方向に小型化することが可能なベアリングホルダを備えるモータを提供する。【解決手段】中心軸線を中心として回転するシャフトを有するモータ部と、前記モータ部を収容するモータ部収容空間が設けられる筒状のハウジング本体と、前記シャフトの軸方向一方側の端部を支持するベアリングと、ベアリングホルダ８５と、を備える。ベアリングホルダ８５は、前記ベアリングを保持する筒状部と、前記筒状部から径方向外側に延びる複数の脚部８８と、を有する。脚部８８同士の間に設けられる隙間Ｓは、軸方向から見て、前記モータ部収容空間に重なる。【選択図】図４
