摘要:
The outer rotor-type blushless motor comprises: a stator including a cylindrical housing, a stator core having stator pole teeth and a bearing coaxially incorporated in a cylindrical hole of the hosing; and a rotor including a rotor yoke, a rotor hub provided to the rotor yoke and a rotor shaft rotatably supported by the bearing. A first resin washer, through which the rotor shaft is pierced and which contacts an end face of the rotor hub, and a second resin washer, which contacts an end face of the bearing incorporated in a center hole of the stator core, contact each other. The second resin washer has an elastic projected section fitted in a concave section formed in the center hole of the stator core.
