PURPOSE:To readily assemble a motor by forming a peripheral groove on a rotor shaft disposed at the outer end face of a bearing having a bracket, engaging a resin ring with the groove, and forming a cushion at the ring as a stopper. CONSTITUTION:A stator core 1 is molded with resin 2 to form a stator 3. The stator 3 is formed at both sides with engaging portions 6, 7 of brackets 4, 5, and the brackets 4, 5 are engaged from outside with the engaging portions 6, 7, respectively. Bearings 8, 9 are engaged from outside with the brackets 4, 5 to support a rotor shaft 10. The shaft 10 is formed with peripheral grooves 11, 12 at the outer positions of the bearings 8, 9, and stoppers 13, 14 are engaged with the grooves 11, 12. The stopper 14 is formed of resin, and formed with a plurality of cushions 16 formed by bending it toward outer peripheral side.
