发明名称 Motor
摘要 A motor comprises a stator, a rotor being arranged in and facing said stator, an urging member which urges a center rotation shaft of the rotor in an axial direction, and a bearing which rotatably holds the rotor at a predetermined position while receiving an urging force by the urging member. The stator is provided with a resin coil bobbin made by insert molding and integratedly assembled with a metal stator core. The stator core is arranged in and faces the rotor and forms a magnetic circuit therewith. The coil bobbin is arranged at the end side of the rotor. A holding portion is integratedly formed, the holding portion holds the urging member so as to urge the rotor to the bearing side. A curling base is fitted in. The curling base is formed such that a flat plate-shaped metal plate is rounded from outside of a winding wound by the electric coil bobbin in the circumference direction of the stator.
