发明名称 Motor
摘要 A motor in an example of the invention forms a stator core stack by laminating a plurality of straight cores having a core back, a tooth, and a linking part for linking the core backs. In the stator core stack, the linking portion is folded and deformed the linking portion so as to join an end surfaces of the straight core, and a core back outer peripheral portion is formed at the back side of the core back, and the diameter of the core back outer peripheral portion is formed same as or shorter than the diameter of the inner peripheral surface of the housing, and is disposed in the housing. A bar-like member is press-fitted in the axial direction between both the end surfaces of the straight core. In other example of motor, an engaging portion extending in the axial direction and projecting in the radial inward direction is formed in the inner peripheral surface of the housing, and the end surfaces of the straight core are engaged or fitted with the engaging portion.
