Abstract
A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.
