Abstract
In a brushless motor apparatus, a rotor is rotatbly supported on a stator so that the rotor is rotated by energization of the stator. The stator has a center piece that has a fixing plate at one end. The fixing plate is formed with bosses. Each boss is fixed to a motor holder through a vibration-resistricting cushion. The cushion is shaped cylindrically to be fit tightly on the boss. The cushion is formed with an annular groove on its outer peripheral surface at a position intermediate its axial ends, and is fit tightly in an elliptic fixing hole formed in the motor holder through the annular groove. The cushion has an abutting surface on its inner peripheral wall at the intermediate position so that the cushion abuts the boss at the abutting surface. The abutting surface has an axial length shorter than the entire axial length of the cushion. The cushion is held tightly to the fixing plate by threading a holding plate to the fixing plate in the axial direction.
