摘要： A brushless motor comprises a parts protecting case; a drive shaft rotatable about its axis relative to the parts protecting case; a fixed housing for rotatably holding therein the drive shaft; a stator tightly held by the fixed housing; a shock absorbing unit interposed between the fixed housing and the parts protecting case to suppress transmission of vibration of the fixed housing to the parts protecting case; a yoke connected to the drive shaft to rotate therewith; and a plurality of magnets held by the yoke. The yoke has a vibration damping structure to suppress or at least minimize transmission of vibration of the yoke to the drive shaft.
