Abstract
A brushless motor is provided with a rigid resin member that faces one end of the drive shaft with a predetermined gap therebetween. The rigid member is positioned to be struck by the end of the drive shaft when the drive shaft vibrates. The impact of the collision is absorbed by the elastic deformation of a resilient member that supports the rigid member. This prevents noise from being generated by vibrations of the drive shaft.
