摘要： Disclosed is a motor unit that includes: a rotary electrical machine that has a cylindrical stator, a rotor disposed coaxially with the stator, a shaft disposed coaxially with the rotor, and a cylindrical case that houses the stator and the rotor; and a drive unit that has a swell swelling toward the case and is fixed to a circumferential surface that is located in a radial direction of the rotor and is the case. The case has a recess that corresponds to the swell.

摘要： A silent chain includes a first link, a second link, and coupling pins. The first link is configured from one or more first link plates that include a pair of first pin holes. The second link is configured from one or more second link plates that include a pair of second pin holes. The coupling pins are inserted through the respective first pin holes of the first link plate and the respective second pin holes of the second link plate. The coupling pins alternately couple the first link and the second link together along a chain drive direction so as to enable the first link and the second link to flex. Abrasive particles are embedded in inner peripheral faces at the pin holes of the first link plate and the second link plate.
