Abstract: An electromagnetic clutch has an inner ring portion which is formed in a cylindrical shape and holds a bearing on an inner surface thereof, and a friction portion which has a friction surface extending in the radial direction from the inner ring portion. The electromagnetic clutch has an outer ring portion which is arranged around the inner ring portion, and is formed in a cylindrical shape, and is joined to the friction portion. A joined portion which joins the outer ring portion and the friction portion is disposed between the outer ring portion and the friction portion. The joined portion is formed by the friction welding process.
