Abstract
A starting device includes a fluid coupling, an electric motor, and a restriction mechanism. The electric motor includes a rotor and a stator. The rotor is disposed radially outside the fluid coupling. The restriction mechanism restricts relative rotation between the fluid coupling and the rotor. The restriction mechanism includes a first key groove, a second key groove, and a key body. The first key groove is provided on an inner peripheral surface of the rotor to extend in an axial direction. The second key groove is provided on an outer peripheral surface of the fluid coupling to extend in the axial direction. The second key groove is lesser in length than the first key groove. The key body includes a first key portion and a second key portion. The first key portion is fitted to the first key groove. The second key portion is fitted to the second key groove.
