Abstract
A first stopper device is arranged between an output element of a planetary gear unit and a drive rotation member driven by an output shaft of an engine. The first stopper device stops a relative rotation therebetween when a relative rotation angle therebetween comes to a first predetermined degree. A second stopper device may be arranged between a free element of the planetary gear unit and an input element of the planetary gear unit. The second stopper device stops a relative rotation therebetween when a relative rotation angle therebetween comes to a second predetermined degree.
