Abstract
A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.
