Claims

[Scope of utility model registration request]

A drive part connected to the drive side of a power transmission shaft with a split middle and formed with either an engagement protrusion or a cam surface that can engage with each other and can rotate relative to each other, and a driven part of the power transmission shaft. a driven part connected to the side and formed with the other of the engagement protrusion and the cam surface, and supports either the driving part or the driven part so as to be movable in the axial direction on the power transmission shaft. In addition, in the damper clutch which is provided with a set spring biased toward the other side, when the damper clutch is under no load, the engaging protrusion is predetermined on the slope of either the deceleration or acceleration side of the cam surface. 1. A power transmission device for a vehicle, comprising: an elastic return member that maintains a constant relative rotational position between the driving portion and the driven portion so as to return to an initial set position.
