Abstract
An impact-absorbable power transmission device is constituted by establishing a frictional spline connection between a shaft and a pipe to allow an axial slide therebetween and to forbid a relative rotation therebetween. An inner race of a universal joint is fixed to another end portion of the shaft by press-fitting. A flange for receiving a press-fitting force of the inner race is formed at an intermediate portion of the shaft. Therefore, the power transmission device ensures an impact absorbing performance while avoiding a lowering of a mechanical strength caused by the inner race installing operation.
