ント自体の振動については特に考慮されていない。[Prior Art] A constant velocity joint connects two rotating bodies and transmits rotational torque from one rotating body to the other rotating body at the same angular rotational speed even when the coupling angle changes. Such a constant velocity joint has an outer having four cup-shaped parts at one end connected to one rotating body and the other end having four cup-shaped parts, and one end held in a recess in the outer and connected to the other end or the other rotating body. It consists of an inner body, and an intermediate body such as a pole that is interposed between the outer and the inner body and transmits torque. Conventional constant velocity joints do not particularly consider vibrations of the constant velocity joint itself.

However, when torsional vibration occurs on the drive shaft, the damper provided at the center of the drive shaft cannot effectively absorb the torsional vibration. In order to effectively absorb this torsional vibration, it is necessary to provide a damper in the constant velocity joint itself.
