項に記載のプロペラシヤフト。[Claims for Utility Model Registration] (1) Comprising an inner cylinder and an outer cylinder arranged concentrically, and an annular elastic body inserted in a space between the inner cylinder and the outer cylinder. In a propeller shaft of a type that transmits rotational torque by On the other hand, a propeller shaft characterized in that a gap is formed to increase the contact area of the elastic body used for torque transmission as the elastic body is elastically deformed when the rotational torque is transmitted. (2) The gap is such that the inner peripheral surface of the outer cylinder has an elliptical cross-sectional shape, and the outer peripheral surface of the elastic body has a cross-sectional shape that is smaller than the major axis of the ellipse of the inner peripheral surface of the outer cylinder and is elliptical. The propeller shaft according to claim 1, which is formed between the inner circumferential surface of the outer cylinder and the outer circumferential surface of the elastic body by forming an elliptical shape with a longer axis larger than a shorter axis. . (3) The gap is formed by providing a first unevenness on the outer circumferential surface of the inner cylinder and providing a second unevenness substantially corresponding to the first unevenness on the inner circumferential surface of the elastic body. and the second unevenness, the utility model registration claim 1 or 2 being formed between opposing surfaces at least in the circumferential direction.
Propeller shaft as described in Section.
