Claims

[Claim for Utility Model Registration] In a shaft joint that transmits torque by charging hydraulic oil between an inner cylinder built into the input shaft for torque transmission and an outer cylinder built into the output shaft, this hydraulic oil is used. A circulation path through which hydraulic oil is taken out from one end and then charged again; An inclined surface a on the inner peripheral surface of the outer cylinder into which hydraulic oil enters from the circulation path, increasing the distance from the inner cylinder in accordance with the traveling direction of the inner cylinder; On the inner peripheral surface of the outer cylinder on the outlet side of the hydraulic oil, there is a slope b that narrows the distance between the inner cylinder and the inner cylinder according to the direction of movement of the inner cylinder, and the inner cylinder expands and contracts to follow the distance between the slopes and the inner cylinder. A shaft joint having a torque control function, characterized by being provided with a blade that rotates together with the shaft joint.
