Claims

[Scope of utility model registration request]

An input/output shaft yoke, one end of which is connected to the input/output shaft and the other end of which is formed into a U-shape, and two that intersect at right angles at two points on the outer periphery, and the input shaft yoke and the output shaft yoke can be fitted facing each other. A book groove is fitted to a sphere formed around the outer periphery,
In a universal joint that transmits rotational torque from an input shaft to an output shaft via a sphere, the fitting portion of the input/output shaft yoke with the sphere and the groove of the sphere are each shaped into an arc shape to form the input/output shaft yoke. A universal joint characterized by being fitted with a sphere.
