Alternatively, by interposing the pin 12 and pairing each pin with each arm or intermediate body in a cylindrical pair, torque can be transmitted even under conditions where the joint center and the intersection of the extension lines of the input/output shafts A and B do not coincide. In the universal joint, an intermediate body is positioned on the inner peripheral side of the arms 21 and 31, and the cylindrical pin 11 or pin 12 is passed through each of the arms in a pair of cylindrical pairs, and the cylindrical pin is inserted into the intermediate body. A universal shaft joint that is screwed to the outer periphery of an intermediate body 1 by a penetrating mounting screw N, and a tool engagement hole such as a hexagonal hole D is formed in the end surface of the head H of the mounting screw N. Consisting of a first connecting body 2 connected to the input shaft A, a second connecting body 3 connected to the output shaft B, and an intermediate body 1 connecting these, a pair of connecting bodies 2 are arranged at symmetrical positions on the outer circumference of the first connecting body 2. The arms 21, 21 of the intermediate body 1 are made to protrude inward in the axial direction, and a pair of arms 31, 31 are similarly made to protrude inward in the axial direction at symmetrical positions on the outer periphery of the second connecting body 3.
