Claims

[Claims for Utility Model Registration] The first connecting body 2 connected to the input shaft A and the second connecting body 3 connected to the output shaft B are connected via the intermediate body 1, and the first connecting body 2 A pair of arms 21, 21 protruding from the outer periphery in the axial direction and the intermediate body 1 are cylindrically coupled at their diametrical fitting portions, and a pair of arms 31 protruding from the outer periphery of the second connection main body 3. , 31 and the intermediate body 1 in a cylindrical pair at their diametrical fitting portions, torque can be transmitted even under conditions where the center of the joint and the intersection of the extended line of the input shaft A and the output shaft B do not coincide. In this universal joint, arms 21, 21 are integrally formed on the flange 20 of the first connecting body 2, a radial through hole 22 is formed in the arm 21, and a flange 30 of the other second connecting body 3 is formed integrally with the arms 21, 21. Arms 31, 31 are integrally formed in the arm 31, and a radial through hole 3 is formed in the arm 31.
2, and pins protrude in the radial direction at positions where the outer periphery of the main body part 10 of the intermediate body 1 is divided into four, and a pair of pins 11, 1 located on opposite sides of the intermediate body 1 are formed.
1 into the through holes 22, 22, and the other pair of pins 12, 12 are inserted into the through holes 32, 32. A universal joint having a screw body screwed into the outer peripheral surface of the screw body, and a tool engagement hole such as a hexagonal hole D formed in the end face of the head H of the screw body. A first connection body 2 connected to the input shaft A and a second connection body 3 connected to the output shaft B are connected via the intermediate body 1, and the first connection body 2 is made to protrude in the axial direction from the outer peripheral part thereof. The pair of arms 21, 21 and the intermediate body 1 are coupled in a cylindrical pair at the fitting portion in the diametrical direction, and the pair of arms 31, 31 protruding from the outer periphery of the second connecting body 3 and the intermediate body 1 are connected to each other. The first universal joint is capable of transmitting torque even under conditions where the center of the joint and the intersection of the extended line of the input shaft A and the output shaft B do not coincide by pairing the shafts in a cylindrical manner at their diametrical fitting portions. Arms 21, 21 are integrally formed on the flange 20 of the connecting body 2, and the pins 11 are made to protrude in the radial direction from the arms 21, and arms 31, 31 are integrally formed on the flange 30 of the other second connecting body 3. The arm 31 is formed with a pin 12 protruding in the radial direction, and the main body 10 of the intermediate body 1 is an annular body located on the outer periphery of the first connecting body 2 and the second connecting body 3. 10 is divided into four equal parts, and the pin 11 is inserted into one of the pair of through holes located on opposite sides.
, 11, and the pins 12, 12 are inserted into the other pair of through holes. A universal joint with a threaded body that is screwed into the outer circumferential surface, and a tool-accommodating hole such as a hexagonal hole D formed in the end face of the head H of this threaded body.
