入力部材に固定する。First, when the set screw screwed into the threaded hole of the cylindrical body is loosened, the tightening of the output member by the cylindrical body and the collar loosens.
The output member is now free to rotate relative to the input member. In this state, after adjusting the output member to the desired angle with respect to the input member, the cylindrical body is pressed against the output member by tightening the set screw again and crimping its conical end into the conical hole of the input member. It is fixed to the output member and the input member using the collar and the cylindrical body.

数の円錐孔９を形成する。In the embodiment shown in the drawings, 1 is an input shaft, and 2 is a cylindrical input member that is integrally fixed to the input shaft 1 with a key 3, a set screw 4, or the like. Reference numeral 5 denotes a collar integrally formed at the front end of the input member 2. Reference numeral 6 denotes an output member, which is loosely fitted around the outer periphery of the input member 1 so as to be freely rotatable and movable in the axial direction. In the figure, a sprocket is shown as the output member, but a timing belt pulley or gear may also be used. Reference numeral 7 denotes a cylindrical body, which is fitted onto the outside of the input member 2 so as to be movable in the axial direction. A plurality of radial screw holes 8 are formed in this cylindrical body 7, and a plurality of conical holes 9 are formed in the input member 2 facing each of the screw holes 8.
１０は各ネジ孔８に螺合せしめるセットネジで、その内
