PROBLEM TO BE SOLVED: To provide manufacture of a device to couple a journal with a serration for transmitting rotation torque having a structure part to support a sleeve with an inside serration. SOLUTION: A minimum inside diameter is provided for a bush 18 and the inside diameter is longer than the maximum outside diameter (d) of a sleeve having a longitudinal slit and after the sleeve 6 is forcibly covered with the bush 18, the diameter of the bush 18 is decreased throughout a part of the length in an axial direction thereof or/and by spreading the region on the end face side of the sleeve 6, the bush 18 is slid to the sleeve 6 and the shape coupling limit thereof. This constitution mounts the bush from the side in spite of a cover surface being formed in a conical shape. |
