大なるものとする。[Claims for Utility Model Registration] A stepped shaft having a large diameter portion and a small diameter portion, and a cylindrical body that is inserted into the stepped region of the shaft and fixes a component at a predetermined position in the axial direction to the large diameter portion of the shaft. , wherein the inner diameter of the cylindrical body has a large inner diameter portion and a small inner diameter portion to fit the shaft, and the inner diameter of the cylindrical body has a large inner diameter portion and a small inner diameter portion that fit the corresponding shaft. The cylindrical body has a hydraulic chamber in a stepped part of the inner diameter, and the hydraulic chamber has a hole communicating with the outside of the cylindrical body. and an assembly of a shaft for fixing a shaft part and a cylindrical body, characterized in that the assembly of the cylindrical body satisfies the following conditions A to C. A plurality of circumferential grooves 45 and 15 are provided on the inner surface of the large inner diameter portion 44 of the cylindrical body 40 and on the surface of the small diameter portion 13 of the shaft 10, each having a constant pitch p and communicating with each other. (B) When the cylindrical body 40 is assembled on the shaft 10, the circumferential grooves 45 and 15 have one end 4 located on the stepped portion 11 side.
5a and 15a communicate with the hydraulic chamber, and the other ends 45b and 15b are connected to annular grooves 47 and 17 without reaching the side ends of the cylindrical body 40. (C) The distance 1 between the annular grooves 47 and 17 and the cylindrical body side end is larger than the pitch p of the plurality of circumferential grooves 45 and 15.
