装着した部材の軸方向への移動を規制するストツ
パリングを、使用温度よりも十分に低い第１の温
度において形状を回復し、当該第１の温度よりも
低い第２の温度において変形可能な一方向形状記
憶合金部材により環状に形成し、且つ前記嵌合溝
に嵌合する孔を前記第１の温度において前記軸の
軸径よりも小径且つ環状溝に嵌合可能とし、前記
第２の温度において当該孔を拡径させて前記環状
溝に嵌合させ、前記使用温度において逸脱不能に
嵌合させることを特徴とするストツパリング。 A stopper ring that fits into an annular groove formed on the circumferential surface of the shaft to restrict the movement of a member attached to the shaft in the axial direction is restored to its shape at a first temperature sufficiently lower than the operating temperature. The hole is formed into an annular shape by a one-way shape memory alloy member that is deformable at a second temperature lower than the first temperature, and the hole that fits into the fitting groove is smaller than the shaft diameter of the shaft at the first temperature. The stopper ring has a small diameter and can be fitted into the annular groove, the diameter of the hole is expanded at the second temperature to fit into the annular groove, and the stopper ring is fitted into the annular groove in a manner that cannot be removed at the operating temperature.
