PROBLEM TO BE SOLVED: To provide a practical and simple locking member which can solve the conventional faults that assembly and disassembly are complicated and leakage oil can not be avoided. SOLUTION: This locking member for a restricted body 20, in which a cavity part 202 for restricting movement in a certain direction is formed in one end part, is formed into a ring shape having a closed hollow part 201, and has elasticity that when the restricted body 20 receives external force, one end thereof is penetrated through the hollow part 201, and after external force is eliminated, the one end is restricted its movement by the locking member.
