Abstract
Disclosed is a shaft inserted member into which a shaft is inserted in a relatively movable manner, and a locking mechanism provided in the shaft inserted member. The tip portion of the shaft includes a locking step portion formed by providing an annular groove or a ring-shaped projection portion. The locking mechanism includes at least two locking pieces arranged around the shaft at an equal interval. The shaft is stopped from slipping off by a tip portion of each of the tip locking portions abutting on the locking step portion. The locking piece can receive the force in a pulling direction in a length direction of the locking piece, whereby a load can be reduced. That is, sufficient strength can be maintained.
