部を形成した キヤスタ。[Claims for Utility Model Registration] A shaft hole is formed in one side of the caster body that passes through it in the vertical direction, and a mounting shaft for rotatably holding the caster body is inserted into the shaft hole, and the lower end of the mounting shaft is inserted into the shaft hole. A caster for screwing a mounting screw part at the upper end of the mounting shaft onto a fixed part by rotation of a rotational force input part formed in the shaft hole, the caster having an inner surface inclined in the inner diameter direction of the shaft hole at the lower end of the shaft hole. A slip-off preventing portion is integrally formed, a groove is carved at the rear side of the slip-off preventing portion to allow tilting of the fall-off preventing portion in an outer radial direction, and a shaft hole is formed on the lower end side of the mounting shaft. At the time of insertion, a spreading part is formed at a position corresponding to the lower part of the stopper part at the lower end of the shaft hole to spread out the stopper part in the outer radial direction, and a part of the stopper part is formed on the upper part of the spread part. A caster with a recess that is smaller in diameter than the inner diameter of the caster and allows the retaining part to return elastically.
