Claims

[Scope of Claim for Utility Model Registration] A partition wall is provided in a semi-cylindrical wheel cover, a wheel is rotatably attached to the partition wall via an axle, a through hole for sliding the lock slider is provided in the partition wall, and a wheel cover is provided. A push button insertion hole is formed in each of the holes, and when the push button inserted retractably into the hole is pressed, a cam having a heart-shaped cam groove and a lock slider attached to the lower end of the push button are loosely fitted into the push button. The caster is configured to separate the stopper piece of the lock slider from the inner gear of the wheel through the holder, and the holder is provided with a pin hole communicating with the heart-shaped cam groove at one end of the holder forming the hole, and the other. In addition to forming a pin locking portion at each end, a linear guide portion to be inserted into the pin hole and an engaging portion for preventing slipping out that engages with the pin locking portion are connected to each other along the outer shape of the holder. A caster is provided with a pin integrally formed with the pin holder, and is mounted and supported on a holder through a mounting hole bored in a partition wall at the outer edge of the pin holder.
