Claims

[Scope of Claim for Utility Model Registration] (1) A caster body, a wheel rotatably attached to the lower end of the caster body via an axle,
A caster with a stopper consisting of a caster pivot shaft rotatably provided at the upper end of the caster body via a bearing, and a stopper means provided in the caster body for simultaneously locking the wheel and the caster pivot shaft by operating a foot lever. A foot lever in which the stopper means is formed in a pedal portion having one end rotatably connected to the caster body via a support shaft and the other end extending outside the caster body, and a pivoting end support shaft of the foot lever. A cross-shaped cam is rotatably supported on the body, one end is pivotally supported on the upper tip of the caster body via a pivot shaft, and the mouth part is openable and closable so that the other end is open and the cam is contained in the mouth. A V-shaped elastic brake piece, a follower rotatably attached to the central part of the pivoting end of the foot lever via a pin and interlocking with the above-mentioned cam, and a follower provided on the lower surface of the foot lever and freely interlocking with the follower. a display means whose end display portion protrudes and retracts from one end on the pedal side of the foot lever; a ratchet means provided at the pivot portion of the foot lever for rotating the cam in only one direction at a predetermined angle by operation of the foot lever; A caster with a stopper comprising a return spring for a foot lever provided between a mounting part and an elastic brake piece. (2) A caster with a stopper according to claim 1, wherein the display means and the ratchet means are each configured to have a dust-proof structure by means of a sealing means.
