Claims

[Scope of utility model registration request]

A caster frame 4 is rotatably attached to a fixed shaft 2 protruding below the base plate 1 via a bearing member 3, and a guide plate 6 having an engaging portion 5 is attached to the lower end of the fixed shaft 2. The operating member 9, which includes a protrusion 8 that slides on the guide plate 6 and is biased by a spring 7 so as to engage with the engagement portion 5, is attached to the caster frame so as to be swingable between the engagement position and the disengagement position. A caster having a structure in which a locking means 10 is provided on a base plate 1 and an operating member 9, the locking means 10 being pivotally supported to a caster frame 4 and brought into contact with the caster frame 4 to shift the protrusion 8 to the engagement position when the caster frame 4 rotates.
