PROBLEM TO BE SOLVED: To provide a caster which is locked in movement by a load to be applied when the canister is loaded with cargo or a person is seated.SOLUTION: A caster to be locked in movement by a load includes an attachment part for attaching a wheel support body for supporting a wheel and a caster body to an object. The attachment body is connected so as to be slidably expanded/contracted. When no load is applied to the caster, it is expanded, while when a load is applied, it is contracted. A stop member in the attachment part drives a second stop member directly or arranged in the wheel support body to collide with a wheel or a floor, thereby preventing the caster from moving. |
