Abstract

See full text

A caster wherein a rotary yoke (4) rotatably supporting a wheel (8) is supported by a vertically extending shaft (5) so that it is rotatable relative to a fixed bracket (3). The rotary yoke (4) is supported so that it is vertically movable relative to the fixed bracket (3) while overlapping the lower end of the latter. A cushion spring (6) downwardly urging the rotary yoke (4) is interposed between the fixed bracket (3) and the rotary yoke (4). Further, the caster is provided with a locking mechanism (10) for selectively stopping the inherent function of the caster of changing the direction of travel of the wheel.
