ABSTRACT:
A caster has a fixed bracket (15), a rotary yoke (16) rotatably supported on the fixed bracket (15), and a wheel (2) rotatably supported on the rotary yoke (16) by a horizontal axle (16). The axle (16) is mounted for movement in a predetermined range in a horizontal plane in a direction which is at right angles to the axle. The rotary yoke (16) includes an automatic locking member (17) capable of moving between first and second positions in response to the movement of the horizontal axle. The fixed bracket (15) is provided with an engaging recess (36) for engaging the automatic locking member (17) to inhibit the rotation of the rotary yoke (16) when the fixed bracket (15) and the rotary yoke (16) are in a predetermined positional relationship and when the automatic locking member (17) is in the first position.
