A caster, for example for mounting the wheels of a baby carriage has a fixed bracket (14), a rotary yoke (15) rotatably supported by the fixed bracket (14), and a wheel (17) rotatably supported by the rotary yoke (15) with the aid of an axle (16). The rotary yoke (15) is formed an elongated opening (29) which extends horizontally at right angles to the axle (16). The axle (16) is held in the elongated opening (29) and is horizontally movable in the elongaged opening (29) under the influence of a guide opening or slot in an axle guide which intersects with the elongated opening. |
