キャスタ。A ball rolling element and a receiver with closed curved grooves arranged on both sides of the ball rolling element and small balls that roll on the outer periphery of the ball rolling element are installed on the inner surface, and a steering shaft is erected at the upper end. The vertical plane containing the center of the ball rolling element is inclined to the plane containing the center of the group of small balls that receive the load, so that the ball rolling element rolls in the direction of the pushing force acting laterally. A pole caster, characterized in that the cylindrical body is rotated around a steering shaft by the thrust of a small ball rolling in the groove.
