徴とするキヤスター。 In a caster in which a wheel frame on which a wheel is pivotally supported is rotatably assembled to a caster mounting plate via a steel ball, a cylindrical shaft part recessed downward is formed in the caster mounting plate, and the shaft part A recessed cylindrical bearing part into which the mounting plate is fitted is formed on the upper part of the wheel frame, and steel balls are interposed at two places: the upper surface of the wheel frame on the upper outer periphery of the bearing part and the upper surface of the bottom part of the bearing part. The caster is characterized in that the wheel frame is rotatably locked to the shaft by fitting the shaft into the bearing of the wheel frame, and protruding the bottom end of the shaft from the bottom surface of the bearing and crimping outward.
