PROBLEM TO BE SOLVED: To provide a locking device of casters for a bag, which has a simple structure, is reduced in the number of components, facilitates assembling, and thereby can be manufactured at a low cost.SOLUTION: A locking device of casters for a bag includes: a frame which is rotatably fitted to a fitting member to a bag bottom part and to which an axle is fixed; casters which are rotatably pivotally supported on both ends of the axle and in the peripheral surface of which multiple lock pin engagement parts are radially formed; a lock pin operating member arranged in a retractable manner along a guide unit formed in the frame and exposed to a frame surface; and an elastic member arranged in the guide unit and having restoring properties for energizing the lock pin operating member in a direction protruding from the frame surface. The locking device is characterized in that the lock pin operating member is pushed down against the energization force of the elastic member having the restoring properties to bring the lock pin into a caster rotation free state, and the lock pin operating member is pushed up by the energization force of the elastic member having the restoring properties to make the lock pin be engaged with a lock pin engagement part formed in a caster inner periphery to bring the lock pin into a caster rotation lock state.SELECTED DRAWING: Figure 1
【課題】構造が簡単で、部品数が少なく、組み立てが容易で低コストで製造が可能なカバン用キャスターのロック装置を提供することを目的とする。【解決手段】カバン底部への取付部材に対して回転自在に取り付けられ車軸を固定したフレームと、車軸の両端に回転自在に軸支され内周面にロックピン係合部を複数放射状に形成したキャスターと、フレームに形成したガイド部に沿って出没自在に配置されフレーム表面に露出するロックピン作動部材と、ガイド部に配置されロックピン作動部材をフレーム表面から突出する方向に付勢する復元性を有する弾性部材と、を備え、ロックピン作動部材を復元性を有する弾性部材の付勢力に抗して押し下げてロックピンをキャスター回転フリーの状態とし、ロックピン作動部材を復元性を有する弾性部材の付勢力により押し上げてロックピンをキャスター内周に形成したロックピン係合部と係合させキャスター回転ロック状態とすることを特徴とする。【選択図】 図1
