PROBLEM TO BE SOLVED: To solve the problem that a conventional structure requires a large number of components, cannot show the optimum vibration relaxation, and cannot achieve precise suppression means of vibration, against component damage or abnormal sound production caused by impact force generated when traveling along an irregular traveling road surface at faster speed than walking.SOLUTION: In a buffer caster 101, axle support and revolution support are constituted integrally, in which the axle support is carried out through a buffer 3 interposed between an axle 2 and a revolving frame 5, and the revolution support is carried out through a revolving slide plate 6 interposed between the revolving frame 5 and a stationary frame 7.SELECTED DRAWING: Figure 2
【課題】本発明の課題は、凹凸走行路面を歩行より早い速度で走行した時の衝撃力による部品破損や異音発生に対し、従来の構造では、部品点数が多く、最適な振動緩和が発揮できず、的確な振動の抑制手段が実現できていない点である。【解決手段】車軸2と旋回フレーム5との間に緩衝体3を介して車軸支持し、旋回フレーム5と固定フレーム7との間に旋回摺動板7を介して旋回支持を行い、車軸支持と旋回支持を一体に構成した緩衝キャスター101とする。【選択図】 図2
