To provide a brake mechanism for a universal caster capable of braking a wheel of a traveling vehicle to decelerate or lock the wheel with little force.SOLUTION: A universal caster is provided which is to be attached under a baseplate of a vehicle and which can roll and rotate a wheel 13. A vertical shaft 3 is inserted and attached in a vertically movable manner via a bearing body 2 provided in the center of an attachment seat 1 of the universal caster. A brake shoe attachment body 4 for attaching a brake shoe 8 to the lower end of the vertical shaft 3 is rotatably attached via a rotation shaft 5 and a shaft 7 laterally bridging a wheel support frame 6. An arm 11 having a cam 10 is rotatably attached to the attachment seat 1 at the upper end of the vertical shaft 3. The wheel 13 and the brake shoe 8 are brought into press-contact with each other by rotating the arm 11.SELECTED DRAWING: Figure 1
【課題】小さな力で走行中の車両の車輪にブレーキを掛けて減速やロックをすることのできる自在キャスターのブレーキ機構の提供。【解決手段】車両の台板下部に取付ける車輪13の回転と旋回が可能な自在キャスターの取付け座1の中心に設けた軸受け体2を介して昇降可能に上下軸3を挿通して取付けて、上下軸3の下端にブレーキシュー8を取付けるためのブレーキシュー取付け体4を旋回軸5および車輪支持枠6に横架したシャフト7を介して回動可能に取付けてあり、上下軸3の上端にカム10を備えたアーム11を回動可能に取付け座1に取付け、アーム11を回動することにより車輪13とブレーキシュー8を圧接する。【選択図】図1
