PROBLEM TO BE SOLVED: To provide a caster with a brake having a structure to obtain brake force by bringing a brake shoe (a side face part of a brake ring) into pressure contact with a proper place of a wheel.SOLUTION: An advancing/retracting pin 5, which moves vertically, is provided in a shaft member 3 in a penetrating state and is supported by an elastic body 14 in an upward direction at all times. Slide parts 6, 7, which are driven in back and forth directions of a wheel 4 by the vertical movement of the advancing/retracting pin 5, are provided below the shaft member 3. A pair of brake rings 8, 9, which is brought into pressure contact with the wheel 4 or released from the pressure contact in conjunction with the movement of the slide parts 6, 7, is provided in the slide parts 6, 7, respectively. The brake rings 8, 9 are biased in an opening/closing direction by the elastic body 14. A lower end part 5b of the advancing/retracting pin 5 is formed on an inclined surface having an angle to open and close the slide parts 6, 7. A reception part 16, in which the lower end part 5b of the advancing/retracting pin 5 is fitted, is formed in a portion where the slide parts 6, 7 face each other.SELECTED DRAWING: Figure 1
【課題】ブレーキシュー(ブレーキリングの側面部)を車輪の適所に圧接させて制動力を得る構成のブレーキ付きキャスターを提供する。【解決手段】軸部材3に、上下動する進退ピン5が貫通状態に設けられ、進退ピン5は弾性体14により常時上向き方向に支持されている。軸部材3の下に、進退ピン5の上下動により車輪4の前後方向へ駆動されるスライド部6、7が設けられ、各スライド部6、7に、スライド部6、7の移動に連動して車輪4へ圧接され又は圧接が解除される一対のブレーキリング8、9が設けられ、ブレーキリング8、9は弾性体14により開閉方向に付勢されている。進退ピン5の下端部5bは、スライド部6、7を開閉動作させる角度の傾斜面に形成され、進退ピン5の下端部5bが嵌まる受部16がスライド部6、7が向き合う部分に形成されている。【選択図】図1
