To suppress that a distance between base end portions of a pair of rotary arms becomes short.SOLUTION: A clearance adjusting mechanism 70 in a brake device 10 is equipped with a male screw portion 71. A female screw portion 72 is fitted in the male screw portion 71. The female screw portion 72 is attached with an input member 73 that relatively rotates the female screw portion 72 in one direction with respect to the male screw portion 71. In the clearance adjusting mechanism 70, when the female screw portion 72 relatively rotates in one direction with respect to the male screw portion 71, a distance between the base end portions of the pair of rotary arms 40 become long. Furthermore, the clearance adjusting mechanism 70 is equipped with a one-way clutch 75 that permits relative rotations of the female screw portion 72 in one direction with respect to the male screw portion 71, and regulates the relative rotations of the female screw portion 72 in the other direction with respect to the male screw portion 71.SELECTED DRAWING: Figure 6
【課題】一対の回転アームの基端部間の距離が短くなることを抑制する。【解決手段】ブレーキ装置10における隙間調整機構70は、雄ねじ部71を備えている。雄ねじ部71には、雌ねじ部72が嵌め込まれている。雌ねじ部72には、雌ねじ部72を雄ねじ部71に対して一方の方向に相対回転させる入力部材73が取り付けられている。隙間調整機構70では、雌ねじ部72が雄ねじ部71に対して一方の方向に相対回転したときに一対の回転アーム40の基端部同士の距離が長くなる。さらに、この隙間調整機構70は、雄ねじ部71に対する雌ねじ部72の一方の方向への相対回転を許容しつつ、且つ、雄ねじ部71に対する雌ねじ部72の他方の方向への相対回転を規制するワンウェイクラッチ75を備えている。【選択図】図6
