To provide a clearance regulator capable of easily removing a ratchet gear of an automatic clearance regulation mechanism, and a unit brake.SOLUTION: A clearance regulator 40 comprises: a ratchet gear 41 that is attached to a sheath rod for transmitting force to a brake shoe, and interlocks with the rotation of the sheath rod; a ratchet claw 42 that meshes with the ratchet gear 41, and restricts the rotation of the ratchet gear 41 in only one direction; and a frame body 50 to which the ratchet claw 42 is attached, and that covers the periphery of the ratchet gear 41. The clearance regulator adjusts a clearance between the brake shoe and a wheel. The frame 50 comprises an opening 55 having an opening width W longer than an outer diameter D of the ratchet gear 41, and a tension spring 54 that positions the ratchet claw 42 in the opening 55 and opens and closes the opening 55 by an external force.SELECTED DRAWING: Figure 5
【課題】自動隙間調整機構のラチェット歯車の取り外し作業が容易である隙間調整器及びユニットブレーキを提供する。【解決手段】隙間調整器40は、制輪子に対して力を伝達するさや棒に取り付けられ、さや棒の回転に連動するラチェット歯車41と、ラチェット歯車41に噛み合いラチェット歯車41の一方向のみの回転を規制するラチェット爪42と、ラチェット爪42が取り付けられ、ラチェット歯車41の周囲を覆う枠体50とを備え、制輪子と車輪との隙間を調整する。枠体50は、ラチェット歯車41の外径Dよりも長い開口幅Wを有する開口部55と、開口部55にラチェット爪42を位置させ外力によって開口部55を開閉する引張ばね54とを備える。【選択図】図5
