PROBLEM TO BE SOLVED: To provide a tread brake device enabling space saving, and also capable of adjusting an interval between a tread and a brake shoe, with a simple structure.SOLUTION: An interval adjustment mechanism 5 of a tread brake device is configured such that when a push rod 3 advances to a braking side beyond a preset advance amount, an adjustment unit 31 returns to an initial position as moved by a predetermined amount to an evacuation side opposite to the braking side with respect to the push rod 3; while a drive nut 30 is pushed, relative rotation between itself and the push rod 3 is regulated, and while the drive nut is not pushed, it relatively rotates to the push rod 3, to thereby return to an initial position as moved by a predetermined amount to the evacuation side.SELECTED DRAWING: Figure 2

    【課題】省スペースを達成しつつ、簡易な構成で踏面と制輪子との隙間の調整が可能な踏面ブレーキ装置を提供する。【解決手段】踏面ブレーキ装置の隙間調整機構5では、調整部31は、押棒3が予め設定された進出量を超えて制動側に進出したときに、押棒3に対して制動側とは反対側の退避側に所定量だけ移動した状態のまま初期位置に戻り、駆動ナット30は、押されている間は押棒3との間の相対回転が規制され、押されていない状態となった際には、押棒3に対して相対回転することで、退避側に所定量だけ移動した状態のまま初期位置へ戻る。【選択図】図2
