To provide a low cost and simple snow resistant braking structure.SOLUTION: A simple snow resistant braking structure applying hydrostatic pressure from a hydrostatic pressure source to a brake cylinder driving a brake block, includes: a first flow passage connecting the hydrostatic pressure source to the brake cylinder; an on-off valve for turning on and off the first flow passage; a second flow passage connected in parallel to the first flow passage; a check valve provided in the second flow passage and allowing flow from the hydrostatic pressure source side to the brake cylinder side; a third flow passage connected in parallel to the first flow passage; and a relief valve provided in the third flow passage.SELECTED DRAWING: Figure 1

    【課題】低コストで簡易な耐雪ブレーキ構造を提供する。【解決手段】制輪子を駆動させるブレーキシリンダに流体圧力源から流体圧を付与する簡易耐雪ブレーキ構造であって、前記流体圧力源を前記ブレーキシリンダに接続する第1流路と、前記第1流路を開閉する開閉弁と、前記第1流路に並列接続された第2流路と、前記第2流路に設けられ、前記流体圧力源側から前記ブレーキシリンダ側への流れを許容する逆止弁と、前記第1流路に並列接続された第3流路と、前記第3流路に設けられたリリーフ弁と、を備える。【選択図】図1
