PROBLEM TO BE SOLVED: To provide a bicycle liquid pressure brake device in which a brake failure due to an increase in temperature of brake liquid is avoided.SOLUTION: This invention relates to a bicycle liquid pressure brake device 100 that is operated in such a way that when an operator holds a brake lever H, brake liquid flows from an oil supply part 1 in one direction to an oil chamber 22 of a liquid pressure cylinder part 2, a piston lever 21 at the liquid pressure cylinder part is pushed out due to an increased pressure in the oil chamber to a pushing-out position, a brake part 4 cooperates with the piston lever and moves to a braking position to be braked. When the operator releases the brake lever, the brake liquid flows in one direction from the oil chamber of the liquid pressure cylinder part to an oil storage tank 3, the piston lever is returned from the pushing-out position to a drawing-in position and the brake liquid flows in one direction from the oil storage tank to the oil supply part through the cycle check valve 311.SELECTED DRAWING: Figure 1

    【課題】ブレーキ液の温度が上昇することで起こるブレーキ故障を避けるための自転車の液圧ブレーキ装置を提供する。【解決手段】自転車の液圧ブレーキ装置100であって、ブレーキレバーHを握る時、ブレーキ液が給油部1から片方向に液圧シリンダ部2の油室22へ流動し、油室の昇圧により液圧シリンダ部のピストンレバー21が押し出し位置へ押し出され、ピストンレバーによってブレーキ部4が連動して制動位置に移動することにより制動され、ブレーキレバーを放す時、ブレーキ液が液圧シリンダ部の油室から片方向に貯油タンク3へ流動し、ピストンレバーを押し出し位置から引き込み位置に戻し、且つ、ブレーキ液が貯油タンクからサイクル逆止弁311を通じて片方向に給油部へ流動する。【選択図】図1
