To provide a brake operation device which can accurately detect operation of a brake pedal with a simple structure.SOLUTION: A brake operation device includes: pushers 19, 20 connected to a brake pedal 2; a fluid pressure mechanism 5 which is provided between the pushers 19, 20 and a pressing member 27 and transmits thrust force of the pushers 19, 20 to the pressing member 27 through fluid pressure; first elastic mechanisms 23a, 23b which generate elastic force in a direction such that the pushers 19, 20 are separated from the pressing member 27; a cylinder 18 which houses the pushers 19, 20 and restricts a retract end in the direction such that the pushers 19, 20 are separated from the pressing member 27; and a second elastic mechanism 37 which is provided at a position that enables the second elastic mechanism 37 to press the cylinder 18 to the pressing member 27 side and generates elastic force acting against the elastic force of the first elastic mechanisms 23a, 23b that separates the pushers 19, 20 from the pressing member 27.SELECTED DRAWING: Figure 1
【課題】簡単な構成によりブレーキペダルの操作を正確に検出することが可能な制動操作装置を提供する。【解決手段】ブレーキペダル2に連結されたプッシャー19,20と、プッシャー19,20と押圧部材27との間に設けられ、プッシャー19,20の推力を押圧部材27に液圧を介して伝達する液圧機構5と、プッシャー19,20を押圧部材27から離隔させる方向に弾性力を発生する第1弾性機構23a,23bと、プッシャー19,20を収容し、かつプッシャー19,20の押圧部材27から離隔する方向での後退端を規制するシリンダ18と、シリンダ18を押圧部材27側に押圧する箇所に設けられ、かつ第1弾性機構23a,23bにおけるプッシャー19,20を押圧部材27から離隔させる弾性力に抗する弾性力を発生する第2弾性機構37とを備えている。【選択図】図1
