| description | To provide a vehicular brake device which can inhibit leakage of a fluid in a reservoir when a fluid passage is damaged and inhibits a brake force from being generated by expansion of the fluid when a vehicle is not braked.SOLUTION: The vehicular brake device includes: an electric cylinder 2 which generates a fluid pressure according to a position of a piston 23, driven by an electric motor 22, in a fluid pressure chamber 24, formed in a cylinder 21, to compress wheel cylinders 81 to 84; a fluid passage 54 which connects the fluid pressure chamber 24 with a reservoir 45 through a port 211 formed at the cylinder 21; and a switch part 9 which allows the fluid in the fluid pressure chamber 24 to flow into the reservoir 45 through the fluid passage 54 in a specific state, in which the fluid pressure in the fluid pressure chamber 24 is excessive for a target pressure, and prevents the fluid to flow out through the fluid passage 54 in a normal state which is not the specific state.SELECTED DRAWING: Figure 1
【課題】液路が破損した際のリザーバ内のフルード漏れを抑制でき、且つ非制動時におけるフルード膨張による制動力の発生を抑制することができる車両用制動装置を提供する。【解決手段】本発明は、シリンダ２１内に形成された液圧室２４に、電気モータ２２によって駆動されるピストン２３の位置に応じた液圧を発生させてホイルシリンダ８１～８４を加圧する電動シリンダ２と、シリンダ２１に形成されたポート２１１を介して液圧室２４とリザーバ４５とを接続する液路５４と、液圧室２４の液圧が目標圧に対して過大である特定状態で液圧室２４のフルードの液路５４を介するリザーバ４５への流出を許容し、特定状態ではない通常状態で液路５４を介したフルードの流出を阻止する切替部９と、を備える。【選択図】図１ |
