An outlet valve which is formed between a sleeve housing and an outlet valve cover of a piston pump of a vehicle includes: a ball which is movably disposed between the sleeve housing and the outlet valve cover and selectively opens/closes a discharge hole which is formed in the sleeve housing depending on a movement thereof; and a ball biasing member which exerts a force to urge the ball to move a position where the discharge hole is closed. The ball biasing member is formed such that an oil discharge passage for discharging an oil discharged via the discharge hole to an outside is formed between the sleeve housing and the outlet valve cover.
