PROBLEM TO BE SOLVED: To provide a check valve for a negative booster capable of suppressing variation of valve opening performance.SOLUTION: A check valve includes a housing 26 including a valve seat 33a, an annular seal member 37 serving as a valve body, and a seal support member 38 to which the seal member 37 is attached, and that has a flange part projecting in an outer diameter direction with respect to the seal member 37 at the back of the seal member 37. In a seating state, a clearance g between the flange part and an inner peripheral wall of the housing 26 becomes minimum.SELECTED DRAWING: Figure 3
