A housing of a high-pressure pump defines a passage communicating with a pressurizing chamber in which fuel is pressurized. The passage has an annular engagement groove which is radially outwardly concaved on its inner wall surface. A valve body is disposed in the passage. The engaged member is disposed inside of the passage wall. A valve body engaging member is comprised of a plurality of arc-shaped plate members, which form circular shape. The valve body engaging member is inserted into the engagement groove in such a manner as to be engaged with the valve body. A C-ring is firmly in contact with the plate members and biases them toward the engagement groove.
