The charge relief valve includes a relief valve body provided with a large diameter hole, a small diameter hole, and a check valve seat formed between the large diameter hole and the small diameter hole. The large diameter hole is provided with a check valve body which is seatable on the check valve seat and is movable in the axis line direction, and a slip-out prevention member for preventing the check valve body from being separated from the large diameter hole while allowing the check valve body to selectively communicate or block between the large diameter hole and the small diameter hole.
