ブ。 A boss part is formed protruding from one side of the valve body in which the port is bored, and a check plate that opens and closes the port to communicate and block the flow of liquid is fitted onto the outer periphery of this boss part so as to be movable in the axial direction. A holding member is provided at the tip of the boss portion to support a check spring that biases the check plate in the valve closing direction, and to restrict the maximum valve opening position of the check plate before the check spring reaches a close contact state. A check valve characterized by:
