A sealing coating(17) is formed at the inner surface of the main body. The nozzle part is installed at one end part of the main body. The nozzle part discharges sealant. The plunger is installed on another inner surface of the main body. The first light shielding part surrounds the outer surface of the main body. The second light shielding part covers the nozzle part by covering the entire cross section of the one inner end part of the main body.
