Abstract

PURPOSE: To make a high-airtightness accurate seal possible by expanding an aperture part thermally and cooling the aperture part to contract it after fitting a cover material to the aperture part.
CONSTITUTION: Ring step part 4 is formed on the inside circumference of aperture part 3 of case 1, and circumference groove 5 is provided at the circumference edge of cover material 2, and seal material 6 consisting of half-setting-property, thermosetting-property or thermoplastic synthetic resin is inserted into circumference groove 5. Then, case 1 is first heated to expand aperture part 3 thermally so that aperture part 3 may be larger than cover material 2, and cover material 2 is put on ring step part 4. After that, when case 1 is cooled to contract aperture part 3 thermally, the circumference edge of cover material 2 is fitted to the inside circumference of aperture part 3 closely, and aperture part 3 is sealed hermetically. In this case, the seal dependent upon the adhesion force of seal material 6 which is inserted into circumference groove 5 of cover material 2 takes effect to make a high-airtightness seal possible.
