  • Hermetically sealing device and hermetically sealing method
    Patent number: 11421811
    Abstract: A hermetically sealing device has a sealing main-body and a rubber seal adhered to the sealing main-body. The rubber seal includes an inner lip, a slit and an outer lip. The inner lip extends along a periphery of the bored opening, and includes an outer-circumference surface that extends forward and inclines toward an inner-circumference side. The slit is formed on an outer-circumference side relative to the inner lip. An outer-surface-side edge of the bored opening enters the slit. The outer lip is formed on an outer-circumference side relative to the slit that is formed on an outer-circumference side relative to the inner lip, and transforms in such a manner that the outer lip extends toward an outer-circumference side to be hermetically in contact with an outer surface of the periphery of the bored opening.
