Abstract
A seal structure in which a hole (5) is defined by a metal base member (4) as a partition member for partitioning the regions on the opposite sides thereof to a gas tight or liquid tight state and a member passes through the hole (5) and extends therefrom. The member passing through the hole (5) may be an electric conductor (2), a pipe member for flowing gas or liquid, a heat pipe for flowing a heat medium, an optical fiber for transferring an optical signal, or the like, and the structure is arranged such that the member passing through the hole is disposed through a synthetic resin seal member (3) and the hole (5) is sealed based on the confinement effected by the plastic deforming action of the base member (4) and the deforming action of the seal member (3) effected by making use of the elastic plasticity thereof, whereby the structure exhibits an excellent pressure resistive performance and can effectively seal the hole (5).
