Estimating the term…
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).
A seal structure for a member-passing-through hole of a metal partition member wherein:
A seal structure for a member-passing-through hole of a metal partition member comprising:
A seal structure for a member-passing-through hole formed in a metal partition member for causing a member having an axial length greater than the thickness of said metal partition member and rigidity to pass through said hole and sealing the hole by a seal member, wherein:
A seal structure for a member-passing-through a round hole formed in a metal partition member, said metal partition member isolating an inside region from an outside region and defining the inside region to be tightly closed, and said seal structure being used for sealing the hole formed in said metal partition member and through which a member passes from the inside region to the outside region, said member having an axial length greater than the thickness of said metal partition member and rigidity, said seal structure further being used for fixing said member in said hole, comprising:
A seal structure for a member-passing-through round hole of a metal partition member, said metal partition member isolating an inside region from an outside region and defining the inside region to be tightly closed, comprising:
A seal structure for a member-passing-through round hole of a metal partition member, said metal partition member isolating an inside region from an outside region and defining the inside region to be tightly closed, comprising:
