Patent ID: 7765821

Claim:
A seal device for sealing a through hole in a partition comprising: a first seal providing a first abutment portion that abuts against a periphery of the through hole in an entirety thereof; and a second seal providing a second abutment portion that is made of an elastic material abutting against an outer peripheral surface of a component disposed in the through hole, wherein the first seal and the second seal are connected to cover an entire space between the periphery of the through hole and the outer peripheral surface of the component, the component has a bent portion in the outer peripheral surface thereof, and the second seal has a support member with a higher elasticity relative to the second abutment portion on an outer side of the second abutment portion, the support member having an inner peripheral surface thereof shaped in a corresponding form of the outer shape of the component and having a bent facing section of the inner peripheral surface thereof shaped in a corresponding form of the bent portion of the component; wherein a section along a periphery of the second abutment portion forms an elongated protrusion that is bent by the component in a component insertion direction for abutting against the outer peripheral surface of the component, a rest of the periphery that substantially forms a remaining portion of the periphery of the second abutment portion forms a rib shape protrusion that is smaller than the elongated protrusion and is pressed in a substantially perpendicular direction relative to the component insertion direction for abutting against the outer peripheral surface of the component, and the elongated protrusion and the rib shape protrusion are connected with each other along the periphery at a morphing portion that gradually morphs respective cross sections of the rib shape protrusion and the elongated protrusion for interconnection.
