Abstract
A sealing member seals a space between a pin and a movable pin device. The movable pin device is aligned with a panel in an axial direction with a space between the movable pin device and the panel. The pin is through the panel and the movable pin device along an axis and is reciprocable in the axial direction. The sealing member includes a first annular portion including a first sealing flange to seal a space between the first sealing flange and the movable pin device, and a second annular portion to come in contact with the pin in a slidable manner. The first annular portion further includes a protruding portion located farther than the first sealing flange in the first direction to come in contact with the panel.

A sealing member for sealing a space between a penetrator and a second structure, the second structure being aligned with a first structure on an axis extending in an axial direction with a space between the second structure and the first structure, the penetrator being through the first structure and the second structure along the axis and being reciprocable in the axial direction, the sealing member comprising:
- a first annular portion to come in contact with the second structure, the first annular portion including a first sealing flange to seal a space between the first sealing flange and the second structure;
- a second annular portion to come in contact with the penetrator in a slidable manner;
- and
- a connecting portion connecting ends of the first annular portion and the second annular portion, the ends being located in a direction opposite to a first direction from the second structure to the first structure parallel to the axial direction,
- wherein the first annular portion further includes a protruding portion located farther than the first sealing flange in the first direction to come in contact with the first structure.
A sealing member, comprising:
- a first annular portion located about an axis, the first annular portion including, at an end of the first annular portion in a first direction along the axis, a first sealing flange protruding radially outward;
- a second annular portion spaced and radially inward from the first annular portion;
- a connecting portion connecting ends of the first annular portion and the second annular portion, the ends being located in a direction opposite to the first direction;
- and
- a protruding portion located farther than the first sealing flange in the first direction, the protruding portion having a first distance between a center of thickness of the protruding portion and the axis, the first distance increasing in the first direction.
