Abstract:
A sealing structure includes a hub, an outer-periphery-side mass body, an outer-periphery-side damper elastic body, an inner-periphery-side mass body, and an inner-periphery-side damper elastic body. The hub is attached to one end of a rotary shaft of an object to be attached. The oil seal includes a seal lip in an annular shape and a side lip in an annular shape and is oriented to the inner-periphery-side mass body, is attached in a through hole in the object to be attached, and hermetically seals a void between the hub and the object to be attached. The inner-periphery-side mass body forms at least a part of a pocket which is composed of a recessed portion in an annular shape, and the side lip forms a labyrinth seal which is composed of a gap in an annular shape between the side lip and the pocket.

Claim (Index 1):
A sealing structure with a damper and an oil seal, wherein\n the damper includes a hub, an outer-periphery-side mass body in an annular shape which is provided on an outer periphery side of the hub and is centered about an axis, an outer-periphery-side damper elastic body which is disposed between the hub and the outer-periphery-side mass body and elastically connects the hub and the outer-periphery-side mass body, an inner-periphery-side mass body in an annular shape which is provided on an inner periphery side of the hub and is centered about the axis, and an inner-periphery-side damper elastic body which is disposed between the hub and the inner-periphery-side mass body and elastically connects the hub and the inner-periphery-side mass body, the damper is attached to one end of a rotary shaft of an object to be attached in a state in which the hub is inserted through a through hole in the object to be attached, the oil seal is attached in the through hole in the object to be attached in a state of inclusion of a seal lip in an annular shape which is centered about the axis and a side lip in an annular shape which is centered about the axis and is oriented to the inner-periphery-side mass body and seals between the hub and the object to be attached, the hub includes a boss portion in an annular shape which is centered about the axis, a rim portion in an annular shape which is located on the outer periphery side of the boss portion and is centered about the axis, and a disk portion in a disk shape which connects the boss portion and the rim portion and is centered about the axis, the outer-periphery-side mass body is attached to an outer peripheral surface of the rim portion via the outer-periphery-side damper elastic body, the inner-periphery-side mass body is attached to an inner peripheral surface of the rim portion via the inner-periphery-side damper elastic body, the inner-periphery-side mass body forms at least a part or a whole of a pocket which includes a recessed portion in an annular shape centered about the axis, and the seal lip of the oil seal slides on the boss portion, and the side lip of the oil seal extends toward the pocket to form a labyrinth seal which includes a gap in an annular shape between the side lip and the pocket.
