1. A sealing device for sealing an annular gap between a shaft and a housing rotating relative to each other, comprising:
an elastomeric seal having a seal lip that is in slidable contact with a surface of the shaft; and a support member supporting an inner peripheral surface side of the elastomeric seal at a position on an opposite side of the seal lip from a sealed liquid side, wherein the support member is configured from a stepped annular member having a small diameter portion on the sealed liquid side and a large diameter portion on the opposite side from the sealed liquid side intervened by the small diameter portion, the large diameter portion being larger in outer diameter than the small diameter portion, and the elastomeric seal has an interference with an inner peripheral surface of a shaft hole of the housing and an interference with each of the small diameter portion and the large diameter portion, and is fixed in a state in which the elastomeric seal is press-fitted in between the inner peripheral surface of the shaft hole and the support member. |
