Abstract
A sealing apparatus includes a reinforcing ring, an elastic body portion formed of an elastic body having conductivity, and a conductive grease. The elastic body portion includes a base portion, a lip portion which extends from the base portion, and a tension force applying member which is an elastic member in an annular shape. The tension force applying member is mounted on an outer peripheral side of the lip portion at a lip tip end portion to apply a tension force which presses a lip contact end against an outer peripheral surface of a shaft. The conductive grease is applied to at least a portion of an inner peripheral surface of the elastic body portion which faces an inner periphery side.
