Document Type and Number:
WIPO Patent Application WO/2023/008181
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sealing device capable of achieving long-term electrical conductivity between a rotary shaft and a housing at low cost and in a space-saving manner. The problem is solved by a sealing device that is disposed in and seals a gap between an outer surface of a rotary shaft and an inner surface of a housing having a shaft hole into which the rotary shaft is inserted, the inner surface forming the shaft hole, and that can provide electrical conductivity between the housing and the rotary shaft pressed against the inner surface of the housing forming the shaft hole when the rotary shaft rotates.
