Abstract
A sealing device capable of maintaining an electrically conductive performance relative to even an inner peripheral member rotating at a high speed. The sealing device includes an electrically conductive elastic body unit that is an annular member and that includes a portion made of an elastic material with electrical conductivity. The electrically conductive elastic body unit is able to come into contact with a shaft of an electric motor and a housing. The electrically conductive elastic body unit is able to form an electrically conductive circuit between the shaft of the electric motor and the housing. An impedance of the electrically conductive circuit during a rotation of the shaft of the electric motor at a circumferential velocity of 60 m/s or less is in a range from 0.01Ω to 100Ω.
