The invention relates to a sealing device. The sealing device comprises an annular elastic sealing body and a rigid annular piece, the elastic sealing body is arranged on the radial outer side of the rigid annular piece, the elastic sealing body comprises a base part and sealing lips, the sealing lips comprise a contact lip and a non-contact lip, the non-contact lip comprises a non-contact lip supporting part and a non-contact lip end part, and the non-contact lip supporting part is connected with the rigid annular piece. The non-contact lip support portion extends in the axial direction, and the non-contact lip end portion is provided on the non-contact lip support portion and extends radially outward. By the adoption of the sealing device, the structure can be more simplified, a large amount of cost can be saved, friction between the sealing device and a sealed component is lower, and the sealing performance is higher.
