Abstract
A sealing device includes a first sealing member and a second sealing member that are mounted on a housing, the outer peripheral surface of the rotational shaft being in slidable contact with the first sealing member and the second sealing member. Distal portions of multiple first hooks formed on the first sealing member are hooked on the distal portions of multiple second hooks formed on the second sealing member for restricting movement of the second sealing member away from the first sealing member in the axial direction of the sealing device. Distal portions of multiple first stoppers formed on the first sealing member are in contact with the distal portions of multiple second stoppers formed on the second sealing member for restricting movement of the second sealing member toward the first sealing member in the axial direction.
