Abstract
A sealing device includes an elastic body configured to seal an annular gap between an inner member and an outer member in order to prevent a leak of an object through the annular gap. The elastic body includes an annular main body portion including a first end portion and a second end portion opposite to each other and being to be disposed in the annular gap with the first end portion being closer to the object than the second end portion, a seal lip portion extending from the first end portion and being to be in contact with the inner member, a flange portion extending outwardly from the second end portion and including a first side and a second side opposite to each other, a side lip portion extending from the second end portion in a direction away from the first end portion, and a projecting portion extending from the second side and circumferentially about the annular main body. The first side is to be closer to the object than the second side and to be in contact with the outer member. The projecting portion is located such that the projecting portion is not to be in contact with the side lip portion with a distal end portion of the side lip portion being tilted radially outwardly in response to a front surface of the side lip portion being pressed by a member.
