Claim 0:
1. A sealing device for sealing an annular space formed by a plurality of members, the sealing device comprising:
a reinforcing ring formed annularly around an axis; and
an elastic body part that is formed from an elastic body attached to the reinforcing ring and that is formed annularly around the axis, the reinforcing ring including:
a tubular portion having a cylindrical shape around the axis; and
a flange projecting annularly from an outer end portion of the tubular portion to an inner periphery side,

wherein the elastic body part includes an elastic tubular portion that covers the tubular portion of the reinforcing ring and a lip portion that is an annular portion covering the flange from an outer side, the lip portion projecting from the flange toward the outer side in a direction of the axis and projecting toward the inner periphery side in a radial direction, the lip portion including:
a seal lip portion that is an annular portion projecting toward the outer side in the direction of the axis; and
a secondary lip portion that is an annular portion projecting toward an inner side in the direction of the axis,
both the seal lip portion and the secondary lip portion are positioned radially inward of the flange,
wherein the seal lip portion and the elastic tubular portion protrude axially in opposite directions from the flange; and
wherein, in the direction of the axis, the secondary lip portion is closer to the flange than the seal lip portion.
