The first framework may include a first radially extending part extending towards the inner ring, the second framework may include a second radially extending part extending towards the outer ring, and the second radially extending part may be located on an axially outer side of the first radially extending part. The sealing structure may form a first chamber and a second chamber in a radial direction, the first chamber being formed by the first or second radially extending part. The second chamber may be located on a radially inner side of the first chamber, and the elastic sealing member may include a first sealing member extending into the first chamber and a second sealing member extending into the second chamber.
