Abstract
An inner diameter of a cylindrical portion of a metal core is set to such a value that the cylindrical portion is fitted to an outer ring by interference fit. An inner periphery of an end portion of the cylindrical portion of the metal core is larger in diameter than an inner periphery of a portion of the cylindrical portion, which is fitted to the outer ring. An elastic seal has a cylindrical portion that is in close contact with an outer periphery of the cylindrical portion of the metal core, and a folded-back portion that extends from the cylindrical portion. The folded-back portion is compressively deformed by being sandwiched between the inner periphery of the end portion of the cylindrical portion of the metal core and the outer periphery of an outer ring.
