Abstract
A hub includes a hub housing sleeved rotatably on a spindle, and a tubular end piece sleeved fixedly on the spindle. A tubular flexible seal member is disposed between the hub housing and the end piece, and includes an outer ring and an inner ring. The outer ring has a circular tubular portion with an axial inner end, and an inward flange that extends integrally, radially and inwardly from the inner end of the circular tubular portion to abut against a bottom wall of an annular groove that is formed in an end surface of the hub housing. The inner ring has a largest-diameter inner end that is formed integrally with an inner periphery of the inward flange, and a smallest-diameter outer end portion which is sleeved around and which is in tight engagement with a frictional outer surface of an insert portion of the end piece. The inner ring reduces gradually in inner diameter from the largest-diameter inner end to the smallest-diameter outer end portion. The smallest-diameter outer end portion has an inner diameter that is slightly smaller than outer diameter of the insert portion of the end piece when removed from the end piece.
