を特徴とする、自転車用ハブのシール構造。[Scope of Claim for Utility Model Registration] A hub body having a ring on the inner periphery of the large diameter portion formed at both ends of a central through-hole is placed between the pair of left and right cones screwed onto the hub shaft and the ring. In a bicycle hub formed by rotatably supporting a hub axle by rollingly interposing a plurality of steel balls, the inner periphery of the outermost part of the large diameter part and the outer periphery of the cone The seal structure seals a gap, and includes a cylindrical base having an outer diameter that can be press-fitted into the large diameter portion, and an inner periphery of the cylindrical base from one end in the axial direction that can be located close to the outer periphery of the cone. and a locking flange extending radially inward from the other axial end of the cylindrical base. In between, a donut disc-shaped second seal member having an outer diameter slightly larger than the inner diameter of the locking flange and an inner diameter that can be tightly fitted to the outer periphery of the cone is elastically expanded by the first seal member. By press-fitting the cylindrical base of the first seal member into the seal body, which has been engaged and held in advance by increasing the diameter or elastically contracting the diameter of the second seal member, the inner periphery of the large diameter portion of the hub body is inserted. For a bicycle, the second seal member is fixed to the outer periphery of the cone by tightly fitting the inner periphery to the outer periphery of the cone that is screwed onto the hub shaft. Hub seal structure.
