As described above, in this invention, the elastic seal can be attached by a simple operation of rotating the turnbuckle and tightening the wire, and
Since it is attached by mechanical tightening, the elastic seal can be attached extremely firmly and uniformly in the circumferential direction. In addition, the cylindrical part that is tightened by the wire rod and the seal lip are misaligned in the axial direction,
Since an annular groove is provided between the cylindrical portion and the seal lip, even if the cylindrical portion is deformed by tightening the wire, the seal lip will not deform. Therefore, the pressure force of the seal lip against the width of the outer ring will be reduced. A good sealing effect can always be obtained.
