する。FIG. 3 shows a second embodiment of the present invention in a manner similar to FIG. 3 are given the same numerals as the corresponding elements in FIG. 1, and a dash (') is added thereto. The main difference between the second embodiment and the first embodiment described above is that during the axial movement of the sleeve-shaped member 6 ′, the inner flange 2 ′ is too short to abut against the inner ring 2. The point is that it extends. This is because the shaft A 'has a large diameter portion at the left portion shown in FIG. 3 to the extent that the outer peripheral surface of the bearing inner ring 2 has a smaller diameter than the left portion of the shaft A'. It is because of that. An additional ring 14 is arranged on the shaft A 'between the left end of the inner ring 2 and the second flange 11' of the sleeve member 6 'to allow the flange 11' to move with respect to the bearing inner ring 2. ing. This ring 14 is a shaft body A '
Has an outwardly directed flange 15 that extends radially upward beyond the large diameter portion of the outer diameter. As described with reference to the sleeve-shaped member 6 of FIG. 1, when the sleeve-shaped member 6 'is moved rightward in FIG. 3, the second flange 11' comes into contact with the flange 15 of the ring 14, which is indirect. And the bearing inner ring 2 is engaged.

Is attached. The embodiment of FIG. 4 differs from the embodiment of FIG. 1 mainly in that the sleeve 6 ″ does not have an outwardly facing flange, and the hole 9 ″ is on the right of the sleeve 6 ″. Is formed in such a manner as to penetrate from left to right. Further, the left end surface of the sleeve-shaped member 6 "is in contact with the radial wall surface 8" of the housing H ".
