[0179] Figure 8 A second embodiment of the present invention is shown.
[0180] In the first embodiment, an embodiment in which the circumferential groove 73 is provided on the outer diameter of the inner ring 33 constituting the sliding contact area with the piston 43 and the lubricant holding portion 71 is formed between the inner diameter of the piston 43 is described. However, in this embodiment, the inner surface (guide surface) of the short cylindrical portion 43d of the piston 43 includes a circumferential groove 73, and a lubricant holding portion 71 is formed in a sliding contact area with the outer diameter of the inner ring 33. In the present embodiment, the lubricant holding portion 71 is constituted by including three circumferential grooves 73 .
[0181] In addition, the circumferential groove may be one circumferential groove, or may be composed of two or four or more independent circumferential grooves. In addition, it is within the scope of the present inve...

[0184] Figure 9 to Figure 14 A third embodiment of the present invention is shown.
[0185] In the first embodiment, instead of the fitting hole 7i provided in a recessed state in the center region of the lower surface 7b of the mounting part 7, the end of the rod 3a is integrally molded with a nut part 60 so that it can be directly tightened.
[0186] In addition, instead of the piston 43 having the above-mentioned configuration, the piston may be an embodiment in which the outer ring 57a constituting the bearing unit 57 is also used. Furthermore, in the present embodiment, the lubricant holding portion 71 is formed in the sliding contact region between the outer ring 57a and the inner ring 33 (see Figure 9 to Figure 12 ).
[0187] The bearing device 57 employs a thrust angular ball bearing (bearing device) 57 similarly to the first embodiment, but in this embodiment, the outer ring 57a also serving as a piston is configured as follows.
[0188] The outer ring 57a accomm...
