Therefore, the present application people are clear by studying: the 2nd formed especially with rubber material (EPDM, EPM etc.)
It is deformed due to centrifugal force effect towards radial foreign side when axis device 40 rotates at work.More specifically, basal part 40A with
Radially become larger and is deformed along axial thinning mode.In addition, the top of tabling piece 40B from radial center towards foreign side to beat
The mode opened deforms.
Moreover, the 2nd shaft coupling 40 is embedding with the 1st shaft coupling 30 if the 2nd shaft coupling 40 deforms (when rotation) at work
Close chimerism, more specifically the 2nd tabling piece 40B of shaft coupling 40 and the supporting for the embeded slot 30A of the 1st shaft coupling 30 of part
