PURPOSE:To make vibration compelling force very small by enabling an inside slot member to axially slide in relation to an outside guide slot and intercepting axial vibration compelling force, which is caused by frictional force, inside a joint. CONSTITUTION:An axial relative displacement between an inside axial member 13 and an outside axial member 15 shows that a roller 14 rolls along the cylindrical inside guide slot 16a of an inside slot member 16 as the roller 14 is rolling around a trunnion axis 12. And it is allowed with very small slide friction that the inside slot member 16 slides through a low frictional means 18 along the outside guide slot 15a of an outside axial member 15. Accordingly, vibration compelling force in the direction of an outside axial member which is caused by frictional force produced between the trunnion axis 12 and the roller 14 is intercepted by a slide with low friction between the inside slot member 16 and the outside axial member 15, and the vibration compelling force output in the outside of a joint becomes very small. |
