<p>PROBLEM TO BE SOLVED: To secure hinge stiffness at the side part which turns out to be a leading side in the swash plate rotating direction of a hinge arm connection part, and stabilize the rotational balance of a rotation assembly. SOLUTION: Out of the forked hinge arms 21 of a journal connected with the hinge arm 19 of a drive plate by a pin 23, since the pin engaging length L2 of a hinge arm 21B which is turned out to be a trailing side in the rotating direction of a swash plate, is made smaller than the pin engaging length L1 of an hinge arm 21A which is turned out to be a leading side, hinge stiffness at the aforesaid leading side can thereby be secured, and concurrently, the hinge portion can be reduced in mass, so that the rotational balance of a rotation assembly can thereby be stabilized.</p> |
