Abstract: A fourth pin that slides on a rotary shaft is provided to a swash plate. A guiding surface for guiding the fourth pin is provided to the rotary shaft. The fourth pin is guided by the guiding surface, the swash plate is supported by the rotary shaft via the fourth pin, and a force having a component in a direction orthogonal to the direction of movement of a movable body acting on the swash plate is thereby reduced.

As a result, when the inclination of the swash plate is changed, unwanted tilting of the movable body relative to the direction of movement is suppressed.
