Claims

[Scope of utility model registration request]

A rotating shaft with vanes protruding outward in the radial direction is fluid-tightly inserted into a casing with vanes protruding in the inward radial direction, and high-pressure fluid is supplied to one side of the pressure accumulation space partitioned by the two vanes to the other side. A rotary actuator configured to output torque by supplying low-pressure fluid to each rotary actuator, characterized in that a pressure accumulation space is divided into three or more parts in the axial direction via a partition disk.
