In a gear pump or motor, a second high-pressure area is provided at a position corresponding to the rotational position of the gear where the pressure in the tooth groove changes drastically depending on the rotational speed, and the second high pressure area communicates with the tooth groove passing through the second high pressure area. A cup-shaped seal is fitted to define the second high-pressure area, and the inside of the cup-shaped seal is formed into a concave arc surface that coincides with the outer peripheral surface of the wound bushing inserted into the bushing. A gear pump or motor whose arcuate surface follows the circumference of a wound bush that protrudes outward from the bush.
