Claims

[Scope of utility model registration request]

The side surface of the body is closed with a closing member such as a mounting flange or a cover, and a pair of winding bushing press-fit holes are formed in this closing member, and the gear shaft is rotatably supported by the winding bushings press-fitted into the press-fitting holes. A pressure member such as a side plate is placed along the side surface of the gear, a seal groove is formed on the back surface of the pressure member, and a loading area is defined on the back surface of the pressure member by the seal member attached to the seal groove. In a gear pump or motor, a circular stepped portion is formed around the opening of the winding bushing press-fit hole formed in the closing member, and is concentric with the press-fit hole, and both stepped portions are formed on a line connecting the centers of the gear shafts. A continuous linking groove and a dividing groove guiding the end of the seal member toward the body bore side are formed, and the tip of the winding bushing press-fitted into the press-fitting hole is made to protrude further forward than the circular step portion. A gear pump or motor in which the and winding bushings together form a sealing groove, and a sealing member and an isolation plate are attached to the sealing groove.
