モータ。A gear having a large diameter part and a small diameter part on the outer periphery, the gear having a tooth tip in sliding contact with the inner peripheral surface of the gear case to divide the inside of the gear case into a high pressure area and a low pressure area, and a gear having a large diameter part and a small diameter part on the outer periphery. In a gear pump or motor, the gear pump or motor includes a side plate for a side seal that fits into the inner periphery of the gear case and comes into sliding contact with the tooth side surface of the gear, near the boundary between the high pressure region and the low pressure region. At the boundary between the large-diameter part and the small-diameter part of the side plate, the shape of the side plate changes continuously in the direction of rotation of the gear to soften the pressure gradient from the low-pressure area to the high-pressure area. A gear pump or motor characterized by having a section.
