摘要： PROBLEM TO BE SOLVED: To solve problems that a confining region for confining a hydraulic fluid is generated in a meshing part of gears, and vibration and noise are generated due to a sudden pressure change in the hydraulic fluid in the confining region in a gear pump. SOLUTION: This gear pump is provided with a recessed part 18 composed of a hole extending in the radial direction from tooth bottom parts 7c and 8c of the respective gears 7 and 8. The confining region 19 generated between meshing points A and B of the driving gear 7 and the driven gear 8 becomes the volume including the volume of the recessed part 18 for communicating with this region. A rate of change of the volume of the confining region 19 is reduced by increasing the volume of the confining region 19 by the recessed part 18. The pressure change in the confining region 19 is relieved to prevent the generation of the vibration and noise.
