摘要： A hydraulic pump includes a case having a plurality of fluid paths and a cylinder-shaped groove with a shaft-bearing hole. A shaft is inserted into the shaft-bearing hole of the groove such that the shaft is rotated. A cylinder block is disposed in the groove of the case with a plurality of cylinders such that the cylinder block is rotated upon receipt of a rotational power of the shaft. The cylinder block has a barrel-shaped bottom portion surrounding the shaft. A piston is inserted into each of the cylinders such that the piston reciprocates. A swash plate is combined with the case such that the swash plate covers an opening portion of the groove. The swash plate has an inclined side facing the cylinder block. A shoe has a top side, a bottom side and a stepped middle portion. The top side of the shoe is connected to the piston via a connecting member. The bottom side of the shoe contacts the inclined side of the swash plate. An elastic shoe holder is held between the barrel-shaped bottom portion of the cylinder block and the stepped middle portion of the shoe to compress the shoe against the inclined side of the swash plate.
