To provide a rotary swash plate-type hydraulic pump capable of suppressing variation in pressure loss generated in a hydraulic fluid, for each cylinder bore.SOLUTION: A rotary swash plate-type hydraulic pump includes: a casing provided with a suction passage; a cylinder block disposed in the casing in a manner of being not relatively rotatable and provided with a plurality of cylinder bores connected to the suction passage; a plurality of pistons each inserted to each of the plurality of cylinder bores; and a rotary swash plate housed in the casing rotatably around an axis and reciprocating each of the pistons. The suction passage has a plurality of suction ports to which a hydraulic fluid is sucked.SELECTED DRAWING: Figure 1 【課題】作動液に生じる圧力損失に関してシリンダボア毎のばらつきを抑制することができる回転斜板式液圧ポンプを提供する。【解決手段】回転斜板式液圧ポンプは、吸入通路が形成されるケーシングと、ケーシング内に相対回転不能に配置され、吸入通路に繋がる複数のシリンダボアが形成されるシリンダブロックと、複数のシリンダボアの各々に挿入される複数のピストンと、ケーシング内に軸線周りに回転可能に収容され、ピストンの各々を往復運動させる回転斜板と、を備え、吸入通路は、作動液が吸入される複数の吸入ポートを有する、【選択図】 図１
