車ポンプ。 A driven gear and a sintered metal drive gear that rotationally drives the driven gear are rotatably disposed inside a pump casing so as to mesh with each other and discharge liquid,
A portion of the drive shaft that is rotationally driven has a non-circular cross section that is fitted into a fitting hole that is formed with a non-circular cross section of the drive gear, and the fitting hole of the drive gear is fitted with a fitting hole that is formed to have a non-circular cross section. A liquid gear pump in which the rotational driving force receiving portion that receives the rotational driving force of the drive shaft has a convex curved shape so as to prevent local engagement due to relative displacement in the circumferential direction.
