(54) Fluid pump and high-pressure fuel feed pump


(57) The invention relates to a fluid pump, wherein a cylinder 20 supporting a plunger 2 and a pump housing 1 are formed with dissimilar metals and a pressing mechanism to press the cylinder 20 and the pump housing 1 relatively to each other is provided so that a pressurizing chamber 12 is sealed through a pressing surface between the pump housing 1 and the cylinder 20, whereby the number of seal points can be reduced and a reduction in reliability can be eliminated while realizing a reduction in weight of the pump housing 1 and a reduction in cost due to increase in cutting capability using a soft member such as aluminium alloy for the pump housing 1.
