摘要： There is provided a fuel pump disposed outside of a fuel tank, in which the durability of a bearing is enhanced. A fuel pump (20) includes: a drive shaft (40); a rotary swash plate (50) fixed to the drive shaft (40); a cylinder (241); and a piston (25) provided in such a manner as to be biased such that one end thereof abuts against the rotary swash plate (50) and be movable inside of the cylinder (241) according to the rotation of the rotary swash plate (50). The rotary swash plate (50) includes an annular rotary plate (52) that abuts against the piston (25) and a bearing (51) having a drive side first race (511) fixed to the drive shaft (40), a driven side second race (512) fixed to the annular rotary plate (52), and a plurality of rolling elements (513) interposed between the first race (511) and the second race (512). The bearing (51) has an inclination axis (514) inclined with respect to the axis (43) of the drive shaft (40). A straight line (515) connecting contact points (511c) and (512a) between the rolling element (513) and the races (511) and (512) is not perpendicular to the inclination axis (514).
