Abstract
A pump for supplying high-pressure includes a plunger, a cylinder, a body, and a holder. The uppermost end surface of the cylinder is an end of the cylinder that is closest to the pressurizing chamber. A first gap formed between the outer periphery of the cylinder and the body in the radial direction is smaller than a second gap formed in the radial direction between the inner diameter of the pressurizing chamber and the outer diameter of the plunger. A radial gap is formed in an entire area of the cylinder in an axial direction thereof.
