Abstract: In a conventional high-pressure fuel pump, the interference fit part between a plunger and a retainer comes loose with time due to environmental factors and this reduces the clearance between the retainer and a tappet more than necessity, resulting in increase in the contact face pressure between the plunger and a cylinder when a side force acts on the plunger, which causes seizure between the plunger and the cylinder. In this invention, a protrusion protruding toward the tappet is provided around the through-hole for press-fitting the plunger, the through-hole provided in the center portion of the retainer. Since the clearance between the retainer and the tappet can sufficiently be kept even if the joint between the retainer and the plunger comes loose, the seizure between the plunger and the cylinder and the breakage of the plunger are less likely to occur even if the side force acts on the retainer.

Abstract: The challenge of the present invention is to prevent a crook line part of a dotted line from being displayed in half tone. The present invention is contrived to calculate a center coordinate of a texture pixel in a zone including a reference texture beginning point coordinate S_Begin as reference texture corrected beginning point coordinate S_Begin?. It is followed by calculating a center coordinate of a texture pixel in a zone including a reference texture end coordinate S_End as reference texture corrected end coordinate S_End?. A crook line part of a dotted line is drawn by fixing a reference coordinate to the S_Begin? or S_End? if a pixel to be drawn exists within a fixing section.
