<p>[Problem] To provide a valve lifter that can reduce the friction between the edge on the top and bottom ends of a valve lifter and a cylinder head bore. [Solution] This valve lifter (100) has a crown section (110) on which a cam slides, and a skirt section (120) that extends down from the crown section. A first texture groove (132) for retaining lubricating oil is formed in the circumferential direction in a top end region (130) on the skirt section (120), and a second texture groove (152) for retaining the lubricating oil is formed in the circumferential direction in the bottom end region (150) separated by an intermediate region (140) adjacent to the top end region (130).</p> |
