<p><P>PROBLEM TO BE SOLVED: To provide a sliding lifter and its manufacturing method, easy in manufacture, by easily improving processing accuracy in an outer peripheral surface, even when having a rotation preventive projection. <P>SOLUTION: This sliding lifter 1 has a cross-sectional annular ring shape, and slides its outer peripheral surface 110 to a sliding port 31A arranged in an engine. The sliding lifter 1 is formed by orthogonally supporting a freely rotatable roller 2 in the axial direction between mutual support parts 12 formed in a pair in mutually opposed positions in one end part 101 in its axial direction. The rotation preventive projection 13 for preventing rotation of the sliding lifter 1 by engine with a rotation preventive groove 32 formed in the axial direction of the sliding port 31A, is formed in a part in the peripheral direction unformed with a pair of support parts 12 in the one end part 101 in the axial direction of the sliding lifter 1. The rotation preventive projection 13 is composed of a projection part 131 projecting outside the one end part 101 in the axial direction, and an engaging end part 132 projecting outside in the radial direction by bending to the projection part 131. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
