摘要：PROBLEM TO BE SOLVED: To improve the workability at the time of brazing ceramic chips, and to improve the connecting strength by reducing the dimension of a blow hole, and to prevent the generation of break of the ceramic chip so as to improve the reliability at the time of using a tappet. SOLUTION: A ceramic chip 22, which contacts with a cam, is brazed to a bottom surface so as to cover a bottom surface 21b of a tappet main body 21a. Chamfering C is performed to a peripheral edge of the bottom surface over the whole thereof. A radial pattern can be formed from the center of the bottom surface of the tappet main body to the peripheral edge, and the surface roughness of the bottom surface due to the pattern is desirably restricted at 2-15μm. Rounding R is desirably performed to the whole of the peripheral edge of a surface, which contacts with the cam of the ceramic chip.
