ター。 In an engine valve lifter comprising a light metal cylindrical member and a disc-shaped wear-resistant member provided at the upper end of the cylindrical member, the upper surface of which serves as a cam sliding surface,
An annular notch step is formed on the outer periphery of the upper end of the cylindrical member, and an annular flange that hangs downward and can be fitted into the notch step is formed on the lower periphery of the wear-resistant member. At the same time, a ring-shaped groove is formed on the inner circumferential surface of the flange portion, and the vertical wall surface of the notch step portion of the cylindrical member plastically flows into the ring-shaped groove, thereby connecting the cylindrical member and the wear-resistant member. An engine valve lifter characterized by being combined with.
