top wall 1a of the body 1 a cam receiving plate 2 having the same diameter with an outer diameter of the body 1 is brazed by brazing filler material 4 which may be preferably sn zn alloy having melting point of 200 u00b0 to 380 u00b0 c such as sal apx sal crz and sal apy according to jis maximum use temperature of the tappet is usually about 150 u00b0 c and to obtain required joining strength under use temperature condition melting point needs more than 200 u00b0 c furthermore when the body 1 is heated in soldering strength decreases as it comes to heat treatment temperature such as 500 u00b0 c at 380 u00b0 c strength is suddenly decreased accordingly it is necessary not to heat the body to over 380 u00b0 c by the brazing filler material 4 having melting point less than 380 u00b0 c to braze the cam receiving plate 2 the powdery or sheet like brazing filler material is put on the top wall 1a and the cam receiving plate 2 is disposed thereon then the body 1 and the cam receiving plate 2 are heated at roughly equal temperature to melting point of the brazing filler material 4 in a suitable heat source such as a vacuum furnace so that the brazing filler material 4 is melted thereby joining the top wall 1a integrally with the cam receiving plate 2 surface treatment such as cu metal plating on the joining surface of the cam receiving plate 2 increases joining property of the brazing filler material 4 to provide stable qualities in a groove 5 in the middle of the lower surface of the top wall 1a a tip 7 made of wear resistant metal and engaged with.
