Abstract
In a tappet for use in an internal combustion engine, a tip is fitted in an engage bore between the top wall of the tappet and an engine valve shaft. The tip has a chamfered portion over which a circumferential projection is pressed by a punch so as to fix the tip in the engage bore firmly. A caulking groove is formed by the punch around the engage bore on the top wall. Owing to the chamfered portion of the tip, a cracking is prevented at the bottom of the groove.
