Abstract

PURPOSE:To form the titled sealing part with high reliability and high yield, in a short time and economically, by supporting a valve stem material and a sealing part forming sleeve with higher hardness concentrically, rotating the latter and pressing the former against the latter at the same time to insert the sleeve end into the valve stem material in a fixed amount, and removing any other part except the inserted part.
