Summary:PROBLEM TO BE SOLVED: To provide a press-fitting device which reduces a press-fit load when press-fitting a valve guide and a valve seat, determines the quality of the press-fitting state, and improves the press-fit position accuracy.SOLUTION: A press-fitting device 1 press-fits a valve seat 92 and a valve guide 91 from the one surface side of a cylinder head 9 and includes: a valve guide holder 51 which holds the valve guide 91; a valve seat holder 52 which holds the valve seat 92 and may move relative to the valve guide holder 51 in a press-fitting direction of the valve guide 91; and a stopper 54 which may restrict the valve seat holder 52 from moving relative to the valve guide holder 51 in the press-fitting direction. 【課題】本発明はバルブガイドおよびバルブシートを圧入する際の圧入荷重を減少し、圧入状態の良否判定を行うことができ、圧入位置精度を向上することができる圧入装置を提供する。【解決手段】バルブシート９２およびバルブガイド９１をシリンダヘッド９の一面側から圧入する圧入装置１であって、バルブガイド９１を保持するバルブガイド保持具５１と、バルブシート９２を保持し、バルブガイド保持具５１に対して相対的にバルブガイド９１の圧入方向へ移動可能であるバルブシート保持具５２と、バルブシート保持具５２のバルブガイド保持具５１に対する前記圧入方向への移動を規制可能なストッパ５４とを備える。【選択図】図２
