Description
前記中間製品の一端側における両側壁を内側に傾斜させるように折り曲げる側壁曲げ工程と、
傾斜した両側壁の外面に対し上方から下方に向けてしごき成形用型を押し込んで、前記両側壁の外面部をしごき成形することにより、両側壁の構成材を下方に塑性流動させて、前記一端側連結壁の両側に下方突出状にバルブステムガイド壁を形成するしごき工程と、を含むことを特徴とするロッカーアームの製造方法。
発明[2]のロッカーアームの製造方法によれば、両側壁の基端側内面に肉盛部が形成されるため、両側壁が強固に固定されて十分な強度を有するロッカーアームを確実に製造することができる。

20…両側壁
30…一端側連結壁
31a…しごき成形されない部分
35…バルブステムガイド壁
51…上型
52…下型
60…しごき成形用型
