Abstract

　下端が閉塞する筒状ボディ（２１）の内周に鋸歯状の雌ねじ（２４）を形成し、その雌ねじ（２４）にアジャストスクリュ（２５）の外周に形成された鋸歯状の雄ねじ（２６）をねじ係合する。ボディ（２１）の内部にリターンスプリング（２７）を組込んでアジャストスクリュ（２５）を突出する方向に向けて付勢する。アジャストスクリュ（２５）の下面とボディ（２１）の底面間に摩擦部材（３１）を組込む。アジャストスクリュ（２５）の上部に形成された球面状のピボット部（３２）を設け、そのピボット部（３２）の上端に係合孔（３３）を形成し、その係合孔（３３）に係合した回転操作工具Ｔの回転操作によりアジャストスクリュ（２５）を締付け方向に回転し、アジャストスクリュ（２５）の下面を摩擦部材（３１）に圧接させて、アジャストスクリュ（２５）を押し込み状態に保持し、スイングアーム式動弁装置に対するラッシュアジャスタの組込みの容易化を図る。
