Abstract
A rocker arm unit which constitutes a valve gear of an internal combustion engine, includes a lash adjuster including a cylindrical body and a plunger formed into a cylindrical shape and accommodated in the body, a rocker arm extending in a direction perpendicular to a vertical direction, and a clip configured to be fixed to an upper end of the body and formed with a retainer having a retaining portion which is configured to be swaged onto an inner circumferential surface of the upper end of the body. The clip has an extension extending integrally from the retainer. The extension has an upper end engaged with the rocker arm to prevent the rocker arm from falling off the lash adjuster. The retaining portion is configured to abut against the stepped portion of the plunger from above to prevent the plunger from coming off upwardly out of the body.
