摘要: In a lift amount adjusting device in a valve-operating mechanism which changes at least a lift amount, a rocker arm is rockably arranged in a driving-force transmitting path for transmitting a driving force of a valve cam to an engine valve, and a jig abuts on the rocker arm to establish a rocking fulcrum in place of a hydraulic tappet which generates an urging force for adjusting a clearance of the driving-force transmission path. Even when an engine is stopped to make the hydraulic tappet inoperative, the jig secures a rocking fulcrum of the rocker arm, thereby enabling adjustment of the lift amount of the intake valve. Also, a load acting on the rocker arm during the adjustment of a lift amount of the intake valve is supported by the jig, and is not transmitted to the hydraulic tappet.
