Abstract: A large-diameter-side end surface (104a) of a cotter (104) can be supported by a cotter holder (32) from below through inserting a shaft member (102) along an inner periphery of the cotter (104) from above the cotter (104). In this state, a protrusion (104b) of the cotter (104) and an annular groove (102a) of the shaft member (102) are fitted to each other, and the cotter (104) and a retainer (103) are taper-fitted to each other. Consequently, the cotter is prevented from being unstable, and hence it is possible to assemble the retainer (103) and the cotter (104) to the shaft member (102) with good accuracy.

Abstract: 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.
