    摘要： A rocker arm (63) has a valve connection section (63a) to which tappet screws (70) individually in contact with a pair of engine valves are screwed such that the positions of the tappet screws in an advance/retreat direction are adjustable. The rocker arm (63) further has a cam contact section (65) in contact with a valve operating cam (69), and the rocker arm (63) is interlinked and connected to the engine valves. One end section of a first link arm (61) pivotally supported at the position where an engine body is fixed and one end section of a second link arm (62) pivotally supported by a movable shaft (68a) capable of being displaced are pivotally connected to the rocker arm (63). The rocker arm (63) is formed such that the width of the valve connection section (63a), which width is in the direction of the rotation axis of the valve operating cam (69), is greater than the width of other portions. This structure enables the amount of lift of the engine valves to be continuously varied, and makes a valve operating device more compact while achieving excellent following ability of the engine valves in opening and closing operation.

    摘要： A needle roller bearing has an outer ring having two outer ring members (12) split by a split line extending in the direction of the axis of the bearing, and also has needle rollers rollably placed on the raceway surface of the outer ring. The needle roller bearing satisfies the relationship of L/w

    摘要： A valve system of an engine, wherein a rocker arm swung according to the movement of a valve cam is brought into contact with an engine valve through a hydraulic tappet. A receiving member (41) receiving the hydraulic tappet (12) is slidably fitted to the rocker arm (13) to which the hydraulic tappet (12) is fitted, a restriction part (29) facing the receiving member (41) is formed on the opposite side of the hydraulic tappet (12), and an adjust screw (44) for adjusting a clearance between the restriction part (29) and the receiving member (41) when the engine valve is closed is threaded to an engine body (5) so that the forward/backward movement position thereof can be adjusted to bring it into contact with the receiving member (41) when the engine valve is closed. Thus, the lift of the engine valve can be easily and accurately adjusted while eliminating complicated machining and production control to openably drive the engine valve by the rocker arm through the hydraulic tappet.
