によりノ々ルブステムを軸芯方向に押圧している。In general, in a valve train in which a camshaft drives a plurality of knob stems arranged radially in a combustion chamber, the suppression direction of the rocker arm and the iib core direction of the knob stem coincide with each other. A twin blocker arm is interposed between the rocker arm and the knob stem, thereby pressing the knob stem in the axial direction.

。The purpose of Kokusei BA is to obtain a device in which the blocker arm is always suppressed by the axial force of the nonoru stem no matter which direction the rocker arm pushes the blocker arm. In a valve operating system for an internal combustion engine in which a camshaft is linked to a camshaft through a rocker arm and a camshaft through a rocker arm and a camshaft, the shaft of the blocker arm is connected to the camshaft through a rocker arm and a camshaft. It is characterized in that it is disposed parallel to a perpendicular plane and perpendicular to the nodal stem in the swing range of the blocker arm.

ルブの耐久性が向上する効果を有する、In this way, according to the present invention, the blocker arm shaft θυ is aligned parallel to the plane perpendicular to the blocker arm (4m) (5a) and within the swing range of the blocker arm 0Q. Since they are arranged orthogonally to each other, no matter which direction the rocker arm (8) presses the sub-rocker arm (11), the sub-rocker arm (QI) always presses against the knob stem (4a) of each valve (4) (5). ) (5a) is pressed in the axial direction, which has the effect of improving the durability of the knob.
