球面ラジアス中心位置を設定した ＤＯＨＣエンジンの動弁装置。[Scope of Claim for Utility Model Registration] A pivot serving as a swinging fulcrum of the rocker arm is arranged between a cam that comes into contact with the rear side of the rocker arm and a plug hole formed in the center of the cylinder bore when viewed from the cam axis direction. In addition, a DOHC having a large spherical radius on the rocker arm side at the contact portion between the rocker arm and the pivot.
In a valve train for an engine, when viewed from the camshaft direction, the perpendicular line of the contact circle where the rocker arm and the pivot contact each other at the contact portion is inclined toward the cam with respect to the pivot axis in the valve closed state. A valve train for a DOHC engine that sets the center position of the spherical radius of the Rotsuka arm.
