摘要： A cam lobe 22 is formed as a single part, not formed together with a shaft body 21. The shaft body 21 penetrates through bearing holes 13F, 13M, and 13R, as well as a mounting hole 24 provided in the cam lobe 22, which is arranged in between the adjacent bearing holes 13F, 13M, and 13R. The bearing holes 13F, 13M, and 13R each in a perfect circular shape can be achieved, since there is no need to divide the bearing holes 13F, 13M, and 13R into two semi-circular arc shaped concave portions. Consequently, a camshaft 20 can be supported so as to rotate smoothly.

摘要： In a process of mounting a camshaft 20 to a supporting member 10, a shaft body 21 is firstly inserted into a first bearing hole 13F in the front side of the supporting member 10, before the shaft body 21 is axially moved toward the second bearing hole 13R. In order to get a cam lobe 22 through a concave bearing portion 13M in a semicircular arc shape, rotation of the camshaft 20 enables a cam nose 22b to be directed downward, which is opposite from the concave bearing portion 13M. This enables avoiding the interference between the cam nose 22b and the concave bearing portion 13M, even when the curvature radius of the concave bearing portion 13M is reduced. Consequently, reduction of the curvature radius of the concave bearing portion 13M achieves the downsizing of the supporting member 10.
摘要翻译： 在将凸轮轴20安装在支撑部件10上的过程中，在轴体21朝向第二轴承孔轴向移动之前，首先将轴体21插入支撑部件10的前侧的第一轴承孔13F 13R。 为了通过半圆弧形状的凹入轴承部分13M获得凸轮凸角22，凸轮轴20的旋转使得凸轮端头22b能够向下指向与凹入轴承部分13M相反的向下。 这样，即使凹入轴承部13M的曲率半径减小，也能够避免凸轮凸起22b与凹入轴承部13M之间的干涉。 因此，凹入轴承部13M的曲率半径的减小实现了支撑部件10的小型化。

摘要： A rocker arm includes a roller rotatably mounted between two sidewalls thereof. The roller is pressed by a cam. The rocker arm also includes two washers that reduce a wobbling motion of the roller with respect to the cam. The washers guiding mechanism the rocking movement of the rocker arm in the up-and-down direction, thereby reducing wobbling motion of the rocker arm when an engine runs.
