    • A valve train for an internal combustion engine includes a rocker shaft (9) provided with an oil passage, first and second rocker arms (7, 8) having support parts (7a, 8a) provided with bores (7b, 8b) to receive the rocker shaft (9) therein so as to be supported on the rocker shaft (9) for rocking motion, and a rocker arm interlocking mechanism (10) for selectively engaging or disengaging the first and the second rocker arms (7, 8). The first rocker arm (7) is provided with a pressure chamber (33) holding a piston (30) therein, a straight connecting passage 34 connected to the pressure chamber (33) and an oil passage (35)formed in the rocker shaft (9). An open end surface (7b1) of the bore (7b) of a first support wall (7e) of the rocker arm (7) is on an axially outer side of the pressure chamber (33). The straight connecting passage (34) is inclined to the axis of the bore (7b) so that an imaginary passage (39) on an extension of the connecting passage (34) extended toward the open end surface (7b1) intersects the open end surface (7b1). The outermost side surface (7e1) of the first support wall (7e) has an inclined section inclined to the axis of the bore (7b) along the connecting passage (34).

    • There is provided a construction for a cam rotation sensor attaching portion where a cam rotation sensor is attached which detect the rotation angles of camshafts (1, 3) supported on cam holders (lower cam holder 12, upper cam holder 13), the construction being characterized in that portions to be detected (projections 18) are provided on thrust plates (17) fixed to axial ends of the camshafts so as to be brought into abutment with an axial end face (a thrust receiving face 31) of the cam holder for regulating axial positions of the camshafts, and that a sensor (a proximity sensor 23) for detecting the passage of the portions to be detected from an axial direction of the camshafts is attached to a member (a sensor attaching wall 20) which is integrated into the cam holder. According to this construction, since the relative positioning accuracy between the portions to be detected and the sensor attaching portion with respect to the axial direction of the camshafts can easily be improved, a high detection accuracy can be obtained. Moreover, since the sensor and the head cover can be attached to and detached from the cylinder head without affecting each other, the maintenance and servicing properties thereof can be enhanced.
    • 提供一种用于凸轮旋转传感器安装部分的结构,其中安装有凸轮旋转传感器,其检测支撑在凸轮保持器(下凸轮保持器12,上凸轮保持器13)上的凸轮轴(1,3)的旋转角度,该结构为 其特征在于,被检测部分(突起18)设置在固定在凸轮轴的轴向端部的止推板(17)上,以与凸轮轴的轴向端面(推力接收面31)邻接 调节凸轮轴的轴向位置,并且用于检测从凸轮轴的轴向方向通过待检测部分的传感器(接近传感器23)附接到一体成型(传感器安装壁20) 凸轮架。 根据该结构,能够容易地提高检测部与传感器安装部之间相对于凸轮轴的轴向的相对定位精度,能够获得高的检测精度。 此外,由于传感器和头盖可以与气缸盖相连接和拆卸而不会相互影响,所以可以提高其维护和维修性能。
