    摘要: A valve operating system in an internal combustion engine includes a cam shaft provided with a valve operating cam, a rocker arm having a pair of support wall portions which are integrally connected at their base ends to a swinging support portion swingably supported on a support member mounted on a cylinder head and which are opposed to each other at a distance in a direction along the swinging axis of the swinging support portion, a support shaft supported between the support wall portions, and a roller which is rotatably supported on the support shaft with a bearing interposed therebetween so as to be in rolling contact with the valve operating cam. A lower connecting wall interconnecting lower portions of the base ends of the support wall portions is projectingly provided on the swinging support portion in a manner opposed to an outer peripheral surface of a lower portion of the roller. Thus, it is possible to increase the rigidity of the rocker arm, while avoiding an increase in size of the rocker arm.

    摘要: A first thrust limiting member and a second thrust limiting member are provided on a cam shaft rotatably carried between a lower cam shaft holder and an upper cam shaft holder which are fixed to an upper surface of a cylinder head 1, so that the first and second thrust limiting members and abut against the cam shaft holders 9 5 and 10 5 . The second thrust limiting member has a plurality of detected projections provided around of an outer periphery thereof, so that the detected projections are detected by a TDC sensor 37 mounted to a head cover of the engine. Thus, the rotated position (phase), the angle of rotation and the number of rotations of an rotary shaft of an engine such as a cam shaft 6e and a crankshaft can be detected with good accuracy in a structure including a decreased number of parts, and the axial dimension of the rotary shaft of the engine can be reduced.

    摘要: A valve operating system in an internal combustion engine includes a cam shaft provided with a valve operating cam, a rocker arm having first and second support walls opposed to each other at a distance, a support shaft mounted to extend between the support walls, a roller rollably supported on the support shaft through a bearing, and an urging means for urging the rocker arm in a direction to bring the roller into rolling contact with the valve operating cam. In the valve operating system, one of the support walls included in the rocker arm is integrally provided with a receiving portion which contacts with the urging means. Thus, the structure of the rocker arm can be simplified in such a manner that the receiving portion is positioned to the side of the roller; and an increase in size of the rocker arm can be avoided and further, the inertial weight is reduced. Therefore, it is possible to conveniently accommodate the high-speed rotation of the internal combustion engine.

    摘要: A lost motion mechanism (36) that biases a free rocker arm (33) of a lift-amount changing member capable of lifting a valve in a direction to abut against a cam includes a spring (45) accommodated in a support portion (24e). The support portion is a recessed portion integrally formed on a camshaft holder below the free rocker arm. The vertical dimension of an engine is reduced as compared with a case where the support portion is provided above the free rocker arm. A camshaft cap supports the camshaft and a bolt that fastens the camshaft cap to the camshaft holder are not required.
