), a hydraulic gap adjustment device 15 is interposed between the cam 4 and the rocker arms 3 and 2, and gaps are created between the adjustment screw 5 and the transmission line of the valve shaft heads of the intake and exhaust valves 11' and 10'. Some devices are designed to prevent this at all times and suppress the generation of abnormal noises during operation. (For example, Utility Model No. 54-14011
However, when the above-mentioned hydraulic gap adjustment device 15 is provided, it is necessary to provide a support part for supporting the hydraulic gap adjustment device on the upper side of the camshaft, and an oil supply device to the hydraulic gap adjustment device is required. It is necessary to provide In particular, in a structure with two independent rocker shafts for each intake and exhaust valve, it is necessary to arrange the support part of the hydraulic gap adjustment device and the support part of each rocker shaft in the limited space above the cylinder head. In this case, each of the supporting parts mentioned above tends to interfere with each other, and in order to avoid this interference, the structure becomes complicated and processing becomes difficult. As a result, the uniformity of the oil passage is lost, making it impossible to supply oil evenly. Therefore, there are problems in that it is not easy to incorporate a support with a complicated structure and a hydraulic gap adjustment device into the support in the limited space above the cylinder head.

音は生じない。With the above configuration, since the rocker arm 2.3 is always urged upward by the hydraulic gap adjustment device 15.15, the other end side is urged downward, and the rocker arm 2.3 and the rod 31.32 are Between, rod 31, 32 and intake/exhaust valve 1
This prevents gaps from forming between 1.10 and 1.10. Therefore,
It is possible to prevent abnormal noise from occurring due to contact during operation in the transmission path. Furthermore, as in the conventional example shown in FIGS. 1 and 2, when the intake and exhaust valves 11 (I 1') and lO (10") are operated directly by the rocking of the rocker arm 2.3, the valve A moment acts on the shafts 11a and loa, causing a tilting force to move the valve shafts 11a and loa to the valve guide 12.
.. However, in this device, the rods 31 and 32 are used to move the valve shafts 11a and IOa up and down in the direction of the center line of the valve shafts. Therefore, no force is applied to the valve shafts 11a, 10a, and collision of the valve shafts 11a, 10a with the valve guides 12.12 can be prevented. That is, since the tilting force due to rocking of the rocker arm 2.3 is received by the holder 20 via the rods 31 and 32, no rocker arm type abnormal noise occurs.

Because it is fixed to the cylinder head, it can be easily installed in the limited space above the cylinder head. In addition, the cylinder head with and without hydraulic clearance adjustment device,
It is possible to standardize intake and exhaust valves, valve guides, etc.
