Abstract

PURPOSE:To prevent breaking away of the driven side rocker arms, by forming oil pressure chambers and fitting holes in driving side and driven side rocker arms, respectively, and slanting an axis of the oil pressure chambers and the fitting holes, from an axis of a rocker shaft. CONSTITUTION:A driving side rocker arm 11 is formed with oil pressure chambers 16. Driven side rocker arms 9, 10 are formed with fitting holes 18 for plungers 17. When the pressure in the oil pressure chambers 16 becomes high, the plungers 17 are pushed out toward the driven side rocker arms 9, 10. An axis of the oil pressure chambers 16 and the fitting holes 18, is slanted at a preset angle from an axis of a rocker shaft 8. While the driving side and driven side rocker arms 11, 9, 10 are connectingly moved with each other, axial component of a force acts on the plungers 17, for pushing back these plungers 17 in the oil pressure chambers 16. In this way, breaking away of the driven side rocker arms can be prevented.
