Abstract
PURPOSE:To smoothly engage and disengage rocker arms for low speed and rocker arms for high speed by pivoting the rocker arms for high speed to rocker shaft parts formed integrally with the rocker arms for low speed. CONSTITUTION:Swing arm type rocker arms 11a, 11b for low speed pivoted to end pivots 9a, 9b are formed integrally with rocker shaft parts 18a, 18b. Rocker arms 15a, 15b for high speed are pivoted to the rocker shaft parts 18a, 18b adjacent to the rocker arms 11a, 11b for low speed. The rocker arms for low speed and the rocker arms for high speed are engaged and disengaged by pressurized oil from pressure-oil chambers 21a, 21b. The defective engagement of both the rocker arms can be thus reduced, and both the rocker arms can be smoothly engaged and disengaged.
