Abstract

PURPOSE:To shorten the axial length of rocker shafts by arranging plural switching mechanisms for changing plural rocker arms from an interlocking condition to a non-interlocking condition so that these switching mechanism overlap each other in the direction of shaft line of the rocker shaft. CONSTITUTION:Rocker shafts 3, 4 are fixed, by bolts, on a cam cap 1 pivoting a cam shaft 2. A low-speed air intake cam 6, a high-speed air inlet cam 7, an exhaust cam 8, and a low-speed air intake cam 9 are respectively formed integrally with the cam shaft 2. In this case, a first rocker arm 12 equipped with a roller 11 which contacts the low-speed air inlet cam 6, a second rocker arm 14 equipped with a slipper 13 which contacts the high-speed air inlet cam 7, and a third rocker arm 16 equipped with a roller 15 which contacts the low- speed air inlet cam 9 are respectively installed to the inlet side rocker shaft 3. Further, switching mechanisms 31, 32 are respectively installed between the rocker arms 12-16.
