Abstract

PURPOSE:To adjust a valve clearance at one position of a lifter by arranging an equalizer between a lifter driven by a cam and the valve rod tips of multiple intake valves, driving the equalizer at the position of the center of gravity of the valve rod tip, and forming each contact point into a spherical surface. CONSTITUTION:There intake valves 7 are provided per cylinder and are driven by a cam 15a. An equalizer 12 is arranged between a lifter 13 driven by the cam 15a and the valve rods 7a of the intake valves 7, and the lifter 13 drives the equalizer 12 at the position of the center of gravity among tip positions of three valve rods 7a. The contact point of the lifter 13 and the equalizer 12 and the contact point of the equalizer 12 and the valve rod tip 17 are spherical surfaces 18, 19. Accordingly, the clearance of the valve can be adjusted with a shim 14 at one position.
