ABSTRACT:
A valve gear for a four-cycle engine having an overhung crankshaft connecting with an output shaft, wherein a guide portion having such a shape folding the output shaft as to return back to a starting point in two turns, is formed on the output shaft, and an interlocking mechanism guided by the guide portion is provided to open the valves for the four-cycle engine. It is preferable that the guide portion is formed as cam face displacing the interlocking mechanism. The guide portion can be formed on a block other than the output shaft for easy machining and also for adjustable valve timing.
