PROBLEM TO BE SOLVED: To provide a decompressor mechanism of an engine having a simple structure with the small number of components, and reducing the cost. SOLUTION: A bearing hole 22 turnably supporting a decompressor camshaft 23, is formed on a driven timing gear 26b integrated with a variable valve cam shaft 15, a decompressor cam 24 is connected to one end part of the decompressor camshaft 23, an arm 25 is connected to the other end part, further a connecting part 26 bent from the arm and engaged with a connection groove 3 of a centrifugal weight 30 is connected on a tip of the arm 25, and an enlarged part 27 is connected to a tip of the connecting part 26. The enlarged part 27 is axially held between the driven timing gear 16b and the centrifugal weight 30. COPYRIGHT: (C)2004,JPO
