PROBLEM TO BE SOLVED: To provide a dynamic valve mechanism of an engine which can reduce the size of the engine even if a cam housing is arranged in which an internal oil passage 39, and an oil introduction path 38 for supplying oil to the internal oil path 39 by introducing the oil from a cylinder head 4 to the lower-side cam housing are formed.SOLUTION: In an intake side cam sprocket 14 which is arranged adjoining a first lower housing 22, a recess 45 having a depth in a direction separating from the first lower housing 22 is formed at a face opposing the first lower housing 22. Then, an oil introduction path 38 which is formed toward an internal oil passage 39 from a side at which an intake-side variable valve timing device is arranged with respect to the internal oil passage 39 in axial lines L of cam shafts 6, 7 is formed in a region of the recess 45 when viewed from left side in the axial lines L of the cam shafts 6, 7.SELECTED DRAWING: Figure 4 |
