Zusammenfassung: | An engine having a variable valve mechanism arranged to switch a lift degree of a valve between a low speed state and a high speed state includes a cam carrier defined by a cam bearing portion, a rocker shaft support, and a hydraulic cylinder support. The cam bearing portion is provided on a line passing through the bore center of a cylinder in a plane perpendicular or substantially perpendicular to the camshaft. The low speed rocker arm swings in response to the low speed cam of the camshaft. The high speed rocker arm swings in response to the high speed cam of the camshaft. The low speed rocker arm includes a through hole. A connecting pin is slidably inserted into the through hole and urged toward the hydraulic cylinder support. A hydraulic cylinder is provided in the hydraulic cylinder support. |
