ABSTRACT:
A variable valve device for an internal combustion engine includes an internal combustion engine body having a plurality of cylinders, a variable valve mechanism which is provided in the body and is switchable between at least two modes with oil pressure, a mode switching oil control valve which switches the variable valve mechanism to each mode, and a camshaft-driven mode switching oil pump which supplies an oil pressure for switching driving to the variable valve mechanism according to the switching of the mode switching oil control valve. The mode switching oil control valve is, along with the mode switching oil pump, provided in an outer wall surface of the body.
