In an intake/exhaust valve drive device in which both of these pulleys are driven by the same toothed timing belt, both the pulleys of the intake valve driving camshaft and the exhaust valve driving camshaft are attached to the ends of the respective cams. A dowel pin is fixed at the same predetermined angular interval from the cam nose of the cam nose, and the intake valve drive pulley and the exhaust valve drive pulley are formed from a timing pulley that can be shared by them, and the dowel pin is attached to the common timing pulley. A pair of dowel pin fitting grooves are formed that can be engaged with each other, and the pair of dowel pins are arranged in accordance with the pitch of the teeth of the timing belt so that the intake valve camshaft and the exhaust valve camshaft take regular relative angular positions. An intake and exhaust valve drive device for an internal combustion engine that sets the angular interval between large fitting grooves.
