A valve train device for an engine adapted to swing a rocker arm 11 swingably supported on a rocker shaft 14 to drive a valve which opens and closes a valve opening formed in a combustion chamber, the device comprising: a swing member 9 swingably disposed and driven to swing by driving means; a intermediate rocker member 10 provided between a swing cam surface 9b formed on the swing member 9 and a pressurized rocker face 11b formed on the rocker arm 11, for transmitting the movement of the swing cam surface 9b to the pressurized rocker face 11b; and a intermediate rocker moving mechanism for causing the rocker shaft 14 to rotate to move contact points of the intermediate rocker member 10 with the swing cam surface 9b and the pressurized rocker face 11b, whereby valve opening duration and the amount of valve lift can be continuously controlled. <IMAGE>
