Abstract

In a lubricating device of an internal combustion engine having a crank chamber and a transmission chamber, which is arranged in the rear of the crank chamber so as to accommodate therein a gear transmission provided with a main shaft and a pump shaft. The pump shaft is shared by a scavenging pump and a feed pump for feeding oil to a part to be lubricated and to which motive power from the crank shaft is transmittable. An axis of the pump shaft is arranged below an axis of the main shaft. A pump gear located on the pump shaft meshes directly with a primary driven gear, which meshes with a primary drive gear located on the crank shaft so as to form a primary gear reduction mechanism in cooperation with the primary drive gear.
