Abstract: A lubricant structure of an engine capable of easily and compactly attaching and detaching primary oil filters connected to oil intake sides of two oil pumps to and from a crank case. A power transmission chamber in the crank case dually divided in a crankshaft direction is an oil reserving portion. The lubricant structure includes a first oil pump for pressure-feeding oil of the oil reserving portion to a lubricant point, a second oil pump for returning the oil returned to the crank chamber to the oil reserving portion, and first and second oil filters connected to the oil intake sides of the oil pumps. The first oil filter is inserted from one of left and right crank case members, the second oil filter is inserted from the other crank case member, and both the oil filters are closed by oil filter caps.
