Claims

[Claims for Utility Model Registration] 1. A pump case in which a rotor is housed is divided into two parts on a plane substantially perpendicular to the rotational axis of the rotor and joined together, and a recess is formed in at least one of the divided joined faces. A lubricating oil pump characterized in that the recessed portion constitutes an outlet and an inlet passage for lubricating oil. 2. A lubricating oil pump attached to a cylinder block of an internal combustion engine, which is provided with a joint that spans the outlet of the outlet passage and the inlet of the gear case and directly connects the inlet and the outlet, as described in claim 1. lube oil pump.
