PURPOSE: A device for inspecting a dual gearing type gear is provided to detect transmission errors by directly measuring the angular displacement of a gear so that a noise quality inspection is possible at a low rotary speed or load. CONSTITUTION: A device for inspecting a dual gearing type gear comprises master gears(10,15), a master gear mounting part, a test gear(40), a test gear mounting part, a driving unit, and a transverse direction displacement detecting units(60,65). The master gear becomes a reference for inspecting a gear processing state. The master gear mounting part mounts the master gear. The test gear rotates by gearing the master gear. The test gear mounting part mounts or separates the tester gear. The driving member applies torque with respect to one of master gears. The transverse direction displacement detecting units detect the displacement in a direction perpendicular to shafts(22,32) where the master gears are mounted.
