PURPOSE: A precise planet gear reduction device is provided to improve a process, an assembly, and the precision of a reducer by assembling configuration members on an attachment side of a main frame and a rear cover. CONSTITUTION: A main frame includes a bearing combination unit and a first oil seal combination unit(35). The first oil seal combination unit includes a bearing combination unit and a first hitching protrusion. An output shaft is combined with the main frame and the oil seal for an output shaft is combined with the first oil seal combination unit. A planet gear carrier combined with planet gears(61) is installed on the rear of the output shaft. The rear of the planet gear carrier is supported by the bearing for a carrier. An outer bearing combination unit, an inner bearing combination unit, a second oil seal combination unit, and a second hitching protrusion are formed on the rear cover. A sun gear(71) is engaged with the planet gears combined with the planet gear carrier.
