<p>A MOTOR WITH A GEAR REDUCER (5) COMPRISES AN ELECTRIC MOTOR (4) FOR GENERATING A ROTATING OUTPUT.THE GEAR REDUCER (5) HAS A PLURALITY OF GEARS INCLUDING A FINAL STAGE GEAR AND HAS AN AXIAL THROUGH HOLE (66) FORMED THEREIN IN COAXIAL RELATION TO AN AXIS OF ROTATION OF THE FINAL STAGE GEAR. THE ELECTRIC MOTOR (4) INCLUDES A HOUSING (6) HAVING OPPOSITE END PORTIONS, A STATOR SECURED TO THE HOUSING (6) AND HAVING AN INNER PERIPHERY DEFINING A CENTRAL SPACE THEREIN, A ROTOR ROTATABLY FITTED IN THE CENTRAL SPACE OF THE STATOR, FOR GENERATING THE ROTATING OUTPUT DURING ROTATION THEREOF. AN OUTPUT SHAFT (9) CONNECTED THROUGH THE GEAR REDUCER TO THE ROTOR (8) IS ROTATIVELY DRIVEN THEREBY, FOR OUTPUTTING THE ROTATING OUTPUT FROM THE ROTOR THROUGH THE GEAR REDUCER. THE ROTOR (8) HAS AN AXIAL THROUGH HOLE FORMED THEREIN IN COAXIAL RELATION TO AN AXIS OF ROTATION OF THE ROTOR. THE OUTPUT SHAFT (9) EXTENDS THROUGH THE AXIAL THROUGH HOLE (8A) OF THE FINAL STAGE GEAR (5D) OF THE GEAR REDUCER (5) AND THE AXIAL THROUGH HOLE OF SAID ROTOR, AND IS ROTATABLY SUPPORTED BY THE OPPOSITE END PORTIONS OF THE HOUSING.THE INNER CASING (6B) IS FIXED TO A VEHICLE BODY.</p> |
