PROBLEM TO BE SOLVED: To miniaturize an electric motor unit. SOLUTION: In the electric motor unit, provided with a motor 11 with a warm-gear speed reducing device, a controller board 40, and a sensor board 50, a lead 50 of the sensor board 50 is inserted into a through-hole 46 of the controller board 40 and soldered. An assembled unit of these controller board 40 and sensor board 50 are stored in a storage chamber 25 of a board storing part 24 formed on a gear frame 20. A sensor 52 on the sensor boar 50 faces a magnet ring 16 which comes into a state capable of detecting revolutions. The controller board 40 is put in a state with the storage chamber 25 being used three-dimensionally effectively. Because the controller and sensor boards use the storage chamber three-dimensionally, a plane area of the storage chamber, of the entire plane area of the electric motor unit can be reduced. |
