PURPOSE: To prevent vibration of a motor, and also, to position the motor against a battery by fitting one opening end of a cylindrical part provided on a connecting base to a bearing part protruded to the rear part of the motor and holding the rear part of the motor.
CONSTITUTION: A connecting base 30 is provided with a roughly circular bottom plate 32 in which a hole 31 is opened in the center part, a cylindrical part 33 extended from the hole 31, and inserting/holding pieces 34, 35 which extend from the peripheral end of the bottom plate 32 and insert and hold the rear part of a flat part 26b of a motor 26. The cylindrical part 33 is fitted to a bearing part 26a protruded to the rear end part of the motor 26 and holds the rear part of the motor 26. In such a way, the connecting base 30 absorbs vibration generated at the time of operation of the motor, and reduces vibration of a main body case 20 at the time of operation of the motor 26. Also, by fitting to the bearing part 26a of the cylindrical part 33, positioning of a battery 50 to the motor 26 is executed. An A part of the inserting/ holding pieces 34, 35 of the connecting base 30 and a B part fitted into a containing case 40 insert and hold the flat part 26b of the motor 26, and also, go into a clearance formed between the flat part 26b and the main body case 20 and reinforce the case 20.
