PROBLEM TO BE SOLVED: To suppress the size enlargement of a driving motor as a whole by effectively using both sides of a motor shaft as output shafts by protruding both end sections of the motor shaft from a motor casing as the output shafts. SOLUTION: The motor casing 1 of a DC brushless motor is constituted of a cup-like casing 1a and a cap-like casing 1b, and a rotor 2, a stator 3, and a motor shaft 4 linked with the rotor 2 are incorporated in the casing 1. At the same time, a motor driving circuit board 5 mounted with electronic parts 5a which control the drive of the motor is provided in the casing 1. In addition, pumps A and B each of which is provided with two head sections 15 and two joint ports 22 for suction and exhaust hoses on the top and bottom sides are respectively assembled with both right and left end sections 4a and 4b of the motor shaft 4 protruded from the casing 1 as output shafts. Thus, the driving motor of the diaphragm type pumps A and B which is provided with a total of four head sections 15 is constituted. |
