PROBLEM TO BE SOLVED: To provide high intake/exhaust performance by protruding both the right and left end sections of the motor shaft of a DC brushless motor from a motor casing, and assembling pump bodies to both the right and left end sections. SOLUTION: Both the right and left end sides of a motor shaft 4 are protruded from a motor casing 1 as output shafts respectively. Pump bodies B1, B2 having two heads are assembled to both the right and left end sections 4a, 4b of the motor shaft 4 protruded from the motor casing 1 of a DC brushless motor as output shafts. Each of the pump bodies B1, B2 is constituted of a diaphragm 12 and a valve seat 14 having a valve 13. When the DC brushless motor is driven, the diaphragm 12 is operated via a connecting rod 17 by the rotation of an eccentric shaft 4 fitted to the motor shaft 4, and air can be fed to a required place through the valve 13, an intake/exhaust passage, a connecting port 22 and an intake/exhaust hose, for example. |
