PROBLEM TO BE SOLVED: To improve the production yielding of a small motor by adjusting the output and capacity of the pump chambers thereof. SOLUTION: The pulley (rotating body) 10 of the motor 6 is connected to the lower side of an oscillating body 26 through an eccentric rotating shaft 30. A motor shaft 6a to which the pulley 10 is secured has a spherical lower end part, and vertically movably fitted to the shaft hole part 45 of a motor case 5. The motor shaft 6b is supported by an adjust screw 47 through a synthetic resin washer 49. The adjust screw 47 is screwed to a screw hole 48 communicating with the bottom end of the shaft hole part 45. The height of the motor shaft 6b is changed by the rotating operation of the adjust screw 47, and the compressibility (pump output) of a pump chamber 23 is adjusted. COPYRIGHT: (C)2009,JPO&INPIT
