A miniature pump equipped with: a pump chamber communicated with a suction port by way of a check valve and communicated with a discharge port by way of another check valve; a driving portion for performing a pump function by increasing and decreasing a volume of the pump chamber; a driving plate attached to the driving portion for reciprocating the driving portion; a rotating plate fixed to an output shaft of a motor; a ball disposed at a location which is between the driving member and the rotating plate, and apart from the output shaft; and means for applying a force to a surface of the driving plate on a side of the rotating plate for bringing the driving plate into close contact with the ball, in which an inclined direction of the driving plate is continuously changed by a movement caused due to rotations and revolutions of the ball as the rotating plate rotates, thereby reciprocating the driving portion and performing a pump function. <IMAGE> |
