Claims

[Scope of utility model registration request]

A pump device in which a medium is sucked into a pump chamber and discharged from the pump chamber by driving a diaphragm by a rocking motion of a diaphragm driving body accompanying rotational movement of a rotational output shaft of a power source,
The diaphragm is disposed so as to extend in the rotational direction of the rotational output shaft of the power source, and the diaphragm driving body is connected to the rotational output shaft of the power source so as to be inclined through a bearing, and the diaphragm driving body A pump device characterized in that the volume of a pump chamber is increased or decreased in accordance with the rotational movement of a rotary output shaft of a power source by directly pressing a diaphragm into contact with a diaphragm receiver.
