The purpose is to obtain a pump device that has a simple structure and that does not require priming operation. For that purpose, a structure is required in which the priming operation is completed when the pump part is inserted. In consideration of the application, it is necessary to insert the pump portion into the liquid storage container through a hole having a small diameter like a mouth of a drum can. Therefore, it is important to form the pump portion as small as possible.
