る。2. Description of the Related Art Conventionally, when a liquid is transported, it may be contained in a container such as a drum or a pail and transported. In this case, as a method of taking out the liquid in such a liquid storage container, a small-diameter opening portion in which a suction side pipe (hose, pipe, etc.) of a pump device such as a rotary pump is formed in a part of the upper surface of the container, or an upper surface is formed. It is a general method to insert the pump into an opening formed in the whole to start the pump.

に前記液体が高粘度のもの（数10p 以上）である場合、
その吸い上げは一層困難であった。However, in this method, since there is no liquid in the pump or in the suction side pipe at the time of start-up, the pump is idle, so that the liquid suction force is weak and it is difficult to suck up the liquid. Especially when the liquid is highly viscous (several 10p or more),
The siphoning was more difficult.

いない。For this reason, in such a case, it is possible to increase the suction speed by greatly increasing the rotational speed of the pump only at the time of starting, but the operation is complicated and the suction performance is limited. Therefore, it does not solve the fundamental problem.

のの構造が複雑で高価となる欠点があった。On the other hand, there is a uniaxial eccentric screw pump that transfers a liquid by inserting an elongated pump portion into an opening of a container, but the structure of the connecting portion between the pump portion and the driving portion and the pump portion itself is complicated. It had the drawback of being expensive.

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.

Can be transferred. Although a liquid having a particularly high viscosity could not be transferred by the conventional method, this invention makes it possible and the pump suction side piping is not required. Further, it is possible to provide a low-cost pump having a simple structure as compared with a conventional type pump in which a pump mechanism portion is directly inserted into a small hole for use, for example, a uniaxial eccentric screw pump.
