Generally, in squeeze pumps, tetrafluoroethylene is often used for the pumping tube, and since this material is weak in restoring force, the life of the pumping tube will be shortened unless the degree of compression is maintained with high precision. Therefore, as shown in FIG. 4, strict dimensional accuracy is required for the dimension h from the center to the contact surface in order to make the crushing margin of the pumping tube uniform for all needle rollers a.

The needle roller was attached to the flange part f of the rotating body with a high precision fitting between the shaft b and the needle roller. , the radial dimension i in FIG. 4 tends to vary from hole to hole, and it is extremely difficult to process this dimension i within a certain tolerance. Therefore, the dimension h in the figure is different for each needle roller a, and the degree to which the pumping tube is pressed from the inner diameter side is different, and there is also a needle roller a that crushes the pumping tube too much. There was a problem in that the pumping tube wore out prematurely, shortening its life. In addition, as shown in Fig. 5, the left and right flange portions f, f
Because the position of the hole (dimension i) varies, it is difficult to make the needle roller a parallel to the center l, and when multiple pumping tubes p are installed, the degree of compression differs from one another. There was a problem that some parts were crushed too much and wore out prematurely.
そこで、本考案は、このような問題点を解決す
