PROBLEM TO BE SOLVED: To provide a lower bearing structure of a screw storage pump having less wear in a rotation sliding surface, and the long life time as a bearing. SOLUTION: In the lower bearing structure of the screw storage pump, the water is pumped up through a tilted trough 16 as a channel by rotating a screw shaft arranged along the inner surface of a tilted trough 16 combining a low place and a high place. A fixing support shaft 110 is inserted into a recess 102 formed at the lower end side of a screw shaft 100. The inside surface of a bush 104 fitted into the recess 102 is made to be the rotation sliding surface for a sleeve 112 installed in the fixing support shaft 110. COPYRIGHT: (C)2006,JPO&NCIPI
