PROBLEM TO BE SOLVED: To provide an elevation guiding mechanism allowing savings in a material cost resulting from its simple structure so as to lower a manufacturing cost and properly lowering an extractable part to a predetermined abutting position to a normal arrangement part in a tank without causing any horizontal swing of the extractable part in a removable submerged pump. SOLUTION: A single elevation guiding lever 7 using equal angle steel is led downward from water surface so as to be fixed to the inside of the tank so that the extractable part B is attached/detached to/from the normal arrangement part A in the removable submerged pump fixed in the tank bottom part according to an elevating/lowering operation, and engagement elements 9, 9 engaging with the elevation guiding lever 7 freely slidably from its both side parts in the opposite directions mutually are horizontally projected from the extractable part B.
