PROBLEM TO BE SOLVED: To prevent compact properties from being impaired, and prevent chips and lubricant from being splashed out of gaps. SOLUTION: When the first and second beds 15 and 16 of a double spindle lathe provided with the first and second beds, are to be connected with each other, a sliding mechanism 31 reducing the moving resistance of the first bed, is interposed between the first bed 15 and a setting surface 20, and a connection slab 18 is disposed to the boundary part between the first and second beds 15, 16 so as to let it go across over to the first and second beds 15 and 16, and concurrently, one end part of the slab 18 is fixed to the first bed 15 side so as to be threadedly inserted into the nut part 19 of the slab 18, a draw-back bolt 20 drawing the slab 18 back to the second bed 16 side, is disposed to the second bed 16 for preventing the bolt 20 from being moved to the first bed 15 side, and the fastening of the draw-back bolt 20 thereby allows the slab 18 to be pulled up to the second bed 16 side, and also allows the slab 18 to be fixed to the second bed 16.
