PROBLEM TO BE SOLVED: To provide a unit lifting fitting capable of easily and smoothly tightening and fixing a bolt member for lifting to a nut member attached to the lower face of an upper frame member to perform the lifting work of a housing unit quickly. SOLUTION: This unit lifting fitting 14 is used to lift the housing unit 10 by attaching it to the housing unit 10. It is composed of a base plate member 24 which is provided along the lower face of the upper frame member 16 constituting the housing unit 10 and to which the nut member 23 is integrally fixed and a screw/bolt member 17 which has a lower male screw 25 and an upper male screw 18, screw-fit the lower male screw 25 in the nut member 23, and protrude the upper male screw 18 above the upper frame member 16. The screw diameter of the lower male screw 25 is larger than the screw diameter of the upper male screw 18. The screw diameter of the upper male screw 18 is such a size that it is fitted in play and is inserted into a screw hole of the nut member 23. COPYRIGHT: (C)2004,JPO
