PROBLEM TO BE SOLVED: To provide a friction reduction metal sheet unit for smoothly delivering a friction reduction metal sheet between a structural skeleton such as a caisson and the ground in the case of settling or propelling the structural skeleton in the ground or to the bottom of the sea.;SOLUTION: A roll-shaped friction reduction metal sheet 3 configured by winding a friction reduction metal sheet 2 like a roll is stored so as to be deliverable to a unit box 4, and a regulation part 5 with an open structure for regulating the relaxing of the winding of the roll-shaped friction reduction metal sheet 3 by a predetermined roll diameter or more and a granular lubricant 8 which swells when coming into contact with water, and develops friction reduction effects are installed in the unit box 4. When water gets into the unit box 4, the granular lubricant 8 swells, and the unit box 4 is filled with the swelling lubricant 8.;COPYRIGHT: (C)2013,JPO&INPIT
