PROBLEM TO BE SOLVED: To easily adjust a distance between a wall face and a leader by fixing a fixing plate having a slit to the back of a square leader, and securing a foot part to the fixing plate with a bolt or the like. ;SOLUTION: Grip anchors or the like are preliminarily driven into an fixed to a wall at such intervals as corresponding to the positions of fixing plates 1 and 1. Then, the set bolt 23 of a foot part 2 is screwed and fixed to the grip anchor, and the side plates 21 of the foot part 2 are brought into contact with the external surface of the plates 1 and 1. In this case, fixing holes 22 are positionally aligned with slits 12. Then, a bolt is passed through the holes 22 and the slits 12 from the outside, and screwed to a nut 32, thereby being tightened and fixed. As a result, the bolt, when loosened and moved in a back and forth direction, can slide in the same direction within the range of the slits 12. According to this construction, a leader can be erected under the adjustment of a distance from a wall, and can be vertically provided even at such a wall position as having an undulation, thereby eliminating a concern about the occurrence of a play or a gap at a leader joint part.;COPYRIGHT: (C)1998,JPO
