<P>PROBLEM TO BE SOLVED: To provide hold-down hardware that is attached to an anchor bolt while absorbing an error caused in anchor bolt installation without hindering the screwing operation of a tightening nut. <P>SOLUTION: Hold-down hardware is protrusively provided with a tightening bushing 2, into which an anchor bolt 23 is inserted, on a surface of a backing plate 1 that is abutted on and fixed to a pillar. A projection portion 4 having a projecting amount larger than a thickness of a tightening nut 24 is provided on the backing plate 1 side in an internal portion 2' of the tightening bushing 2 so as to project from the surface of the backing plate 1 toward the internal portion 2'. A seat 3 for the tightening nut 24 to be screwed to the end of the anchor bolt 23 is constituted by the upper end of the tightening bushing 2 including a portion overlapping with the projection portion 4 at a position above it. <P>COPYRIGHT: (C)2012,JPO&INPIT |
