PROBLEM TO BE SOLVED: To provide an angle adjusting metal fitting capable of reliably blocking the backward rotation of the other metal fitting relative to one metal fitting and reducing the size.SOLUTION: An angle adjusting metal fitting 10 comprises a backing plate part 3a, a second metal fitting 9 and a wedge member 7. The backing plate part 3a is arranged orthogonally with respect to the peripheral edge part of the second metal fitting 9. The wedge member 7 is so arranged in a wedge-shaped clearance 5 between the backing plate part 3a and the peripheral edge part of the second metal fitting 9 as to move in the longitudinal direction of the wedge-shaped clearance 5. Moreover, a ventral face of the wedge member 7 meshes with the peripheral edge part of the second metal fitting 9, and a back face 7c thereof is received in abutment by a plate surface 3k of the backing plate part 3a thereby to block the backward rotation of the second metal fitting 9. |
