PROBLEM TO BE SOLVED: To provide an angle adjustment fitting capable of infallibly preventing inverse turning of one metal fitting with respect to the other metal fitting and achieving downsizing.SOLUTION: An angle adjustment fitting 10 comprises: a first metal fitting 1 having a backing plate 3a; a second metal fitting 9; and a wedge member 7. The backing plate 3a is disposed to face a gear part 9c of the second metal fitting 9. The wedge member 7 is disposed in a wedge-like clearance 5 between the backing plate 3a and the gear part 9c to be movable in the length direction of the wedge-like clearance 5. The wedge member 7 has a tooth part 7b engaged with the gear part 9c, and a back face 7c received by coming into contact with a plate surface 3k of the backing plate 3a. This configuration prevents inverse turning of the second metal fitting 9. |
