PROBLEM TO BE SOLVED: To provide a fitting capable of confirming the existence of a construction error only by rotating a fitting body in the opening-closing direction after construction.SOLUTION: The fitting can sense and confirm the existence of the construction error only by rotating the fitting body 3 in the opening-closing direction after the construction, by rotatably installing the fitting body 3 in the depth direction in a jamb 2 by pivot hinges 4 and 5, forming an interference part 7 on an outside surface 32a of a semicircular arc shape of a suspender side stile 32 of the fitting body 3, installing a sensing part 6 on an inside surface 22a of a suspender side stile 22, and generating a sound squeak when the interference part 7 interferes with the sensing part 6 when there is the construction error, so as not to generate the sound squeak when the interference part 7 rotates by having a clearance with the sensing part 6 when there is no construction error when rotating the fitting body 3 in the opening-closing direction. |
