PROBLEM TO BE SOLVED: To facilitate attachment by inserting a bushing fixed onto the base of a plate part into the hole of a supporting wall, rotating a holding pin mounted on the bushing and engaging the pin with the wall of the hole. SOLUTION: When an operating plate 35 is moved to an upright mounting position shown in a broken line, a holding pin 4 can be rotated. The tapping screw thread 29 of a disk 28 bites into the mounting hole of a supporting wall at the position while the attachment device is further drawn into the mounting hole by the spiral arrangement of the crew thread 29. When the plate 35 is turned in the direction of the arrow G and superposed to an attachment flange 2 and moved in the direction of the arrow H, the plate 35 is at a constructional position. Accordingly, the fitting part can be fitted simply without requiring special tools. |
