is the predetermined screwing position 8 of the mounting screw in the mounting groove 5,
The mounting groove 5 has a head insertion hole 9 for the mounting screw in the mounting groove 4.
It is formed into an arc shape with radii r 1 and r 2 of the same length, respectively, with the center at . When installing this base on a ceiling surface, etc., first attach both mounting screws 3, 3 to the desired mounting positions on the installation surface 2, and after adjusting them slightly, insert one of the mounting screws 3 into the insertion hole 9 of the base 1. Pass the head of the other mounting screw 3 through the insertion hole 10, which is wider than the insertion hole 9. The insertion hole 10 is wide and allows the head of the mounting screw 3 to be inserted easily even if it is in the shadow of the base 1. First, the base body 1 is rotated around the mounting screw 3 passed through the insertion hole 9, and the mounting screw 3 passed through the insertion hole 10 is placed at a predetermined screwing position 8. Next, attach the base 1 to the predetermined screwing position 8.
Rotate around the mounting screw 3 located in the insertion hole 10.
The position of the mounting screw 3 passed through is set as the predetermined screwing position 11 of the mounting screw, and after confirming that the base body 1 is at the position where it should be fixed, both the mounting screws 3 are tightened.
