As shown in FIG. 8, in a state where the main body 1 is suspended in the vertical direction, two intersections where the outer periphery of the main body 1 intersects the longitudinal symmetry axis M are marked on the wall surface, and then the center of the main body 1, that is, The main body 1 is rotated by 90 ° about a circular hole 5b located in the middle of the three small holes constituting the display portion B5, and the horizontal symmetry axis L
Is superimposed on the two marks displayed on the wall surface (from the broken line to the solid line in the figure), the wiring device mounting frame 1
The center position of the circular hole for forming the mounting hole 2 in which the mounting hole 5 can be attached vertically can be displayed on the wall material W. That is, even when the mounting hole 2 for vertically disposing the wiring device mounting frame 15 is formed, the operation and effect can be obtained in that the hole mounting center indicator 10 can be used alone.

Next, a perforation center indicator 20 according to a second embodiment of the present invention will be described. FIG. 9 is a perspective view showing the perforation center indicator 20 of the second embodiment, and FIG. 10 is a front view of the perforation center indicator 20.

In the figure, the perforated center indicator 20 of the second embodiment has a mounting hole 2 having a shape in which four circular perforations 2a are overlapped.
The first display portion 4 'for displaying the center positions of the four circular holes 2a constituting the mounting hole 2 is divided into an upper half and a lower half. In addition, in order to be applicable even if the number of the circular perforations constituting the mounting hole 2 is six, a second display portion 5 'capable of displaying the perforation center position of each circular perforation is provided in the upper half and the lower half. The five display units arranged in the upper half and the five display units arranged in the lower half are respectively formed separately on a straight line in the horizontal direction.

The perforated center indicator 20 has a punched hole A6 'formed as a continuous bilaterally symmetrical hole having one side overlapping the horizontal symmetry axis L, and a vertical symmetry axis above the upper half. A punched hole B7 'is provided symmetrically with respect to M and formed as a discontinuous hole.

Further, the main body of the perforated center display device 20 is provided with three small contact portions 9 protruding toward the wall surface side.

Except for the three points described above, other configurations are substantially the same as those of the perforation center indicator 10 of the first embodiment described above.
