Next, as shown in FIG. 8, when the pressing body 5 is pressed in the wall surface H direction with a finger, the stop needle 4 protruding from the pressing body 5 protrudes from the needle hole 3 of the accommodating recess 2, and this stop is formed. The needle 4 pierces the wall surface H. In the illustrated one, it is assumed that the stop needles 4 are projected at two places of the pressing body 5, so that the gauge body 1 is positioned on the wall surface H in the state where the two stop needles 4 are pierced into the wall surface H. It can be stopped so that it does not move.

Therefore, if the outer line of the gauge body 1 positioned on the wall surface H is copied onto the wall surface H, the position where the rectangular square hole having a length of 95 mm and a width of 51 mm is formed can be accurately marked. .. In this case, if the hand that does not copy the outline of the gauge body 1 is attached to the gauge body 1 and the drawing is performed, the outline of the gauge body 1 can be easily drawn and the workability is improved.

Therefore, in the injured gauge of the present invention, the gauge body 1 does not slide and move, and it is not necessary to keep the gauge body 1 in a state of being held by hand, so that the work of adding the contour mark becomes very easy. ..

Further, in the injured gauge of the present invention, the horizontality and verticality of the gauge body 1 can be easily confirmed by the bubble moving portion 8 at the time of the work of attaching the contour mark, and the contour mark can be attached accurately and promptly. Will be possible.

Further, in the injured gauge of the present invention, when the work of attaching the contour mark is completed, if the gauge body 1 is held with one hand and pulled away from the wall surface H, the stop needle 4 stuck in the wall surface H is accommodated by the coil spring 6. Since it is pulled back to 2 and does not protrude from the needle hole 3, it can be safely handled during storage, transportation, and the like.
