Further, the operator rotates the rotor 80 of the runner construction assisting tool 40 to the support position to temporarily fix the runner 20 to the ceiling 11, and drives a screw into the runner 20 to fix the runner 20 to the ceiling 11. .. Therefore, the runner construction assisting tool 40 can facilitate the work of the operator attaching the runner 20 to the ceiling 11.

The rotor 80 is located on the opposite side of the rod-shaped portion 34 of the erection member 30 with the main body plate 56 interposed therebetween. Therefore, when the operator rotates the rotor 80 in the work of fixing the runner 20 to the ceiling 11, the erection member 30 does not get in the way.

Further, in the present embodiment, the coil spring 83 can be held by the bolts 44 and 45, and the slide member 82 can be slidably held along the extending direction 18. Further, the second nut 47 fastened to the bolts 44 and 45 prevents the slide member 82 from sliding beyond the protruding position. That is, the coil spring 83 can be held, the slide member 82 can be held, and the slide can be regulated with a simple structure of bolts and nuts.

The temporary placing plate 100 is fixed to the rotating plate 84 of the rotating element 80, and when the rotating element 80 is in a non-supporting position, the runner 20 is in a posture in which the runner 20 can be temporarily placed. That is, when the runner 20 is temporarily placed on the temporary placing plate 100, the rotor 80 is always in the non-supporting position. When the rotator 80 is in the support position, the rotator 80 interferes with arranging the runner 20 on the ceiling 11, but since the rotator 80 is always in the non-support position, the runner 20 is placed on the ceiling 11. The rotor 80 does not get in the way when it is placed in the ceiling. That is, when the rotor 80 is in the non-supporting position, the runner 20 can be temporarily placed on the temporary placing plate 100, so that the operator arranges the temporarily placed runner 20 on the ceiling 11 and temporarily fixes the runner 20. Work can be done smoothly.
