Fixed.
Similar to the fixture 3, the elastic fixing device 4 is configured so that when the elastic contact portion 38 is brought into contact with the display member 1, the protrusions 13 a and 13 b of the trunk edge 12 are recessed in the elastic contact portion 38. It is provided to be stored in 38b.
By providing in this way, when a force in the vertical direction is applied to the display member 1, the elastic contact portion 38 of the elastic fixture 4 is distorted, and the inner surface of the groove 38b is the outer surface of the ridges 13a and 13b. Therefore, further deformation of the elastic fixture 4 is suppressed, and the attachment of the elastic fixture 4 and the display member 1 is difficult to come off.

  And the elastic fixture 4 of this embodiment inserts the male screw part of the volt | bolt B2 from the outer side of one band fixing | fixed part 24a of the said support | pillar band 21 to the band through hole, and the band through-hole of the other band fixing | fixed part 24b. Further, the nut N <b> 2 is screwed by being inserted into the through-hole 39 a of the elastic fixture 4, thereby fixing the column band 21 and fixing the column band 21 to the column 2.

  In addition, similarly to the fixture 3, a cylindrical spacer 5 is preliminarily provided in each through hole 38 a and each through hole 39 a of the elastic fixture 4 of the present embodiment. By installing the spacer 5, the inner surfaces of the bolt heads of the bolts B1 and B2 and the inner surfaces of the nuts N1 and N2 abut against the edge of each spacer 5, respectively. Since the elastic fixture 4 is prevented from being deformed to a thickness less than the length of each spacer 5, each bolt / nut is tightened with an appropriate torque to make it difficult to loosen, and the mounting is continued stably. Is done.

  In the mounting structure of the road display board 11 of the present embodiment, the display member 11 has two trunk edges 12 arranged in parallel in the vertical direction, the fixture 3 is attached to the upper trunk edge 12, and the lower trunk edge 12 is mounted. Although the elastic attachment 4 is attached to the support 2 via the support band 21, the attachment 3 may be attached to the lower trunk edge 12.
