[0066] 6 to 10, in a state where the plate back surface Pb on the plate inner surface Pd side is in contact with each of the third protrusions 63, the plate inner surface Pd side is pressed against each of the third protrusions 63 from the leg front surface 5 side, and while each of the third protrusions 63 is elastically deformed toward the leg back surface 6 side (each of the fourth protrusions 64 side), the plate inner surface Pd side is inserted between each of the third protrusions 63 and each of the fourth protrusions 64 protruding into the plate insertion hole 31 (plate insertion interval δ2). By pressing against each of the third protrusions 63, the plate inner surface Pd side of the reflector P1 slides over each of the third protrusions 63 while elastically deforming each of the third protrusions 63 toward the leg back surface 6 side (each of the fourth protrusions 64 side), and gets over each of the third protrusions 63 to be inserted between each of the third protrusions 63 and each of the fourth protrusions 64 protruding into the plate insertion hole 31.

[0070] As shown in Figure 10, with the plate back surface Pb on the plate inner side surface portion 56B side abutting against the third protrusion 63, the other reflector portion 56 is pressed against the third protrusion 63 from the leg front surface 5 side, elastically deforming the third protrusion 63 toward the leg back surface 6 side (toward each fourth protrusion 64), while inserting the plate inner side surface portion 56B side between the third protrusion 63 and the fourth protrusion 64 protruding into the other plate insertion hole portion 32 (plate insertion spacing δ2).

[0071] As shown in Fig. 10, the other reflector 56 is inserted (attached) into the other plate insertion hole 33 by inserting (disposing) the plate outer side surface 56A side between the first protrusions 61 and the second protrusions 62 protruding into the other plate insertion hole 33 and inserting (disposing) the plate inner side surface 55B side between the third protrusions 63 and the fourth protrusions 64 protruding into the other plate insertion hole 33.

[0072] 9 and 10, the reflector P1 (display plate) inserted into the plate insertion hole 31 has its plate inner side Pd pressed against the third protrusions 63 protruding into the plate insertion hole 31, and while the third protrusions 63 are elastically deformed toward the leg surface 5, the plate inner side Pd is pulled out from between the third protrusions 63 and the fourth protrusions 64, and the plate outer side Pc is pulled out from between the first protrusions 61 and the second protrusions 62, and is removed from the plate insertion hole 31. The plate inner side Pd of the reflector P1 is pressed against the third protrusions 63, and while the third protrusions 63 are elastically deformed toward the leg surface 5, the reflector P1 slides over the third protrusions 63, and is removed from between the third protrusions 63 and the fourth protrusions 64.

[0073] As shown in Figure 9, one of the reflecting plate portions 55 inserted into one of the plate insertion hole portions 32 has its inner plate side portion 55B pressed against the third protrusion 63 protruding into one of the plate insertion hole portions 32, elastically deforming the third protrusion 63 while the inner plate side portion 55B side is pulled out from between the third protrusion 63 and the fourth protrusion 64 and the outer plate side portion 55A side is pulled out from between the first protrusions 61 and second protrusions 62 protruding into one of the plate insertion hole portions 32, and the reflecting plate portion 55 is removed from one of the plate insertion hole portions 32.

[0074] As shown in Figure 10, the other reflecting plate portion 56 inserted into the other plate insertion hole portion 33 has its inner plate surface portion 56B pressed against the third protrusion 63 protruding into the other plate insertion hole portion 33, elastically deforming the third protrusion 63, and its inner plate surface portion 56B pulled out from between the third protrusion 63 and the fourth protrusion 64, and its outer plate surface portion 56A pulled out from between the first protrusions 61 and second protrusions 62 protruding into the other plate insertion hole portion 33, and is then removed from the other plate insertion hole portion 33.

[0075] As shown in Figures 9 and 10, the plate holder Z elastically deforms the protrusion toward the leg front surface 5 or the leg back surface 6, thereby holding the reflector P1 (each reflector portion 55, 56) within the plate insertion hole 31 (each plate insertion hole portion 32, 33) so that it can be freely removed (attached and detached) from the plate insertion hole 31 (each plate insertion hole portion 32, 33). The plate holder Z clamps the outer plate surface Pc side of the reflector P1 (the outer plate surface portions 55A, 56A side of each reflector portion 55, 56) with each of the first protrusions 61 and each of the second protrusions 62, and clamps the inner plate surface Pd side of the reflector P1 (the inner plate surface portions 55B, 56B side of each reflector portion 55, 56) with each of the third protrusions 63 and each of the fourth protrusions 64, thereby holding the reflector P1 (each reflector portion 55, 56) within the plate insertion hole 31 (within each plate insertion hole portion 32, 33).

Each pipe end of each of the single pipes PU, PU is held by the first clamps K1, K1 of each of the barricade legs X1, X1 and held by the second clamps K2, K2 of each of the barricade legs X1, X1.

[0079] In each barricade leg X1, X1, the first clamp K1, K1 inserts a single pipe PU into a pipe insertion hole 49 between the clamp body 45 and the clamp opening / closing part 46, as shown in Fig. 11, and grips the single pipe PU with the clamp body 45 and the clamp opening / closing part 46. The first clamp K1 rotates the clamp nut 48 about the clamp screw shaft 47 and presses it against the clamp opening / closing part 46, thereby gripping the single pipe PU with the clamp body 45 and the clamp opening / closing part 46. The second clamp K2, K2 inserts a single pipe PU into the pipe insertion hole 49 between the clamp body 45 and the clamp opening / closing part 46, and grips the single pipe PU with the clamp body 45 and the clamp opening / closing part 46.
