To make easier attachment and detachment of a supporting member and facilitate replacement of a light bulb by providing a holding piece inside a road sign equipment body and fitting in a plug-in hooking piece of the flexible supporting member to which a light bulb is attached by providing the holding piece.

A hollow sign section 1 of a roughly conical form and a pedestal section 2 are formed integrally. A holding piece 3 which holds a light bulb supporting section 11 is provided at the underside inside the pedestal 2. A plug-in hooking piece 12 of a sheet form is provided at the lower end of the supporting member 11, so that a hole 13 in the hooking piece 12 and a male part 4 for hooking provided in the holding piece 3 may be fitted in with each other. The supporting member 11 including the plug-in hooking piece 12 is formed of a flexible material such as a plastic. When the plug-in hooking piece 12 is to be fixed, the plug-in hooking piece 12 is pushed into the peripheral direction of the pedestal 2 and the hooking male part 4 and the hole 13 of the plug-in hooking piece 12 are fitted in with each other and fixed. To remove the plug-in hooking piece 12 from the body, the plug-in hooking piece 12 is pulled out in a flexed state. Then it can be easily removed from the body and thereby makes replacement of a light bulb easy.
