PURPOSE: A triangular safety sign having a folding support is provided to reduce manufacturing hours and expenses by integrally forming a sign, a body and a holder with injection-molding synthetic resin, and to manufacture and assemble conveniently by simplifying the structure. CONSTITUTION: A triangular safety sign(1A) is composed of three display plates(11) having reflectors in the front; a sign(10) assembling the display plates; a supporting bar(50) having the V-shaped section, and spacing the display plates from the sign; a holding unit assembled by holding the end of a supporting leg(56); and a keeping unit integrally formed to fold the support leg. Manufacturing cost and hours are reduced with integrally forming the lower display plate, the supporting bar, the holder and the keeping unit through injection molding, and assembling is convenient with simple structure. Displacement or breakage is prevented with folding and unfolding the supporting leg stably.
