Claim:
An improved structure of traffic cone, mainly to manufacture a base and a cone body of the traffic cone by stages, so the base is firstly preformed, then disposed in a mold for the injection molding of the cone body, the base is able to be formed with various counterweight according to actual needs, and the bottom surface of the base is formed with a positioning slot for positioning the mold, characterized in that: a through hole having a large dimension is formed at the center of the base, the periphery of the through hole is upwardly extended with a cone ring part having a preset height and taper, the upper portion of the cone ring part is formed with a combination part having reduced inner and outer diameter, a preset quantity of convex columnar members are installed at the circumference of the combination part and arranged with equal intervals, and a fluid passing hole is respectively formed between adjacent convex columnar members, when the cone body is injected for combing with the combination part of the base, the original material of the cone body is allowed to flow pass the inner and the outer sides through the fluid passing holes and obtain a tightly combing relation with the convex columnar members.
