The utility model relates to a not-falling road cone, comprising a hollow cone shell (11), characterized in that: the cross section of the cone shell is in the cross shape; the lower side surface (1C) of the cone shell is in the arc shape; the bottoms of two adjacent shell walls of the cone shell are connected together by a solid block (1A) or a hollow cavity filled with heavy matter, the gravity center of the whole cone shell is below the interface line of the linear side surface of the cone shell and the lower side surface (1C) of the arc shape. The road cone automatically resets to the vertical state when the road cone inclines under the exogenetic process, thus the road cone is conveniently used, the safety of the road traffic is increased and the road cone is easy to transport.
