Abstract: The present invention relates to a roly poly type bollard. The bollard comprises a bollard body unit and an embedment unit. The embedment unit comprises a metallic pipe connection unit and a metallic pipe for installing the bollard on a sidewalk by being connected to the metallic pipe connection unit. A part of the metallic pipe connection unit can be separated from the metallic pipe when the bollard body unit is folded due to shock. A fixture in which an inverted triangle frame with three or more space units is repeated is inserted and attached to an inner cylinder of the metallic pipe connection unit so that the fixture is filled with an adhesive or mortar. According to the present invention, the bollard is formed of a synthetic resin, and the embedment unit is combined so that the embedment unit cannot be separated from the metallic pipe. Even when a tire of a vehicle runs over the bollard, the upper part of a cylindrical connection unit is separated from the metallic pipe for a short time, but the bollard maintains a sturdy installation state without being separated from the metallic pipe. Accordingly, the bollard can largely save maintenance costs.
