Abstract: The present invention relates to a rotary bollard for preventing the entry of a vehicle and a motor, which is specialized in entry prevention of a motor (motorcycle), and allows smooth passage of pedestrians by inducing one-way traffic while a bollard is only rotated to one side. The conventional bollard cannot properly perform an original function since a motor (motorcycle) can freely enter between bollards, and causes a problem of degrading the constructability since a lot of time and personnel for the underground burying construction are required due to the need for a large quantity of bollards even though the bollards are installed at intervals that secure passage by pedestrians and strollers since the bollards are formed in a vertical pillar shape. To this end, according to the present invention, the entry of a motor is prevented while maintaining a closed state of a bollard of a gate scheme, which is continuously installed, and when a pedestrian or stroller pushes the rotary bollard to move forward, the rotary bollard is temporarily rotated and opened, thereby allowing smooth passage.
