Zusammenfassung:	PURPOSE: A bollard for vehicle entry prevention is provided to restore a post body projected to the ground to the original position reliably, to be lightweight and to have excellent strength, and to bend elastically against the collision of an outside object quickly. CONSTITUTION: A bollard for vehicle entry prevention comprises: a post body(10) projected from the ground to make direct contact with an outside object and a vehicle; a holder(16) fixed to the bottom of the post body; a universal joint(20) supported with a 1-axis(22) to support the post body; a cylinder(30) buried under the ground to house the universal joint to be slidable; and a compression spring(40) having one end fixed to a 2-axis(26) and the other end fixed to the cylinder to provide elastic restoring force to the universal joint.
