Abstract
A support post structure includes: a ground plate mounted on a support post anchor driven into the ground or a concrete base; a support post; a universal joint for tiltably supporting a lower end of the post; a lower support plate placed on an upper end of the post; a spring; an upper support plate; a bolt inserted through the lower support plate, the spring, and the upper support plate; a nut threaded into the bolt; and a rope hanging between a mooring part of the bolt and a predetermined position near the lower end of the post. The support post is brought to a standing state when the rope is tightened by the nut and is tiltable in all directions when a guard fence receives a falling rock or the like, autonomously restoring to the initial standing state when the rock is removed.
