止装置。 The middle part of a stopper plate, which has a fulcrum for a hanging material at one end, is pivoted to the rear end of a support leg extending behind a steady rest such as a hollow pipe for sand pile construction, and the stopper plate has a fulcrum for a hanging material at one end. It is biased by a tension spring so that it rotates from the upward vertical position to a substantially horizontal stopping position with the fulcrum in front, and when it rotates to the stopping position, the other end engages the rear stopper. A fall prevention device for a steady rest such as a hollow pipe for sand pile construction, characterized in that the device is designed to protrude at a position where it fits.
