Claims

[Claims for Utility Model Registration] (1) It consists of a main stopper and two types of auxiliary stoppers, and the main stopper is a long and thin strip material, and both longitudinal ends and the lower end thereof are wedge-shaped. The wedge-shaped region has several rows of locking protrusions that are substantially perpendicular to the longitudinal direction of the strip material, and the ends of the strip material having these several rows of locking projections are provided on both sides of the wedge-shaped region. Both sides of the strip material in between have multi-stage locking protrusions parallel to the longitudinal direction, and the two types of auxiliary stoppers are both thin plate materials shorter in length than the main stopper, One type of auxiliary stopper has both ends and a lower end shaped like a wedge, and has horizontal multi-step locking protrusions on both sides of the intermediate part. A stopper for preventing movement of a manhole iron cover, which is formed into a wedge shape only at the lower end and has horizontal multi-stage locking protrusions on both sides opposite one end. (2) The stopper for preventing movement of a manhole iron cover according to claim 1, wherein the band plate material and the thin plate material are both made of a polymeric composite material made of a hard and elastic synthetic resin material. .
