The purpose is to provide a mouth packer. [Structure] A cylindrical body 1 having a through hole 2 for attachment to the outside of a lock bolt is made of an elastic material, and the inside diameter of the through hole of the cylinder is formed to be equal to or smaller than the outside diameter of the lock bolt. A thin portion 3 having a diameter substantially equal to the inner diameter of the lock bolt hole to be drilled and a large diameter portion 4 are formed, and a cut surface 5 extending from the outside to the through hole is provided on the cylindrical body. .
