Abstract
A hole plug includes a head portion and a foot portion projecting from a back surface of the head portion to be inserted into a hole to be blocked. The foot portion has a cylindrical shape formed of several uprising plates extending from the back surface of the head portion. An engaging step portion is formed at a base end of each uprising plate for holding a rim of the hole to be blocked together with the head portion. A supporting device is formed at an inside of each uprising plate for limiting bending of each uprising plate inwardly in the radial direction.
