摘要： A hole plug includes a head portion, a leg portion, and a flange portion. In a state wherein the leg portion is inserted to be locked relative to a hole of a plate material until the flange portion abuts against the plate material and is controlled, the hole plug blocks the hole. The leg portion includes an approximately cylindrical inner wall connected to the head portion; and an outer wall extending along the inner wall with a gap between the inner wall from a folded portion provided in an end portion of the inner wall, and forming a bendable thin-walled portion in one portion. The thin-walled portion is elastically bent by an external force to be capable of transitioning from a first usage condition in which the outer wall is locked in the hole with the thin-walled portion being in a non-bending state to a second usage condition in which a force larger than the first usage condition is provided to pressure contact relative to the hole.
