Title:
HOLE PLUG
Document Type and Number:
WIPO Patent Application WO/2012/161033
Kind Code:
A1
Abstract:
This hole plug comprises: a main tube to be inserted into a mounting hole formed on a mounted member to block the mounting hole; a large umbrella-shaped flange extending from an opening end of the main tube toward the outer periphery; a secondary tube which is disposed on the inside of the main tube, and has an opening end in a direction inverse to that of the main tube; and a small umbrella-shaped flange extending from the opening end of the secondary tube toward the outer periphery. The mounted member mounted onto the main tube is sandwiched between the large umbrella-shaped flange and the small umbrella-shaped flange, and therefore there can be improved water-tightness without any increase in insertion force.
