PROBLEM TO BE SOLVED: To provide a hole plug capable of being fixed to various holes.SOLUTION: A hole plug 10 includes a body 12 with a center opening part 20, a fixation member 24 configured to fix the body to a hole of a workpiece, and an annular foaming layer 40 attached to the body and foaming into the hole to form liquid-tight shielding. The fixation member is formed so as to be pushed into the hole, upon fixing the hole plug to the hole. The fixation member is, upon fixing the hole plug to the hole, engaged to an inner edge part of the hole at various radius positions according to a diameter of the hole; receives force radially inward from the inner edge part of the hole, and thereby resists extraction from the hole.SELECTED DRAWING: Figure 1

    【課題】様々な寸法の穴に固定できる穴プラグを提供すること。【解決手段】穴プラグ10が、中心開口部20を有した本体12と、本体をワークの穴に固定する固定部材24と、本体に取り付けられた環状の発泡層40であって、穴内に発泡して液密の遮蔽を形成する発泡層とを具備し、固定部材は、該穴プラグを穴に固定する際に、該穴内に押入されるように形成されており、該固定部材は、該穴プラグを穴に固定したときに、該穴の直径に応じて様々な半径位置で同穴の内縁部と係合して、同穴の内縁部から半径方向内側に力を受け、同穴から抜去されることに抵抗するようになっている。【選択図】図1
