  • Publication number: 20110086198
    Abstract: There are provided a foaming filler member which allows, even when the inner space of a hollow member has a protruding space, easy filling of the protruding space without using an extra member, a heat-foamable sheet used for the foaming filler member, a method for manufacturing the heat-foamable sheet, and a method for filling the inner space of the hollow member. A heat-foamable sheet which extends in one direction when heated at 100 to 130° C. for 20 minutes and has an extension ratio of 5 to 50% in the extension direction is manufactured by stretch-forming a heat-foamable material. Even when the inner space has the protruding space, the protruding space can be easily filled at low cost without using an extra member by using the heat-foamable sheet as the foaming filler member, disposing the foaming filler member in the main space of the inner space, and foaming it such that the extending direction of the heat-foamable sheet is oriented toward the protruding space.
