US 2006/0140688 A1 · Foam filling member

Abstract

A foam filling member that can hold a foam sheet in a looped shape stably, without increasing the number of components, to provide improved vibration suppression and sound insulation. The strip-like foam sheet is formed in a looped shape by bending round it, so that both end portions of the foam sheet are overlapped with each other in a thickness direction thereof to form an overlapped portion therein. Then, insertion shafts of a clip are inserted through the overlapped portion, so that the overlapped portion is held in sandwich relation between a base portion and a head portion to form a foam filling member. Then, a supporting portion of the fixing portion of the clip is inserted in a fixing hole of an inner panel and fixed to the inner panel. After the inner panel and an outer panel are welded, the foam filling member is foamed, cross-linked, and cured by heating in a drying line process at the baking finish, to thereby produce the foam, whereby the interior space of the pillar is filled up with the foam, leaving no space therein.
