An automotive door-hole-sealing material reduces noise to be generated by contact between the sheeted foam elastic material and the protrusion, and, moreover, improves quietness inside the passenger compartment with high sound absorption performance and sound insulating effect. The automotive door-hole-sealing materialincludes a resin sheet, and a sheeted foam elastic material. The resin sheethas a through holeformed in association with a protruding end of the impact absorbing material. In a side view, the sheeted foam elastic materialhas a portion relaxing within an inner periphery of the through holeof the resin sheet

Automotive door-hole-sealing material

A sealing member for water cutoff is stuck to a door inner panel of an automobile for joining a door hole seal. The sealing member for water cutoff is long in length and at least a part thereof is curved when used. The sealing member for water cutoff comprises: a body part made of vulcanized sponge rubber, which is extrusion molded and having softness and elastic restoring force for reverting to an original shape when an external force once applied is unloaded; and adhesive layers formed by applying adhesive on surfaces of the body part.

Two sheets of nonwoven fabric with the same shape and size each including a rectangular bodyand a funnel-shaped projectionprojecting from one side of the bodyare stacked, and bonded together by heat welding at each side of the bodyexcept the projectionand both sides of the projection. Joint portions, andprojecting inward from a jointare located on three sides and four corners of the bodyexcept the side provided with the projection, and project to depths at which the joints do not interfere insertion of a nozzleinto a center portion of the bag. The nozzleis inserted through an openingof the projection, and the bag is filled with a granular elastic material. Then, the projectionis removed, and the opening is closed.
