PROBLEM TO BE SOLVED: To provide a weather strip capable of preventing ingress of water or the like and improving sealability when mounted on a flange, while allowing a gap between right and left lips to be narrowed, to improve retention of the flange, and to provide a manufacturing method of the weather strip.SOLUTION: A weather strip 1 includes: a grip portion 3 having a substantially U-shaped cross section, and including a bottom wall 6 and side walls 7 opposed to each other, in all of which a metal core 5 is embedded; and a hollow seal portion 2 provided at an outer peripheral surface of the grip portion 3. Inside the grip portion 3, there is formed a pressure receiving portion 4 that comprises a thermoplastic elastomer composition, and which is connected to the side walls 7. A lip 11 is formed inside of one of the side walls 7 of the grip portion 3, and a push-in portion 10 extending outward of the grip portion 3 is provided at the other side wall 7. In addition, lips 12 are formed on an outer surface of the push-in portion 10.SELECTED DRAWING: Figure 1
【課題】フランジに装着したときに水侵入等を防止して密封性を向上し、左右のリップ間の隙間を狭くしてフランジとの保持性を向上させるウェザーストリップおよびその製造方法を提供する。【解決手段】ウェザーストリップ1は金属製の芯材5を埋設した底壁6および互いに対向する側壁7からなる断面略U字状のグリップ部3と、グリップ部3の外周面に設けた中空シール部2とによって構成され、グリップ部3の内側は側壁7を連設する熱可塑性エラストマー組成物の受圧部4が形成され、さらにグリップ部3の一方の側壁7の内側にリップ11を形成し、他方の側壁7にはグリップ部3の外側へ延出する押込部10を設け、その押込部10の外側面にリップ12を形成したことを特徴とする。【選択図】図1
