PROBLEM TO BE SOLVED: To increase sealability without deteriorating a door closing property of a vehicular weather strip.SOLUTION: A weather strip 1 has a hollow seal part 3 attached to either a door opening 21 or a door 25 that opens or closes the door opening, and brought into contact with a projected edge 22 of a vehicle body 20 when the door is closed, which is in a collapsed state changed from a natural state when a lid body is opened. A separate hollow tube 7 formed of a polymeric material, and having a flat pipe shape in which a gap is generated in a collapsed direction with respect to the inner surface of a hollow seal part 3 at least in the natural state, is inserted in the hollow seal part 3. A vehicular weather stripper comprises a pressure device that makes the hollow tube 7 bulge from the flat pipe shape by pressurizing a fluid in the hollow thereof, and presses the hollow tube onto the inner surface of the hollow seal part 3 in the collapsed state.SELECTED DRAWING: Figure 1
【課題】乗物用ウエザストリップのドア閉まり性を低下させないで、シール性を高める。【解決手段】ウエザストリップ1は、ドア開口部21又はそれを開閉するドア25のいずれか一方に取り付けられ、蓋ドア開け時の自然状態からドア閉め時に自動車ボディ20の凸縁22に当接して圧潰状態となる中空シール部3を有する。中空シール部3の内側に、少なくとも自然状態の中空シール部3の内面に対して圧潰方向に隙間が生じる偏平管形状をなす、高分子材料よりなる別体の中空チューブ7が挿入されており、ドア閉め後に、中空チューブ7を、その中空内の流体を加圧して偏平管形状から膨らませ、圧潰状態の中空シール部3の内面に押し当てる加圧装置が設けられている。【選択図】図1
