VEHICLE DOOR

To provide a vehicle door which can prevent occurrence of a malfunction where a door is unexpectedly opened at the time of lateral collision of a vehicle and can reduce in-vehicle sound of wind noise at the time of vehicle travel.SOLUTION: At least a door latch mechanism 3 is accommodated in a space formed between an outer panel and an inner panel 2 where outer peripheral edges of the outer panel and the inner panel are bonded. A resin cover 4 is arranged in the inner panel 2 to cover a work hole formed in an inner panel 2 from a cabin side. An in-vehicle sound reduction structure of the vehicle door 1 in the resin cover 4 where a cable insertion hole 4a is formed into which a latch cables 6, 7 extending from the door latch mechanism 3 are inserted includes: a nonpermeable vinyl sheet (flexible sheet material) 10 which is attached to the resin cover 4 so as to cover the cable insertion hole 4a to block outflow of air from a vehicle inside to a vehicle outside; and an insertion part 10d which is arranged in the vinyl sheet 10 so that the latch cables 6, 7 are slidably inserted into the vinyl sheet.SELECTED DRAWING: Figure 2 【課題】車両の側面衝突時にドアが不用意に開く不具合の発生を防ぐとともに、車両走行時の風切り車内音を低減すること。【解決手段】アウタパネルとインナパネル２の外周縁同士を接合して両者間に形成される空間に少なくともドアラッチ機構３を収容し、インナパネル２には、このインナパネル２に形成された作業孔を車室側から覆う樹脂カバー４を取り付け、この樹脂カバー４には、ドアラッチ機構３から延びるラッチケーブル６，７が挿通するケーブル挿通孔４ａが形成された車両用ドア１の風切り車内音低減構造を、ケーブル挿通孔４ａを覆って車内側から車外側へのエアの流出を阻止する非通気性のビニールシート（可撓性シート材）１０を樹脂カバー４に取り付けるとともに、このビニールシート１０に、ラッチケーブル６，７が摺動可能に挿通する挿通部１０ｄを設ける。【選択図】図２
