PROBLEM TO BE SOLVED: To achieve an unlock state of a door to a vehicle body more reliably after a predetermined time has elapsed from the time of a vehicle collision.SOLUTION: An unlock device of a vehicle door comprises: a lock device 15 for locking or unlocking a door 5, which closes a door opening 4 openably, to a vehicle body 2; and an operation device 25 for inputting a detection signal from a sensor 20 for detecting a collision situation of a vehicle 1, and operating the lock device 15 so as to perform the unlock operation. The operation device 25 comprises: a control device 26 for inputting the detection signal; an ignition device 34 which is ignited by the control based on the detection signal input by the control device 26; an expansion material 35 which expands by combustion; an operation body 37 for allowing the lock device 15 to perform the unlock operation by the pressure of the expanded expansion material 35; and a combustion material 38 for time delay provided between the ignition device 34 and the expansion material 35, for combusting the expansion material 35 after the lapse of a predetermined time during which the combustion progresses from the start of the combustion due to the ignition of the ignition device 34.

    【課題】車両の衝突時から所定時間経過後にドアを車体に対しアンロック状態にさせることが、より確実に達成できるようにする。【解決手段】車両用ドアのアンロック装置は、ドア開口4を開閉可能に閉じるドア5を車体2に対しロック、アンロック可能とするロック装置15と、車両1の衝突状況を検出するセンサー20からの検出信号を入力してロック装置15をアンロック動作させるよう作動する作動装置25とを備える。作動装置25が、検出信号を入力する制御装置26と、制御装置26が入力した検出信号に基づく制御により発火する発火装置34と、燃焼により膨張する膨張材35と、膨張した膨張材35の圧力によりロック装置15をアンロック動作させる作動体37と、発火装置34と膨張材35との間に介設され、発火装置34の発火により燃焼が開始されて燃焼が進行する所定時間の経過後に膨張材35を燃焼させる時間遅延用燃焼材38とを備える。【選択図】図1
