To provide a technique that enables a heat generation device to be stably mounted on a mating member with a small number of components.SOLUTION: A variable vent mechanism is provided with: an airbag having a vent hole 21 in an opening shape on a bag wall surface; a flap 4 mounted on the airbag to cover the vent hole 21, at a first fixed part 41; a strap 5 that is extended from a connection end part 43 of the flap 4 to be positionally fixed to a closing position where the vent hole 21 is closed, at a second fixed part 52; and a closing release device that releases the strap 5 and changes a position of the flap 4 from the closing position. A relation between a maximum length L3 between the first fixed part 41 and the connection end part 43 in a first direction in which the first fixed part 41 is joined to the second fixed part 52 and a maximum length L4 of the first fixed part 41 in a second direction which is orthogonal to the first direction satisfy a relational expression of 0.5≤L3/L4≤3.0, where the length in the second direction is shorter at the connection end part 43 than at the first fixed part 41.SELECTED DRAWING: Figure 3

    【課題】発熱装置を相手部材に対して少ない部品点数で安定的に取付け得る技術を提供すること。【解決手段】袋壁面に開口状のベントホール21を有するエアバッグと、第1固定部41において前記エアバッグに取付けられ前記ベントホール21を覆うフラップ4と、前記フラップ4の接続端部43から延び、第2固定部52において前記ベントホール21を閉じる閉位置に位置固定するストラップ5と、前記ストラップ5を自由状態とし前記フラップ4を前記閉位置から位置変化させる閉解除装置とを具備し、前記第1固定部41と前記第2固定部52とを結ぶ第1方向における前記第1固定部41と前記接続端部43との最大長さL3と、前記第1方向に直交する第2方向における前記第1固定部41の最大長さL4との関係は、0.5≦L3/L4≦3.0を満足し、前記第2方向の長さは、前記接続端部43側において前記第1固定部41側よりも短い、可変ベント機構。【選択図】図3
