To provide a vehicle side airbag device which can properly restrain a shoulder part of an occupant during a lateral collision even in a case where a door belt line is lower than the shoulder part of the seating occupant.SOLUTION: A vehicle side airbag device 20 includes an airbag 30 which is stored in a seat back 14 of a vehicle seat 10 and inflates and deploys between a seating occupant P and a side door 40. The airbag 30 is formed including: a body part 30A which restrains at least a portion of the seating occupant P from a shoulder part S to a chest part; and an extension part 30B which extends to the vehicle front side or the vehicle rear side in a part of a height area of the body part 30A (an extension height area H1). The extension part 30B overlaps with a vehicle side part member (a center pillar 50), which forms a part of a vehicle cabin side wall and protrudes to the vehicle inner side further than side glass 44, at an occupant shoulder part height area Hs in a vehicle side view.SELECTED DRAWING: Figure 2 【課題】ドアベルトラインが着座乗員の肩部がよりも低い場合においても、側面衝突時に乗員肩部を適切に拘束することができる車両用サイドエアバッグ装置を提供する。【解決手段】車両用サイドエアバッグ装置２０は、車両用シート１０のシートバック１４内に格納され、着座乗員Ｐとサイドドア４０との間に膨張展開するエアバッグ３０を備える。エアバッグ３０は、少なくとも着座乗員Ｐの肩部Ｓから胸部を拘束する本体部３０Ａと、本体部３０Ａの高さ領域の一部（延長高さ領域Ｈ１）において車両前方又は車両後方へ延長された延長部３０Ｂと、を含んで構成され、延長部３０Ｂは、車室側壁の一部を構成すると共にサイドドアガラス４４よりも車両内側へ突出した車両側部部材（センターピラー５０）と乗員肩部高さ領域Ｈｓにおいて車両側面視で重なる。【選択図】図２
