To provide a wind direction adjustment device for reducing ventilation resistance in a ventilation path.SOLUTION: A wind direction adjustment device 1 comprises: a case body 10 having a ventilation path C; a rectangular plate-shaped fin 20 arranged inside the ventilation path C, and rotatable about a central axis AX parallel to a first principal plane 21 or a second principal plane 22; and a flat operation knob 30 that is integrated with the fin 20 in a thickness direction, and is made thicker than a thickness T1 of the fin 20. The operation knob 30 has a narrow part 36 formed by at least parts of two side wall parts 35 that are continuous with the respective fins 20. Regarding a width of the fin 20 in a direction along a central axis AX, a width W2 of the narrow part 36 is made narrower than a width W3 of a leeward end part 33 of the operation knob 30.SELECTED DRAWING: Figure 1
【課題】通風路での通気抵抗を低減する風向調整装置を提供する。【解決手段】風向調整装置1は、通風路Cを有するケース体10と、通風路Cの内部に配置され、第1主平面21又は第2主平面22に対して平行な中心軸AXを基準として回動可能な矩形板状のフィン20と、フィン20に対して厚み方向で一体化され、フィン20の厚みT1よりも厚い平型の操作ノブ30とを備える。操作ノブ30は、各々フィン20と連続する二つの側壁部35の少なくとも一部同士で形成される狭小部36を有する。フィン20の中心軸AXに沿った方向での幅について、狭小部36の幅W2は、操作ノブ30の風下側端部33の幅W3よりも狭い。【選択図】図1
