To provide a vehicle defroster device which can efficiently blow out the air-conditioning air to a wide range of a front windshield glass.SOLUTION: A defroster device comprises: an air-conditioning unit; a defroster blowout port 11; and a connection duct 12. The defroster blowout port 11 is arranged in a center region in a vehicle width direction below and in front of the front windshield glass so as to extend in the vehicle width direction and blows out an air-conditioning air toward the front windshield glass from a vehicle interior side. The connection duct 12 connects the air-conditioning unit to the defroster blowout port 11. The connection duct 12 has a chamber 17 with a passage width in a direction orthogonal to the vehicle width direction being wider than a passage width of a downstream end region in a blowout direction of the air-conditioning air. The chamber 17 is formed in a swollen shape that swells out toward a downstream side in the blowout direction of the air-conditioning air as proceeding toward the center region from one end side and the other end side in the vehicle width direction.SELECTED DRAWING: Figure 4

    【課題】フロントウインドシールドガラスの広範囲に効率良く空調空気を吹き出すことができる車両のデフロスタ装置を提供する。【解決手段】デフロスタ装置は、空調ユニットと、デフロスタ吹き出し口11と、接続ダクト12と、を備えている。デフロスタ吹き出し口11は、フロントウインドシールドガラスの前部下方の車幅方向の中央領域において車幅方向に延びて配置され、フロントウインドシールドガラスに向けて車内側から空調空気を吹き出す。接続ダクト12は、空調ユニットとデフロスタ吹き出し口11を接続する。接続ダクト12は、車幅方向と直交する方向の通路幅が、空調空気の吹き出し方向の下流端領域の通路幅よりも広いチャンバ17を有する。チャンバ17は、車幅方向の一端側と他端側から中央領域に向かって空調空気の吹き出し方向の下流側に膨出する膨出形状に形成されている。【選択図】図4
