The invention provides a ventilation device structure of a vehicle. The ventilation device structure can fully inhibit noise outside the vehicle from entering an indoor space through an air inlet opening so as to improve silence in the vehicle. The ventilation device structure is provided with an intake opening (11), an exhaust opening (12), and a ventilation passage (13). The intake opening (11) is disposed in an interior space at the rear of the vehicle. The exhaust opening (12) exhausts air passing through the indoor space of the intake opening (11) to the outside of the vehicle. The ventilation passage (13) is formed by being surrounded by an interior member facing the indoor space and a vehicle body panel covering the outside of the interior member, and communicates the intake opening (11) and the exhaust opening (12). A shield plate (22) extending so as to intersect a noise entry path from the exhaust opening (12) toward the intake opening (11) is disposed in the middle of the ventilation passage (13).

    本发明提供一种充分地抑制车外的噪声通过进气开口向室内空间进入的情况,从而能够提高车室内的肃静性的车辆的通风设备结构。通风设备结构具备进气开口(11)、排气开口(12)及通气通路(13)。进气开口(11)配置于车辆后部的室内空间。排气开口(12)将通过了进气开口(11)的室内空间的空气向车外排出。通气通路(13)由面向室内空间的内装构件和将内装构件的外侧覆盖的车身板包围而形成,将进气开口(11)与排气开口(12)连通。在通气通路(13)的中途配置有与从排气开口(12)朝向进气开口(11)的噪声的进入路径交叉地延伸的屏蔽板(22)。
