To provide an air blowout device capable of elongating an arrival distance of air flow.SOLUTION: An air blowout device 50 includes a duct part 52 forming an air flow passage 520 through which air flow passes, and having an outlet 522 of the air flow opened on the downstream side of the air flow passage 520, and a pulsatile flow generation part for generating pulsatile flow by repeating acceleration and deceleration of the air flow passing though the air flow passage 520. In the pulsatile flow generated from the pulsatile flow generating part, a deceleration time of the air flow is not shorter than an acceleration time of the air flow.SELECTED DRAWING: Figure 7

    【課題】気流の到達距離を長くすることが可能な空気吹出装置を提供する。【解決手段】空気吹出装置50は、気流が通過する空気流路520を形成するとともに空気流路520の下流側に気流の吹出口522が開口するダクト部52と、空気流路520を通過する気流の加速および減速を繰り返すことで脈動流を発生させる脈動流発生部と、を備える。そして、脈動流発生部が発生させる脈動流は、気流の減速時間が気流の加速時間以上となっている。【選択図】図7
