To enable pedestrians or the likes to hear notification sound even if an opening of a duct facing the ground surface side is closed.SOLUTION: A vehicle approach notification sound generator 10 includes: a speaker 22 which is attached to a vehicle and emits notification sound to the outside of the vehicle; an opening 40 which emits the notification sound to the outside of the vehicle; and a duct mechanism 20 which allows the opening 40 and the speaker 22 to communicate through a first communication hole 64. The vehicle approach notification sound generator 10 has multiple small holes 74 provided in a direction different from the opening 40 and includes a second communication passage 80 which allows the small holes 74 and the duct mechanism 20 to communicate with each other.SELECTED DRAWING: Figure 2

    【課題】地面側に臨むダクトの開口部が閉塞された場合であっても、歩行者等が報知音を聞きとることができること。【解決手段】車両接近報知音発生装置10は、車両に取り付けられて車外に向かって報知音を発するスピーカ22と、車外に向かって報知音を放出する開口部40と、第1連通孔64を介して開口部40とスピーカ22とを連通させるダクト機構20とを備え、開口部40と異なる方向に設けられた複数の小孔74を有し、複数の小孔74とダクト機構20とを連通させる第2連通路80を備えている。【選択図】図2
