Zusammenfassung:	To provide a notification device which can be suppressed in reduction of sound pressure.SOLUTION: A notification device comprises: a sounder 1 generating sound; and a duct 2 which is open to a vehicle lower portion, and constitutes a sound corridor releasing the sound generated by the sounder 1 to the outside of the vehicle. The duct 2 comprises a bent portion 23 between an opening 21 of the vehicle lower portion and the sounder 1. According to the notification device, an interior of the duct 2 can have simple structure while restricting damage to the sounder 1 since the sounder 1 is prevented from being hit by scattering stones and the like according to the bent portion 23 of the duct 2, and deterioration in sound pressure is suppressed.SELECTED DRAWING: Figure 1 【課題】音圧の低下を抑制できる通報装置を提供する。【解決手段】音を発生させる発音器１と、車両下部に開口して、発音器１が発生させた音を車両外部に放出する音通路を構成するダクト２と、を備え、ダクト２は、車両下部の開口部２１と発音器１との間に屈曲部２３を備える。これによれば、ダクト２の屈曲部２３によって飛び石等が発音器１に当たることが抑制されるため、発音器１の破損を抑制しつつダクト２の内部を簡素な構造とすることが可能となり、音圧の低下を抑制できる。【選択図】図１
