PROBLEM TO BE SOLVED: To provide a deer repellent sound-generating device that can generate a deer repellent sound capable of effectively repelling deer, and to provide a deer intrusion prevention system in a railroad track using the deer repellent sound-generating device, and to provide a vehicle using the deer repellent sound-generating device.SOLUTION: A deer repellent sound-generating device 10 can emit a sweep sound having frequency change with passage of time from a speaker 20 connected with the deer repellent sound generating device 10 at least in a partial frequency range of a frequency range of 1 kHz or more and 10 kHz or less. The deer repellent sound-generating device 10 is installed in an operator's cab of a train vehicle and the speaker 20 is installed in a front part of the vehicle, and a deer repellent sound is emitted during traveling of the train. Alternatively, the deer repellent sound-generating device 10 is installed around a railroad track, and the deer repellent sound is emitted from the speaker 20 to the habitat of the deer by the deer repellent sound-generating device 10. 【課題】シカを効果的に忌避することができるシカ忌避音を発生させることができるシカ忌避音発生装置ならびにこのシカ忌避音発生装置を用いたシカの線路内侵入防止システムおよび車両を提供する。【解決手段】シカ忌避音発生装置１０は、１ｋＨｚ以上１０ｋＨｚ以下の周波数範囲の少なくとも一部の周波数範囲で周波数が時間の経過に伴って変化するスイープ音をシカ忌避音発生装置１０と接続されたスピーカ２０から放鳴可能である。シカ忌避音発生装置１０を列車の車両の運転室内に設置し、スピーカ２０を車両の前頭部に設置し、列車の走行中にシカ忌避音を放鳴する。あるいは、シカ忌避音発生装置１０を線路の周辺に設置し、シカ忌避音発生装置１０によりスピーカ２０からシカ忌避音をシカの生息域に放鳴する。【選択図】図１
