This invention relates to a vehicle ion generating device, of the duct wall from the outside of the duct of the vehicle air conditioning system against the mounting body fixed inside the lower part of the window is doedoe protrudes the duct to the exposed surface that is exposed to the air flowing through the air conditioning duct is spaced a predetermined interval from each other and having a plurality of electrode supporting through-hole is formed in the center And a vehicle according to the ion generating device inserted through one side of the ball fixed and the other end is extended to the lower side of the inner duct generates a respective positive and negative ions which comprises a plurality of electrodes spaced from each other a certain distance of the electrode supporting , and at the exposed surface of the electrode supporting body moisture is generated by the temperature difference between the duct and the body / electrode characterized in that the aggregation-preventing means are provided such that water droplets drip into the duct without mungchiji inside each other. Thus, the exposed surface of the electrode supporting body, as well as, or a portion thereof connecting the structure to the surface, or, out of the air inside the duct to form an inlet hole to the outside through the duct to be introduced into the duct so that the exposed surface Body / by the moisture generated by the temperature difference between the electrodes so that the dripping water to one another in the duct without mungchiji exposed surface of the electrode supporting body, such as a spark discharge phenomenon and noise due to the electrode block in advance that the conduction is generated between the electrodes to obtain the effects such as being able to prevent the occurrence of.본 발명은 차량용 이온발생장치에 관한 것으로서, 차량용 공조시스템의 덕트의 외부에서 덕트벽면의 설치창에 밀착 고정되고 공조용 에어가 흐르는 덕트 내부로 노출되는 노출면에 이 덕트의 내부 하방으로 돌출되되 서로 일정간격 이격되며 중앙에 관통공이 형성된 복수의 전극지지부를 갖는 본체 및 상기 전극지지부의 관통공에 일측이 삽입 고정되고 그 타측이 덕트 내측의 하방
