The present invention relates to a quarantine device for injecting a chemical liquid into a vehicle passing through, more specifically, to improve the injection of the chemical liquid using a vehicle targeted for quarantine without an electric motor operating with a separate power source, but the passing vehicle is preset. When it exceeds the entry speed, it relates to a non-motorized quarantine device for a vehicle capable of preventing a decrease in the efficiency of injection of a chemical solution according to an entry speed by allowing the chemical solution to be injected through an auxiliary injection part separately installed in the prefabricated body part. To this end, the present invention provides a vehicle non-powered quarantine device: at least a pair of driving panels respectively installed on the floor on which the front and rear wheels of the passing vehicle are to be located, and a plurality of leg panels connected to allow the vehicle to pass between the driving panels. Prefabricated main body portion； A quarantine unit comprising an injection pump for feeding the chemical liquid onto the driving panel and the leg panel, and a plurality of injection pipes connected to the injection pump to inject the chemical liquid into the vehicle； A power unit comprising a safety belt for blocking the driving wheels of the vehicle on one side of the driving panel and inducing stop； And a transmission unit connected to the driving roller to transmit power to the injection pump, and a transmission unit configured to be connected to the gear box to brake the operation of the driving roller. A speed sensor that senses the entry speed of the vehicle； And an auxiliary injection unit installed at a predetermined position of the prefabricated body unit and injecting a chemical liquid when the entry speed of the vehicle exceeds a preset range.본 발명은 통과하는 차량으로 약액을 분사하는 방역장치에 관한 것으로, 보다 구체적으로는 별도의 전원으로 작동하는 전동기가 없이 방역 대상의 차량을 이용하여 약액을 분사할 수 있도록 개선하되 통과 차량이 기설정된 진입 속도를 초과하는 경
