Provided is a spray pipe angle control member of a disinfection device installed in a two-wheeled vehicle, which enables a spray angle of a chemical compound to be adjusted during the disinfection process by rotatably fixating a spray means constituting the disinfection device to a carrier member of a two-wheeled vehicle. To realize this, the spray pipe angle control member of the disinfection device installed in a two-wheeled vehicle allows a spray means, comprising a chemical tank and a spray pipe which is installed in the chemical tank and sprays the chemical compound, to be rotatably supported by a carrier member installed in the rear side of a two-wheeled vehicle. A technical base of the present invention is to comprise: a fixed frame which is fixated to the carrier member and in which long front and rear guide holes are respectively penetrated through front and rear sides of the upper surface thereof； a rotational frame which is coupled on the fixed frame by a hinge pin and adjusts a spray angle of the chemical compound injected from the spray pipe by rotating around the hinge pin while supporting the chemical tank； front and rear guide pins which protrude from front and rear sides of the bottom surface of the rotational frame and guide a rotation of the rotational frame by moving along the long front and rear guide holes in accordance with the rotation of the rotational frame while being respectively inserted into the long front and rear guide holes； and a stopper which is installed on the rear side of the rotational frame and the fixed frame, and maintains the spray angle of the spray means in the adjusted state by selectively constraining the rotation of the rotational frame.본 발명은 방역장치를 구성하는 분무수단을 이륜차의 짐받이부재에 회전 가능하게 고정시켜 방역 작업과정에서 약제의 분무각도를 조절할 수 있도록 한 이륜차에 설치되는 방역장치의 분무파이프 각도 조절부재를 제공한다.이를 구현하기 위한 본 발명은 약제탱크와, 상기 약제탱크에 설치되며 약제를 분무하는 분무파이프로 구성하는 분무수단을 이륜차의 후방에 설치되어 있는 짐받침부재에 회전 가능하게 지지시키는 이륜차에 설치되는 방역장치의 분무파이프 각도 조절부재에 있어서, 상기 짐받침부재에 고정되며 상면 전, 후방에는 전, 후
