The present invention relates to an electric vehicle charger and, more specifically, to an electric vehicle charger including a joint power device for moving a charging gun, which is capable of normally fixing an electric wire pipe without a separate brake device by rotating and fixing the electric wire pipe through a ball screw member. Moreover, in accordance with the present invention, when an external force is exerted to the electric wire pipe, the force exerted to a ball screw nut acts in the same direction as that of a ball screw shaft, however, the electric vehicle charger disables the force from acting in a direction for rotating the ball screw shaft to lead the force to disappear while acting on the ball screw member such that the force is not delivered to a motor or decelerator, and, accordingly, the electric vehicle charger can protect the motor or decelerator without a separate brake device. The electric vehicle charger comprises a charger body, a fixing member, a first joint, a first conduit, a first ball screw member, a second joint, a second conduit, and a second ball screw member.

    본 발명은 전기자동차 충전기에 관한 것으로서, 상세하게는 전선관을 볼 스크류 부재를 이용하여 회전시키고 고정시킴으로써 별도의 브레이크 장치가 없어도 평상시 전선관을 고정할 수 있고, 또한, 본 발명은 전선관에 외부 힘이 가해지는 경우 볼 스크류 너트에 가해진 힘이 볼 스크류 축과 같은 방향으로 작용하게 되지만, 볼 스크류 축을 회전시키는 방향으로는 미작용하도록 해서 그 힘이 볼 스크류 부재에 작용되면서 소멸하게 되어 전동기나 감속기에는 전해지지 않으므로 별도의 브레이크 장치없이도 전동기나 감속기를 보호할 수 있도록 하는 충전 건 이동용 관절동력장치를 구비한 전기자동차 충전기에 관한 것이다.
