PURPOSE: A road marking device is provided to improve marking speed by arranging multiple nozzles in a row, and to mark various patterns by additionally forming an oblique nozzle and a circular nozzle. CONSTITUTION: A road marking device(100) comprises a support frame(110), a spray module(130), and a X-axis transfer unit(140). The support frame is formed in a square shape in order to protect from external impact. The spray module is formed in the inner side of the support frame. Multiple spray nozzles(N1~N18), which have the same shapes, are arranged in uniform intervals in the spray module. The X-axis transfer unit transfers the spray module in an X-axis direction. |
