PROBLEM TO BE SOLVED: To beautifully draw a straight line or circular line without being affected by hand movement by easily carrying a liner body of a liner to draw a white line on a ground for preparation before sports. SOLUTION: The distal ends of two frames 12 and 12 of the same length are fixed to the lower part of both side surfaces 16, 17 or a rear surface 19 of the liner body, and distal ends of two frames 22 and 22 of the same length are connected to the rear ends of the frames 12 and 12 in such a way as can be bent. A flat plate 3 is horizontally bridged between the rear ends of the frames 22 and 22, and a shaft 6 erected at the center of a rotating plate 4 is rotatably journaled to a hole 7 bored at the center on the flat plate 3 in the longitudinal direction. Wheels 1 and 1 are rotatably journaled to both ends of an axle 8 attached to the rotating plate 4, and a stopper 10 is disposed for fixing the angle of the axle 8 or 18 in the traveling direction at a desired position.
