PURPOSE: To provide durable projections for introducing a visual handicapped person in a short time by running a running device along a line of previously laid resin material, and intermittently letting flow out projection forming resin material at regular intervals. CONSTITUTION: A receiving tank 2 for projection forming resin material W is loaded on a running device having front and rear wheels, a frame body 3 having an outflow port 30 opening downward is provided on the bottom part of the tank 2, and a first opening/closing body 31 opening/closing the outflow port 30 is supported slidably in the longitudinal direction. A plurality of grounding bodies 4 extending in the longitudinal direction are arranged on the underside of the first body 31 spacedly by a fixed space S, and a projection forming outflow port 5 having outflow ports 50 opening rearward in the advancing direction between the adjoining grounding bodies 4 is provided. A line L is previously laid on the road surface R with a line forming material, after hardening, the running device is run along the line L, the outflow ports 50 are intermittently opened/closed at regular intervals based on the rotating speed of the wheels, and the material W is intermittently let flow from the outflow port 5 so as to form the projections for introducing a visual handicapped person. |
