PROBLEM TO BE SOLVED: To make a soft arrow sign simple to handle and foldable to a small size by utilizing the magnetic force of rubber plastic as a mounting system and make the soft arrow sign foldable in order to allow carrying and to minimize a space for housing. SOLUTION: A rear plastic sheet 18 on which pockets 15, into the lower part and upper part of which rubber magnets 19 are housed, a box 16 into which a dry cell is housed and a switch 17 are arranged, is formed. After the rubber magnets 19 are inserted into the pockets 15, their insertion parts are fused and hermetically sealed. The sheet is recommended to be provided with fixing bands for convenience of securely fixing the sheet when the sheet is folded and housed. As a result, the arrow mark which does not occupy space for housing and is convenient to carry is obtained. Also, an arrow display is formed by subjecting the front surface of a white prism lens type retroreflection sheet to reverse screen printing with transparent red ink. Further, the rear surface of the retroreflection sheet is printed with transparent ink in order to smooth the prism of the rear surface, to form a belt-like arrow display on the rear surface. As a result, the visibility is improved.
