MARKING TOOL
To solve the problem in conventional marking tools having a plano-convex lens function that use acrylic resin or the like as a material for the plano-convex lens in which the translucency deteriorates such as white turbidity due to ultraviolet rays and the like when used for a long period of time.SOLUTION: In order to solve problems such as translucency deterioration in addition to providing durability and weather resistance as a marking tool installed on roads, etc., a marking tool, being a luminous marking tool that is also resistant to deterioration due to ultraviolet rays, that avoids peeling of an attachment between a plano-convex lens and a base forming the base plate thereof is provided.SELECTED DRAWING: Figure 1
【課題】平凸レンズ機能を有する標示具において、従来は平凸レンズの素材としてアクリル樹脂などを用いていた。そのため、長時間使用すると紫外線などによる白濁などの透光性の劣化を来たす、という課題があった。【解決手段】上記課題を解決するために、道路等に設置される標示具としての耐久性や耐候性に加えて、紫外線による劣化にも耐性のある夜光の標示具であり、平凸レンズとその基盤をなすベースとの貼着の剥離を回避する標示具を提供する。【選択図】図１
