Problem to be solved: a linear projection for guiding a person with visual impairment has a feeling that the user is thin even if it is made by a white stick, and the user has a fear that the user does not have confidence to know the longitudinal direction and is not confident. In addition, it is not stable for a white stick with a stick with a different thickness.A projection 4 for forming a corner 4C extending from the upper surface 4a to the left and right side surfaces 4b is provided on the surface of the linear projection 3 for guiding a visually handicapped person.Diagram【課題】視覚障害者誘導用の線状突起は、白杖の使用者によって、白杖でなでられても使用者の感触が薄く、使用者が、長手方向を知るには、時間がかかるとともに、確信を持てない不安がある。さらに、太さの違う杖先を付けた白杖では当たりが安定しない。【解決手段】視覚障害者誘導用の線状突起３の表面に、上面４ａから左右の側面４ｂにかけての角４ｃを形成する突起４が設けられている。【選択図】図１
