PROBLEM TO BE SOLVED: To form an alert-groove on a road surface which notifies a driver or the like of lane deviation by a large sound and vibration by making an attention groove forming device merely advance straight once in one direction.SOLUTION: A front face 21 being a front end and a rear face 22 being a rear end are arranged in a vertical direction, a front inclined face 23 is extended up to the lowest side 231 which forms the lowest part 23a toward an obliquely-downward rear side from a lower side 211 of the front face 21, a rear inclined face 24 extending to an obliquely-upper rear side from the lowest side 231 is joined to the lower side 221 of the rear face 22 at a position which is higher than the lower side 211 of the front face 21 in a vertical direction, and alert groove forming attachments 2 having shapes in which linear distances from the front face 21 of the lowest part 23a are about one fifth with respect to linear distances from the rear face 22 to the front face 21 are detachably attached to an alert-groove forming device 1 at a prescribed interval W in one direction D1 at an interval from one end 121 of a peripheral face of a rear wheel 12 in a width direction, and also at a prescribed interval W in the other direction D2 at an interval from the other end 122 of the peripheral face of the rear wheel 12 in the width direction, thus constituting the alert-groove forming device.SELECTED DRAWING: Figure 1
【課題】一方向に一度直進するだけで、大きな音と振動で車線逸脱を運転手等に知らせる注意喚起溝を路面に形成する。【解決手段】前端となる前面２１及び後端となる後面２２が鉛直方向に設けられ、前面２１の下辺２１１から斜め下の後方へ最下部２３ａを形成する最下辺２３１まで前方傾斜面２３が延び、最下辺２３１から斜め上の後方へ延びる後方傾斜面２４が、前面２１の下辺２１１よりも鉛直方向に高い位置で後面２２の下辺２２１と接合し、前面２１から後面２２までの直線距離に対する最下部２３ａの前面２１からの直線距離が約５分の１である形状の注意喚起溝形成用アタッチメント２を、後輪１２の周面の幅方向一端１２１から間隔をあけて一の向きＤ１に所定間隔Ｗで、後輪１２の周面の幅方向他端１２２から間隔をあけて他の向きＤ２に所定間隔Ｗでそれぞれ着脱可能に取り付け、注意喚起溝形成装置１を構成する。【選択図】図１
