ROAD SURFACE CLEANING DEVICE
To provide a method by which falling of abrasives from a road surface is prevented.SOLUTION: A road surface cleaning device comprises an abrading unit 30 and an abrading unit receiver 40 to which the abrading unit 30 is detachably attached. The receiver 40 comprises a projecting cylinder part 170 inserted into an opening part 135 of a fixture 32 of the abrading unit 30, an opening and closing member 180, and a regulation member 190 regulating a movement of the opening and closing member 180 toward a closing direction. The opening and closing member 180 comprises a pair of engagement parts 182 that project from a pair of opening parts 174 of the projecting cylinder part 170 and are engageable with stopper parts 134 and an energizing member 181 energizing a pair of the engagement parts 182 to open the opening and closing member 180. When the opening and closing member 180 is in an open state, the projecting cylinder part 170 is inhibited to withdraw from the opening part 135 by engaging action of a pair of the engagement parts 182 with the stopper parts 134 and when the opening and closing part 180 is in a closed state, the projecting cylinder part 170 is allowed to withdraw from the opening part 135 of the fixture 32.SELECTED DRAWING: Figure 6
【課題】研摩子の脱落を防止する。【解決手段】踏面清掃装置は、研摩子３０と、研摩子３０が着脱自在に取り付けられる研摩子受け４０とを備え、研摩子受け４０は、研摩子３０の取付具３２の開口部１３５に挿入される突出筒部１７０と、開閉部材１８０と、開閉部材１８０の閉方向への動作を規制する規制部材１９０と、を有し、開閉部材１８０は、突出筒部１７０の一対の開口部１７４から突出し、ストッパ部１３４に係合可能な一対の係合部１８２と、開閉部材１８０が開かれるように、一対の係合部１８２を付勢する付勢部材１８１と、有し、開閉部材１８０が開状態のときには、一対の係合部１８２がストッパ部１３４に係合することにより、突出筒部１７０が開口部１３５から抜け出ることが禁止され、開閉部材１８０が閉状態のときには、突出筒部１７０が取付具３２の開口部１３５から抜け出ることが許容される。【選択図】図６
