To provide a road surface cleaning vehicle which can simplify the structure relating to opening and closing of a discharge door of a hopper having a latch, resulting in reduction in cost.SOLUTION: There is provided a road surface cleaning vehicle configured such that: under a situation where an operation end is located at a second engagement position in the state where a discharge outlet is closed by a discharge door 10, when a hydraulic cylinder 15 is caused to perform contraction operation while latches 26, 26 are located at a lock position, the operation end moves to a first engagement position so that the latches 26, 26 move to an unlock position by means of a linkage mechanism 25 and the contraction operation of the hydraulic cylinder 15 from the first engagement position causes the discharge door 10 to perform opening operation; and under a situation where the operation end is located at the first engagement position in the state where the discharge outlet is opened by the discharge door 10, when the hydraulic cylinder 15 is operated to be extended while the latches 26, 26 are located at the unlock position, the operation end operates to close the discharge door 10 and then moves to the second engagement position against energization of discharge coil springs 22, 22, so that the latches 26, 26 move to the lock position by means of the linkage mechanism 25.SELECTED DRAWING: Figure 4
【課題】ラッチを有するホッパの排出ドアの開閉に係る構造を簡略化でき、低コストとなる路面清掃車を提供する。【解決手段】路面清掃車において、排出ドア１０による排出口の閉状態で、動作端が第２の係止位置にあり、ラッチ２６，２６がロック位置にある状態から油圧シリンダ１５を収縮動作させると、動作端が第１の係止位置に移動することで、ラッチ２６，２６は連係機構２５を介してロック解除位置に移動し、第１の係止位置からの油圧シリンダ１５の収縮動作で排出ドア１０が開動作する一方、排出ドア１０による排出口の開状態で、動作端が第１の係止位置にあり、ラッチ２６，２６がロック解除位置にある状態から油圧シリンダ１５を伸長動作させると、動作端が排出ドア１０を閉動作させた後、コイルバネ２２，２２の付勢に抗して第２の係止位置に移動することで、ラッチ２６，２６は連係機構２５を介してロック位置に移動する。【選択図】図４
