る。[Prior Art] In a road cleaning vehicle, for example, a vacuum type road cleaning vehicle, the suction performance (air volume,
Negative pressure) is maintained at a predetermined value, and in order to increase work efficiency, it is possible to run slowly when there is a large amount of dirt, etc. on the road surface, and faster when the amount of dirt, etc. is small, and for non-work such as forwarding. When driving, it is required to be able to achieve speeds comparable to those of ordinary trucks.
上記要求を満足するため、従来の路面清掃車
