A tank 16 of a sludge suction vehicle 11 is rotatably coupled to a sub-frame 14 on a chassis 13 by hinges 17A and 17B. A pin of the hinges 17A and 17B is a shaft-like body 26 of a pin-type load cell 18. The pin-type load cell 18 is attached such that a direction perpendicular to a thrust force P of dump cylinders 19A and 19B when the tank 16 is caused to incline at a certain angle ¸' is identical with a load detection direction D' .
