装置に関するものである。[Detailed Description of the Invention] In the present invention, since the side fan door is in the same plane as the upper surface of the floorboard, it is possible to open it and discharge the loaded earth and sand far from the side edge of the floorboard. This relates to a door opening/closing device for a dump truck.

などの問題が生じる。Generally, forced VCV times are applied by shilling the side sliding door.
If this silling is to be installed below the floorboard in order to open the silling, the link connecting the silling and the fan door must be complicated to avoid contact with the bent side of the floorboard. Since the ground clearance at the location where this link is installed is also low, problems such as part of the link hitting the tire occur when dumping. In addition, by cutting out a part of the bent side of the floorboard and inserting a link into this notch, the ground clearance at the link installation position can be increased by less than -1.The strength of the side edge of the floorboard will suddenly decrease and the weight of the load will cause Problems arise, such as the side edges of the floorboard becoming more easily damaged.

少くなる。As described above, in the present invention, the link that connects the operating part such as the sill and the sliding door is arranged so as to pass through the notch on the bent side of the floorboard, so the mounting ground clearance of the link is high and the link or the tire will be damaged during side dumping. Since the tubular member was fixed to the notch and the lintel was passed through the tubular member, there was no loss of strength at the end of the floorboard, and since the tubular member protects the link, there was no damage to the link. The degree will also be very low.
