してなるダンプカー荷台のシート掛け装置。 A drive shaft is rotatably mounted inside the casing constituting the main body of the device along its length, both ends of which are supported by suitable support mechanisms, and which has a screw carved into its outer periphery. The shaft is configured to transmit the rotational force of the motor through a speed reduction mechanism such as a gear attached to one end, and the drive shaft is provided with screws corresponding to forward or reverse rotation of the drive shaft. A movable body that moves in either the left or right direction according to the situation is slidably attached, and a driving link, a connecting link, and a crank arm are sequentially installed between the upper end of the movable body and the rotation axis of the seat. The above-mentioned links, etc., extend and contract or rotate in parallel with the rotation of the drive shaft as the movable body slides in response to the rotation of the drive shaft. The rotating shaft of the seat is configured to rotate, and the distal end of the movable body is pivotally connected to the base end of the drive link, and the base end of the link located at the other end The part is attached to the rotating shaft of the seat and serves as a crank arm for rotating the rotating shaft of the seat, and there is a fixed crank arm between the tip of the crank arm and the drive link connected to the tip of the drive shaft. Connecting links that rotate and slide while following the sliding locus and rotation locus of the three links are connected, and the three links operate so as to be pulled or pushed apart in the sliding direction according to the movement of the moving body. A sheet hanging device for a dump truck loading platform configured as follows.
