で、以下実施例を図面にて説明する。 The conventional canopy opening/closing device was already put into operation in 168416.
As shown in Fig. 1, a lift arm 02 and a swing arm 03 are rotatably supported on a cargo box 01,
A seat frame 05 for attaching a seat 04 is pivotally supported at the tips of the seats 2 and 03, and by rotating the lift arm 02, the seat frame 05 is moved from the solid line position to the dashed-dotted line position to move the upper part of the cargo box 01. It's starting to open up. However, if the device described above is used in a cargo box that can be discharged from the side,
When the seat frame is in the dash-dotted line position, the center of rotation of the lift arm and the pivot point between the swing arm and the seat frame are separated, so the lift arm and the seat frame become rigid bodies, and the side fan door opens. It has the disadvantage that it cannot be opened because it is obstructed by the lift arm and seat frame. The present invention eliminates the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.
