PURPOSE:To construct an automatic open/close unit for rear swing door with simple link mechanism by coupling a fixed arm integral with a rear swing door through a rod with an operating arm journaled to the underface of rear body while contacting a roller journaled to the chassis against the guide face at the lower end of operating arm. CONSTITUTION:Upon tilting of rear body mounted on the chassis 1 rearward around the rear hinged section 3, an operating arm 14 journaled 15 to the underface at the rear of the rear body 2 will roll forward while being guided through a roller 17 journaled to the sideface of the chassis frame 1. Consequently, the rear swing door 9 journaled to the rear end of the floor face 10 of the rear body 2 will move rearward through a rod 16 to contact against a limiting member 8 at the rear end of extension frame 5 to be flush with the floor face 10 4thus to form an extended shoot. Upon further tilting of the rear body 2, the operating arm 14 will be separated from the roller 17 to tilt the floor face 10 and the rear swing door 9 while maintaining flushness thus to discharge the material mounted on the rear body 1 to remote position. |
