PURPOSE:To prevent a car body from damages and improve the efficiency of operation by connecting vertically pivotably a rotary arm to the upper edge of a rear body side plate to slidably insert a support arm pivotably connected to a rear door into said rotary arm. CONSTITUTION:A bottom plate 3 having a rotary arm 4 pivotably connected is secured fixedly to the upper edge 5 of a rear body side plate. A support arm 2 is slidably inserted in the rotary arm 4 and mounted on a rear door 1. When a rear body 23 begins to ascend, a catch 19 is released and a load 18 descends to bear against the rear door 1. The rear door 1 pivots about a door rotating rotary shaft 13 in the direction of arrow 20 and the more the descending force of the load 18 is, the more the support arm 2 pivots about the rotary shaft 11 in the direction of arrow 21. The turning of the support arm 2 is transmitted to the rotary arm 4 which is turn pivots about the rotary shaft 8 in the direction of arrow 22. Thus, impact of descending load is absorbed, while a descending port of the load is largely opened. |
