Chain drive mechanism consisting of a) and the rotating shaft 16 of the sprocket wheel 14 and one end of the rotating arm mechanism 8 is fixed to the rotating shaft 16 in a direction perpendicular to the drive of the servomotor 12 The rotating arm mechanism 8 rotates up and down greatly by the rotating shaft which decelerates and rotates about the rotating shaft 16 as a center point.

The rotating arm mechanism (8) is composed of a plurality of shaft members (17), (18), (19) connected in a right angle direction, respectively, and a cylindrical rubber roller (9) is provided at the end of the shaft member. 18 is connected along the shaft member 17 and the rubber roller 9 is movably connected along the shaft member 19 and is moved by loosening and tightening a fastening member such as a conventional fastening means, for example a bolt. It can be fixed at the position, which is to facilitate the adjustment of the position of the rubber roller (9) to the center point of the tailgate (5).

The key release device (2) is a position that is unlocked by measuring the torque when inserted into the key groove of the rotary air cylinder key 20 and the tailgate 5 of the rotary air cylinder key 20 located in the front It consists of a load cell 21 for controlling rotation up to and an air cylinder 22 for advancing or retracting the rotary air cylinder key 20, which is a wheel cylinder, which is operated perpendicular to the movable base member 23. (24) It is installed on the upper side, and the height can be adjusted up and down in accordance with the keyway position of the tailgate (5).

The tailgate opening device 3 has a belt body 28 whose one side is caught by the outer handle 25 of the tailgate 5 and the other side thereof is wound on a rotating shaft 27 which is rotated by the servomotor 26. And a piston of the air cylinder 32 in which the support plate 31 on which the servomotor 26, the sprocket wheel 29, and the chain 30 are mounted is vertically mounted on the base member 23. (32a) It is fixed to the upper portion, but is installed adjacent to the base member 23 and the same as the key release device (2), the belt body 28 is the rotating shaft 27 so that the tail gate 5 is opened only to a certain angle The tailgate 28 is automatically pushed up to the top by the operation of the gas spring 33 provided in the vehicle body, and then fully opened.

Here, reference numeral 34 denotes a belt guide roller, and reference numeral 35 denotes a jack handle for holding a horizontal position of the base member 23.
