To provide an automatic gate opening/closing driving gear which can be easily mounted onto the lower side of a rear deck of a truck by narrowing the width in the vertical direction of a movable region of a link mechanism which rotationally driving a gate, improves structural strength and can improve the reliability and permits a long life of a device.SOLUTION: An automatic gate opening/closing driving gear includes a frame 16 fastened to a stand frame F, a driving arm 22 of which one end is freely rotatably attached to a lower part of an outer surface of a gate H and the other end is extended out to the lower side of the frame, an electric cylinder 18 which is attached to the frame and is provided with a cylinder rod 20 freely movably forward/backward, a first link mechanism 12 which is attached to the frame and is wholly oscillated and driven by forward and backward movement of the cylinder rod and a second link mechanism 14 which is attached to the frame, connects the other end of the driving arm and the first link mechanism and, at the same time, moves the other end of the driving arm between an extruding position and a pulling-in position along substantially horizontal direction in accordance with the oscillation of the first link mechanism.SELECTED DRAWING: Figure 2
【課題】アオリを回動駆動するリンク機構の可動領域の上下方向の幅を狭くし、トラックの荷台の下方への装着を容易にし、構造強度をより向上させ、装置の信頼性の向上と長寿命化を図ることのできる自動アオリ開閉駆動装置を提供する。【解決手段】台枠Fに固定されたフレーム16と、一端がアオリHの外面の下部に回転自在に取り付けられ、他端がフレームの下方まで延出した駆動アーム22と、フレームに取り付けられ、シリンダロッド20を進退自在に備えた電動シリンダ18と、フレームに取り付けられ、このシリンダロッドの進退移動により全体的に揺動駆動される第1のリンク機構12と、フレームに取り付けられ、駆動アームの他端と第1のリンク機構とを連結すると共に、第1のリンク機構の揺動に応じて、駆動アームの他端を、押し出し位置と引き込み位置との間で、略水平方向に沿って移動させる第2のリンク機構14とを備える。【選択図】図2
