To secure a wide opening area which discharges a load when a loading platform is inclined backward with such a simple structure as to prevent an increase in the number of components irrespective of the loading platform having an inclined rear end face shape.SOLUTION: In a tail gate mechanism A of a trailer T, a rear end face shape of a loading platform 3 installed so as to be tiltable to a chassis frame 1 is formed into a shape due to an inclined rear end face 3d becoming a rear end face position on the rear part of the vehicle toward the loading platform bottom surface side from the upper end of the loading platform. A tail gate 4 contacts and closes the inclined rear end face 3d when the loading platform 3 is in a horizontal state, and suspends and supports so as to be rotatable to the loading platform 3 by a hinge pin 5 so that the gate lower end face is opened downward according to a loading platform inclination angle θc when the loading platform 3 is inclined backward. A position of a hinge pin 5 mounted so as to penetrate through the loading platform side supporting bracket 8 and the gate side support bracket 9 is set at a position that is offset to the rear side of the rear upper end angle position P of the loading platform 3 and at a position that is offset to the upper side of an upper end face U of the loading platform 3.SELECTED DRAWING: Figure 2

    【課題】荷台が傾斜後端面形状であるにもかかわらず、部品点数を増大させない簡単な構成によって荷台の後方傾動時に積荷を排出する広い開口面積を確保すること。【解決手段】トレーラTのテールゲート機構Aにおいて、シャシフレーム1に対して傾動可能に設置した荷台3の後端面形状を、荷台上端から荷台底面側に向かうほど車両後方の後端面位置になる傾斜後端面3dによる形状にする。テールゲート4は、荷台3が水平状態であるときに傾斜後端面3dに接触閉鎖し、荷台3が後方傾動するときに荷台傾斜角度θcに応じてゲート下端面が下開きするように荷台3に対してヒンジピン5により回動可能に吊り下げ支持する。荷台側支持ブラケット8とゲート側支持ブラケット9とを貫通して取り付けられたヒンジピン5の位置を、荷台3の後方上端角位置Pより後方側へオフセットさせた位置であって、かつ、荷台3の上端面Uより上方側へオフセットさせた位置に設定する。【選択図】図2
