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
