CABIN INSTALLATION STRUCTURE FOR VEHICLES

To provide a cabin installation structure for vehicles making it possible to readily fit a bolt and reduce the number of components.SOLUTION: A substantially cylindrical collar member 35 is coaxially fixed to the top of a cabin side bolt hole 32 penetrating through a cabin side mount bracket 25 and mount retainer 27. The collar member 35 has a ring-shaped flange 35A, which is fixed to the top surface of the mount retainer 27 through welding, at one end, and has a groove 35C, which is formed in a radial direction, at the other end opposite in an axial direction to the one end. A bolt 31 has a head 31A that is abutted against the other end of the collar member 35 from above when the bolt is inserted into the cabin side bolt hole 32 from above the collar member 35, and a convex part 31D that juts downwards in the axial direction from the underside of the head 31A in the radial direction, and is fitted into the groove 35C. The bolt 31 is inserted into the collar member 35 from above, and the convex part 31D is fitted into the groove 35C.SELECTED DRAWING: Figure 1 【課題】ボルト装着を容易に行うことができると共に、部品点数を削減できる車両用キャビン取付構造を提供する。【解決手段】キャビン側マウントブラケット２５及びマウントリテーナ２７を貫通するキャビン側ボルト孔３２の上側に同軸に固着される略円筒状のカラー部材３５を有し、カラー部材３５は、一端部にマウントリテーナ２７の上側面に溶接によって固着されるリング状のフランジ部３５Ａと、一端部に対して軸方向反対側の他端部に径方向に沿って形成された溝部３５Ｃと、を有し、ボルト３１は、カラー部材３５に上側から挿通されてキャビン側ボルト孔３２に挿通された場合に、カラー部材３５の他端部に上側から当接される頭部３１Ａと、頭部３１Ａの下面から半径方向に沿って軸方向下側に突出し、溝部３５Ｃに嵌入される凸部３１Ｄと、を有し、ボルト３１がカラー部材３５に上側から挿通されて、凸部３１Ｄが溝部３５Ｃに嵌入されるように構成する。【選択図】図１
