HIGH ROOF STRUCTURE OF TRUCK

To improve support rigidity of a frame.SOLUTION: In a high roof structure of a truck in which a high roof type roof panel is attached to the upper side of a cab body, the roof panel includes: a body forming a ceiling part; and side surface parts each having a corner part which is formed curved from the body in lateral and downward directions and is supported from the inner side in a passenger compartment by a roof frame. The roof frame includes: a main frame 3 including width direction parts 31 formed along the body, and vertical direction parts 35 each having a curved part 33 which is formed curved from the width direction part in the lateral and downward directions and has a curvature smaller than that of the corner part to be separated from the corner part, the main frame 3 attached at lower ends of the vertical direction parts to the cab body; and sub frames 4 each of which is disposed between the main frame 3 and the roof panel and extends curved from a connection part between the body and the side surface part in the lateral and downward directions. The sub frame 4 includes a curved part 41 formed along a shape of the corner part. Further, one end of the sub frame 4 is joined to the main frame 3 near the connection part and the other end is attached to the cab body 5.SELECTED DRAWING: Figure 1 【課題】フレームの支持剛性を向上させる。【解決手段】キャブ本体の上方にハイルーフ型のルーフパネルが取り付けられたトラックのハイルーフ構造であって、ルーフパネルは、天井部をなす本体部と、本体部から側方下向きに湾曲形成されたコーナー部を有する側面部とを備え、ルーフフレームにより車室内側から支持され、ルーフフレームは、本体部に沿った幅方向部３１と、幅方向部から側方下向きにコーナー部よりも小曲率でコーナー部から離隔した湾曲部３３を有する上下方向部３５とを備え、上下方向部の下端部がキャブ本体に取り付けられるメインフレーム３と、メインフレーム３とルーフパネルとの間に配置され、本体部と側面部との連結部近傍から側方下向きに湾曲して延びるサブフレーム４と、を有し、サブフレーム４は、コーナー部の形状に沿った湾曲部４１を備え、一端部が連結部近傍でメインフレーム３と接合され、他端部がキャブ本体５に取り付けられる。【選択図】図１
