PROBLEM TO BE SOLVED: To reduce vibrations of a cab panel while suppressing an increase in a number of components.SOLUTION: A bracket 11 formed to have a hat-shaped cross section is provided, and a flange portion 11a of the bracket 11 is fixed to a roof panel 2a. A rubber member 12 is disposed across a web portion 11b of the bracket 11, and a room lamp 13 is suspended from the web portion 11b through the rubber member 12. A spring-mass system is composed of the rubber member 12 and the room lamp 13, and functions as a dynamic damper for reducing vibrations of the roof panel 2a.SELECTED DRAWING: Figure 1

    【課題】部品点数の増加を抑制しながら、キャブパネルの振動を低減することができるようにする。【解決手段】断面ハット型に形成されたブラケット11を設け、ブラケット11のフランジ部11aをルーフパネル2aに固定する。また、ブラケット11のウェブ部11bを挟んでラバー部材12を配置し、かつラバー部材12を介してウェブ部11bにルームランプ13を吊り下げる。ラバー部材12とルームランプ13とでバネ—マス系を構成し、ルーフパネル2aの振動を低減するダイナミックダンパとして機能させる。【選択図】図1
