PROBLEM TO BE SOLVED: To restrain the vibration transmission in a high frequency area to a cab deck from an engine deck from largely increasing, by restraining vibration in a low frequency area of the cab deck, with a simple constitution.SOLUTION: A cab deck 30 is fixed to a turning frame 10, and is arranged on the front side Y1 more than the engine deck 20 by opening a clearance S between the engine deck 20 and itself. A plate-like member 40 connects the engine deck 20 and the cab deck 30. The thickness direction of the plate-like member 40 is the vertical direction Z. A cab side fixing position 43 of the plate-like member 40 is arranged on the front side Y1 more than a rear end part 31r of the cab deck 30.SELECTED DRAWING: Figure 2

    【課題】簡易な構成で、キャブデッキの低周波数域での振動を抑制し、エンジンデッキからキャブデッキへの高周波数域での振動伝達が大幅に増加することを抑制する。【解決手段】キャブデッキ30は、旋回フレーム10に固定され、エンジンデッキ20との間に隙間Sをあけてエンジンデッキ20よりも前側Y1に配置される。板状部材40は、エンジンデッキ20とキャブデッキ30とを接続する。板状部材40の厚さ方向は、上下方向Zである。板状部材40のキャブ側固定位置43は、キャブデッキ30の後端部31rよりも前側Y1に配置される。【選択図】図2
