To improve workability.SOLUTION: A cab support structure includes a mount device installed on a vehicle body frame and a connection mechanism which connects a cab installed above the vehicle body frame with the vehicle body frame through the mount device rotatably between a seating position and a tilt position. The connection mechanism includes: a connection shaft connected with the mount device and extending in the horizontal direction; a displacement allowance member connected with the vehicle body frame; and an interlock member connected with the cab and rotatable by interlocking with the rotation of the cab. The displacement allowance member includes a displacement allowance hole which allows a displacement of the connection shaft in the vertical direction and allows the rotation of the connection shaft between the seating position and the tilt position. The interlock member includes a displacement allowance section which allows the displacement of the connection shaft in the vertical direction at the seating position and a displacement regulation section which regulates the displacement of the connection shaft in the downward direction at the tilt position.SELECTED DRAWING: Figure 4

    【課題】作業性を向上する。【解決手段】キャブ支持構造は、車体フレームに設けられたマウント装置と、前記マウント装置を介して前記車体フレームの上方に設けられたキャブを着座位置とチルト位置との間で回動可能に前記車体フレームに対して連結する連結機構と、を備え、前記連結機構は、前記マウント装置に連結され、水平方向に延びる連結軸と、前記車体フレームに連結された変位許容部材と、前記キャブに連結され、前記キャブの回動に連動して回動可能な連動部材と、を備え、前記変位許容部材は、前記連結軸の上下方向への変位を許容するとともに、前記着座位置と前記チルト位置との間において前記連結軸の回動を許容する変位許容孔を有し、前記連動部材は、前記着座位置のときには前記連結軸の上下方向への変位を許容する変位許容部と、前記チルト位置のときには前記連結軸の下方への変位を規制する変位規制部と、を有する。【選択図】図4
