PURPOSE:To obtain a cab lock device having simple construction, a few number of parts, and high accuracy, by providing lock pins arranged on either of a tilt cab side or a chassis side, hooks engaged with the pins, springs hung between supporting pins of hooks and connecting pins, and the like. CONSTITUTION:In the condition in which a cab is locked on the chassis side, a hook 12 is inclined left until a stopper pin 14 is contacted with a stopper for normal times, and because it is engaged with a supporting pin 16 at the bottom of the short hole 12d of a dog-legged hole 12b, the hook part 12a is strongly engaged with a lock pin 11, and in addition a coil spring 18 assists the engagement. For releasing the locking in this condition, the hook 12 is rotationally moved around the lock pin 11 as a supporting point through the connecting pin 13, after the supporting pin 16 is positioned on the boundary of long and short holes 12c, 12d of the dog-legged hole 12b, the pin is positioned on the lower end of the long hole 12c. Further, the hook 12 is rotationally moved centering around the supporting pin 16, and the hook part 12a is gradually separated from the lock pin 11. |
