PROBLEM TO BE SOLVED: To enable smooth locking/unlocking and to improve operability and safety by releasing locking of a control handle by a locking mechanism and returning the control handle to its original position when a moving member is moved from an unlocking position to a locking position side by a releasing mechanism. SOLUTION: When a control handle 28 is pulled from locking states of cab lock devices 14a, 14b, rotating levers 24a, 24b are rotated by an operating piece 29. Poles 18a, 18b are rotated, locking of strikers 12a, 12b by latches 16a, 16b is released, the cab lock devices 14a, 14b become unlocking states and a cab 13 can be tilted. When the rotating levers 24a, 24b are rotated up to unlocking positions by the operating lever 29 of the control handle 28, first hooks 36a, 36b of locking levers 34a, 34b lock locking parts 30a, 30b, second hooks 37a, 37b lock the operating piece 29 and the control handle 28 is locked at an operation position. |
