PURPOSE:To make it possible to tilt a cab by only an operation of the switching lever of a hydraulic pump by interlocking a starting switch of an electric motor with a switching operation lever of the hydraulic pump. CONSTITUTION:A cab 2 is adapted to be tilted by a hydraulic cylinder 4 which is adapted to be actuated by pressure oil from a hydraulic pump 3. Said hydraulic pump 3 is adapted to be driven by an electric motor 7, and a relay 11 is connected in series between a driving circuit of the electric motor 7 and a power source 12 via a fusible link 13 and a switch 15 is connected in series to an excitation coil 11a of the relay 11. The switch 15 is arranged to interlock with a switching operation lever 6 so that the hydraulic pump can be actuated only by operating the operating lever 6 to the tilt side or the non-tilt side. |
