PURPOSE:To slide an assistant driver's seat to a position near the front end of a cabin without any interference with an operating lever and use the seat as a bed or the like, by providing an operating lever at a front part of the assistant driver's seat in a stretchable manner. CONSTITUTION:Where the assistant driver's seat is in the erected position, the operating lever 11 is in the stretched position so that a hydraulic pressure change-over valve or the like can be operated through an arm and a transmitting member 9 by operating the lever 11. When using the assistant driver's seat as bed or the like, the lever 11 is depressed downward to release the connection between a circumferential groove 12 and a notched ball 13, and the lever 11 is depressed by sliding into a cylindrical body 8. Thereafter, the assistant driver's seat is slidden. |
