摘要： PURPOSE: To provide a lock device which has a simple structure and is very convenient by providing a disc having a projection, a disc having an oblong hole, etc., in an opening and closing device of a door of a work vehicle so that the door can be opened from the inside of the vehicle even if it is locked from the outside thereof. CONSTITUTION: An opening and closing operation device 30 of a door of a work vehicle such as a crawler type running cart, etc., is provided with a disc having a circular arc oblong hole 33d (transmission member) 33 and a disc provided with an interlocking pin 34b which engages with the oblong hole 33d (transmission member) 34, and the disc 33 is connected to an outside handle 32 and the disc 34 is connected to an inside handle 36. When the door is locked from the outside of the vehicle, the disc 33 is fixed, and the handle 32 cannot be operated. Even in this condition, the interlocking pin 34b slides in the oblong hole 33d by turning the inside handle 36 so that the door can be opened from the inside of the vehicle while it is locked. Still, it is impossible to open the door from the outside thereof if the door is closed. Consequently, it is possible for a driver to go to an engine room directly from a driver's seat.

摘要： PROBLEM TO BE SOLVED: To prevent an operating lever from abutting an operator's seat even in the case of tilting up an operator's cabin. SOLUTION: A working vehicle has a turning table 11 provided in a turnable state on a travel device; an operator's cabin 15 provided in an upward tiltable state on the turning table 11; an operating lever 19 provided in the operator's cabin so as to be swingingly operated in the same direction as a tilt-up direction and operated by a worker; and a link 49 for connecting the base part of the operating lever 19 to a control valve 57 provided at the turning table 11 so as to transmit the operation of the operating lever 19 to the control valve 57. The tilt-up rocking center of the operator's cabin 15 is coaxial with a pivotal connection part 49d of the link 49 to be the rocking center of the operating lever 19. When the operator's cabin 15 is tilted up, an operator's seat 17 in the operator's cabin 15 is tilted up, and the operating lever 19 is tilted up in the connected state to the control valve 57 without abutting the operator's seat 17.
