The backrest (4) which doubles as the above is provided so as to be located above the control handle (9). (12) is a seat which is fixed to both sides of the rear part of the lateral frame of the frame (5) by facing the rear part of the seat mount (2), and (13) and (14) are the rear face of the seat mount (2) and the frame. The ends of the wire (7) of the supporting member are fixed to them by the clasps respectively fixed to the rear portions of the horizontal frames of (5). (15) is an elastic receiving member that is fitted and placed on the steering handle (9).

Next, the operation will be described. When driving the mobile device (A), the driver sits on the seat panel (3) and steers the mobile device (A) in a forward-facing state in which the seat (a) is laid down as shown in FIG.

On the other hand, when operating a rear working machine (not shown) such as a backhoe, a crane, and a winch attached to the rear of the vehicle body (1) to work, the seat (a) is moved from the above state to the shaft rod (6). If the seat back (4) is rotated forward as a fulcrum, as shown in FIG. 2, the backrest (4) with the rearward facing auxiliary seat (10) of the seat (a) reaches above the steering wheel (9) and the seat (a) is reached. Stands up to a rearward facing seat, and the wire (7) is tensioned so that the seat (a) is supported by the wire (7) in the standing position. Therefore, thereafter, the operator sits backward on the rearward-facing auxiliary seater (10) of the backrest (4) that also serves as the rearward-facing auxiliary seater of the seat (a), and faces the rear working machine to face the rear working machine. To drive.
