PROBLEM TO BE SOLVED: To provide good seat feeling in both forward work and backward work and to easily provide an optimal maneuvering attitude in both works. SOLUTION: A turning support device comprises a support block 50 of which front end is journalled to a car body vertically oscillatably and back end is supported elastically via a cushion member 57, a rotating block 52 for supporting a driver seat 21 rotatably around a vertical shaft, a link mechanism 51 that connects the rotating block 52 to the support block 50 movably to a front lower position A and a back upper position, sets the driver seat 21 at a forward tilting attitude when the rotating block 52 is moved to the front lower position A, and sets the driver seat 21 at a backward tilting attitude when the rotating block 52 is moved to the back upper position, and a fixing means 59 that fixes the driver seat 21 to the support block 50 when the rotating block 52 is moved to the front lower position A and the driver seat 21 is tilted forward and fixes the rotating block 52 to the car body side when the rotating block 52 is moved to the back upper position and the driver seat 21 is tilted backward. |
