PURPOSE:To raise the operability of a working vehicle by providing a switching operation mechanism by which the interlocking action of a back hoe device and a turn table by an interlocking mechanism is released and the table is fixed on a position where a boarding and operating section is turned forward in relation to a slewing base. CONSTITUTION:A rocking coupler 16 is connected with the coupling groove 18 of an outer ring part 13, and the outer ring part 13 and a central ring member 11 are turned integrally to an inner ring member 10. A turn table 7 is turned synchronously with the bilateral rocking of a back hoe device 4, and a boarding operation section 3 is altered toward the same direction as the rocking direction of the back hoe device 4. The coupler 16 is also coupled with the coupling groove 17 of the member 10 and the rotation of the member 11 to the member 10 is interrupted. Hereupon, the turn table 7 is fixed on the place where the section 3 is turned right forward fixed on the place where the section 3 is turned right forward in relation to the slewing base 2.
