PURPOSE:To prevent mutual interference of front/rear chassis by integrally providing two stoppers for limiting articulation and oscillation to a member for coupling the front/rear chassis rotatably in horizontal direction while rollably around the axis in backward/forward direction. CONSTITUTION:A working car such as an articulate steering shovel loader has front and rear chassis 2, 3 to be coupled through coupling mechanism 4. The coupling mechanism 4 is constructed by fixing a coupling member extending in backward/forward direction or an oscillate pin 17 rotatably in horizontal direction to an articulate pin 16 journaled between upper and lower plates 15, 15 of front chassis frame 14. Here, the oscillate pin 17 is formed with a stopper (projection) 21 contactable against a stopper 25 at the front chassis 2 side to control the articulate and second stopper 23 contactable against a stopper 28 provided at the rear chassis 3 side to control oscillate. |
