Claims

[Scope of utility model registration request]

A gate-shaped bridge is installed on the left and right side frames of the chassis to straddle the engine, and the left and right ends of the leaf springs are pivotally connected to brackets protruding from the left and right shoulders of the gate-shaped bridge, respectively. In a cab suspension structure in which a latch is provided in the center of the leaf spring to fix the rear end of the lower surface of the cab, the latch is interposed between the left and right ends of the leaf spring and the left and right brackets, respectively. The cab suspension structure is characterized by a hollow rubber bush that resists with a large amount of elasticity in the vertical direction, but with a small amount of elasticity in the width direction.
