A left vehicle width expanding/contracting device (15) expands and contracts a vehicle width of a lower traveling structure (4) by moving a left side frame (6) in the right-and-left direction relative to a center frame (5) by extending and contracting a rod (16B) of a hydraulic cylinder (16), and similarly, a right vehicle width expanding/contracting device expands and contracts the vehicle width of the lower traveling structure (4) by moving a right side frame in the right-and-left direction. The hydraulic cylinders (16) of the left and right vehicle width expanding/contracting devices (15) are each located between a drive wheel (9) and an idler wheel (10) and each mounted on the side frame (6).
