[Problem] In regard to a hydraulic hose that extends from a center frame side in a lower travel body and is connected to a travel motor in each of right and left travel sections, it is possible to limit a movement range of a hydraulic hose with a simple configuration and thus to suppress damage to the hydraulic hose. [Solution] A lower travel body 20B that supports an upper unit includes: a center frame 5 that supports the upper unit; a side frame 70 that is provided on both of right and left sides of the center frame 5 to support a travel motor 71 and constitutes a crawler-type travel section 6; and plural hydraulic hoses 90, one end side of each of which is connected to a swivel joint 56 provided to the center frame 5, and the other end side of each of which is connected to the travel motor 71. The center frame 5 includes: a rear wall 53 having a guide hole 53a, through which the hydraulic hose 90 passes; and a hose guide 110 that is located below the guide hole 53a, located above the hydraulic hose 90, and thereby restricts upward movement of the hydraulic hose 90.
