A construction machine, comprising: a lower propelling body; and an upper slewing body loaded on the lower propelling body to be slewable about an axis vertical to the ground, wherein: the upper slewing body includes an upper frame, a cab provided on a left portion or a right portion of the upper frame and configured to allow an operator to enter therein, and a plurality of cab mounts (14, 15, 16, 17A, 17B) interposed between the cab and the upper frame; the cab mounts (14, 15, 16, 17A, 17B) are disposed at lateral ends on each of a front portion and a rear portion of the cab respectively and configured to exert a resistive force against a load acting on the cab in such a direction as to remove the cab from the upper frame when the construction machine rolls over; characterized in that the cab mounts (14, 15, 16, 17A, 17B) include, on at least one of the front portion and the rear portion of the cab, a first outer-side cab mount and a second outer-side cab mount which are disposed at an outer side of the lateral ends of the cab, the first and second outer-side cab mounts (17A, 17B) being juxtaposed with a small enough distance to allow the first and second outer-side cab mounts (17A, 17B) to receive the load concurrently when the construction machine rolls over toward a side of the cab. a lower propelling body; and an upper slewing body loaded on the lower propelling body to be slewable about an axis vertical to the ground, wherein: the upper slewing body includes an upper frame, a cab provided on a left portion or a right portion of the upper frame and configured to allow an operator to enter therein, and a plurality of cab mounts (14, 15, 16, 17A, 17B) interposed between the cab and the upper frame; the cab mounts (14, 15, 16, 17A, 17B) are disposed at lateral ends on each of a front portion and a rear portion of the cab respectively and configured to exert a resistive force against a load acting on the cab in such a direction as to remove the cab from the upper frame when the construction machine rolls over; characterized in that the cab mounts (14, 15, 16, 17A, 17B) include, on at least one of the front portion and the rear portion of the cab, a first outer-side cab mount and a second outer-side cab mount which are disposed at an outer side of the lateral ends of the cab, the first and second outer-side cab mounts (17A, 17B) being juxtaposed with a small enough distance to allow the first and second outer-side cab mounts (17A, 17B) to receive the load concurrently when the construction machine rolls over toward a side of the cab. the upper slewing body includes an upper frame, a cab provided on a left portion or a right portion of the upper frame and configured to allow an operator to enter therein, and a plurality of cab mounts (14, 15, 16, 17A, 17B) interposed between the cab and the upper frame; the cab mounts (14, 15, 16, 17A, 17B) are disposed at lateral ends on each of a front portion and a rear portion of the cab respectively and configured to exert a resistive force against a load acting on the cab in such a direction as to remove the cab from the upper frame when the construction machine rolls over; characterized in that the cab mounts (14, 15, 16, 17A, 17B) include, on at least one of the front portion and the rear portion of the cab, a first outer-side cab mount and a second outer-side cab mount which are disposed at an outer side of the lateral ends of the cab, the first and second outer-side cab mounts (17A, 17B) being juxtaposed with a small enough distance to allow the first and second outer-side cab mounts (17A, 17B) to receive the load concurrently when the construction machine rolls over toward a side of the cab.
