FIELD: automotive industry.

SUBSTANCE: disclosed is device (1) for transfer of waste gas between front (3) and rear (3) carriages of working machine separated by swivel joint (2). Device includes a variable length tubular section (5) for conducting waste gas, first flexible pipe (6a), which interacts with the first end area of tubular section (5), in order to introduce waste gas into tubular section (5), and second flexible pipe (6b), which interacts with second end area of tubular section (5), to discharge exhaust gas from tubular section (5). In first end area (8a), first articulated shaft (7a) is provided, the distal end of which is made for rigid installation on attachment section (9a; 9b) of front carriage (3) or rear carriage (4) of working machine, and in the second end area (8b) there is a second articulated shaft (7b), the distal end of which is made for rigid installation on attachment section (9a; 9b) of front carriage (3) or rear carriage (4) of the working machine, note here that first articulated shaft (7a) is fitted in first pipe (6a) while second articulated shaft (7b) is fitted in second pipe (6b).

EFFECT: invention is aimed at simplifying the design, as well as improving reliability and manufacturability of the device for transfer of waste gas between carriages of a working machine.
