PROBLEM TO BE SOLVED: To improve the efficiency of greasing work to a swing device by arranging filling ports convergently in a position that can be reached from the circumference. SOLUTION: The front filling port 18 and the rear filling port 19 are convergently arranged at the left end of a swing frame 6 on the lower side of a cab 7. The front filling port 18 is connected to a front greasing port 15 provided at an outer wheel 12 of the swing device 10 using front piping 21, while the rear filling port 19 is connected to a rear greasing port 16 using rear piping 22. A grease gun 20 can thereby be easily connected to the respective filling ports 18, 19 arranged at the left end of the swing frame 6. If the grease gun 20 is sequentially connected to the respective filling ports 18, 19, grease can be supplied to movable parts of the swing device 10 from two greasing ports 15, 16, and greasing work to two parts can be performed from one part in the left side position of the cab 7.
