Claims

[Scope of utility model registration request]

It has a lower traveling body and an upper rotating body rotatably supported by the lower traveling body via a rotating device, the rotating device is fixed to the lower traveling body side, and an internal gear is formed on the inner peripheral surface. an inner ring fixed to the upper revolving body and rotatably engaged with the inner ring via a steel ball, a swing motor device attached to the upper revolving structure, and an output shaft of the swing motor device. A revolving construction machine comprising a pinion that is provided and meshes with the internal gear, and a grease bath that surrounds the meshing part between the internal gear and the pinion and supplies grease to the meshing part, on the side of the upper revolving body. A revolving construction machine, characterized in that it is provided with a blade that partitions the inside of the grease bath only during grease replacement work and scrapes up the grease inside the grease bath by rotating the upper revolving body.
