る旋回式建設機械。 It has an undercarriage body and an upper revolving body supported by the undercarriage body in a swinging manner via a swing device, the swing device being fixed to the undercarriage body side and having an internal gear on an inner circumferential surface. A swing ring consisting of a formed inner ring and an outer ring fixed to the upper revolving body side and rotatably engaged with the inner ring via steel balls; It consists of a swing motor device having an output shaft having a pinion that meshes with the internal gear, and a grease bath that surrounds the meshing portion of the internal gear and the pinion,
In the swing type construction machine, the casing of the swing motor device is provided with a seal device for sealing the casing side and the output shaft side, and the seal device prevents gear oil in the casing from leaking into the grease bath. A swing type construction machine comprising: an oil seal that prevents the oil from entering the casing; and a grease seal that prevents the grease from penetrating into the casing by pushing up the grease from the grease bath side.
