Driving Device Lubrication Structure

原文（中国語）

Proposed is a driving device lubrication structure. The driving device lubrication structure includes a main body, a sub-body configured to perform a relative movement with multiple degrees of freedom with respect to the main body within a predetermined range and configured such that at least a portion of the sub-body is capable of being rotated by a rotational force transmitted from the main body, a driving device provided within the sub-body and configured to shift the rotational force, an oil pump provided in the main body and configured to supply oil to the driving device, a supply pipe mounted such that oil that the oil pump supplies can be supplied to the sub-body while the relative movement can be performed, and a return pipe configured such that oil in the sub-body is capable of being returned to the oil pump while the relative movement can be performed.
