Claims

[Claims for Utility Model Registration] (1) A bearing that supports a rotating shaft, a bracket that supports this bearing, an oil drain runner that is disposed between the bearing and the bracket, and a positioning device that is positioned by the bracket in the assembled state. In an oil draining device for a bearing part of a rotating electrical equipment, the spacer is positioned by a temporary fitting part provided on an oil drain runner during assembly, and the spacer has a coefficient of thermal expansion larger than that of the bracket material. An oil draining device for a bearing part of a rotating electric device, characterized in that it is made of a material. (2) The oil draining device for a bearing portion of a rotating electric device as set forth in claim 1, wherein the spacer is made of an organic polymeric elastic material.
