Claims

[Scope of utility model registration request]

In a DC rotating electric machine in which an oil-impregnated bearing whose outer periphery is surrounded by a lubricating gasket is supported between the outside of an end bracket and the inside of a bearing presser spring, and an oil scattering prevention cover is attached to the outside of the bearing presser spring, the bearing presser is An oil flow hole is formed in the spring, and a partition ring is formed inside the oil scattering prevention cover, the inner diameter of which is larger than the diameter of the part where the oil flow hole is formed, and whose tip abuts the outer wall of the bearing presser spring. Characteristic DC rotating electric machine.
