Claims

[Scope of utility model registration request]

(1) A substantially cylindrical inner draining member that extends toward the tip of the rotating shaft and covers the outer periphery of the rotating shaft, with one end fixed to the motor body and the other end protruding from the main body; one end is fixed, the other end extends in the direction of the tip of the counter-rotating shaft so as to cover the outer periphery of the tip of the draining member, and has annular protrusions on the outer circumferential surface and the part facing the outer periphery of the tip of the draining member, respectively. and a substantially cylindrical outer cover that extends from the motor main body side toward the tip of the rotating shaft and covers a position facing the annular protrusion on the outer periphery of the inner drain lid. A rotary shaft draining device for an electric motor.

(2) The rotation of the electric motor according to claim 1, wherein the opening diameter of the opening end on the tip side of the rotating shaft of the outer cover is formed smaller than the outer diameter of the annular protrusion on the outer periphery of the inner draining lid. Shaft drainer.

(3) A rotary shaft draining device for an electric motor according to claim 1 or 2, wherein the outer cover is fixed to the electric motor body.

(4) The inner draining lid is made of an elastic member, and is equipped with a retaining ring that is fitted onto the inner periphery of the open end on the tip side of the rotating shaft, and is fitted to the stepped part on the outer periphery of the rotating shaft. A rotary shaft draining device for an electric motor according to any one of claims 1 and 3 of the patent registration claims.
