スト部材２４を介在させている。 In the figure, 12 is a motor, and a bearing metal 14 made of oil-impregnable metal such as sintered metal is attached to the frame 13 with a metal restraining spring 15.
The rotating shaft 16 of the motor 12 is supported by the bearing metal 14. The frame 13
An oil drain cover 17 having a shape surrounding the bearing metal 14 is attached to the inside of the bearing metal 14. This oil drain cover 17 has a pair of recesses 18 on the inside as shown in FIG.
Further, the portion of the motor 12 facing the rotor is open. A metal thrust receiving member 19 is arranged inside the oil drain cover 17 along the end surface of the bearing metal 14 facing the rotor, and the protrusion 20 on the outer periphery of the thrust receiving member 19 is connected to the oil drain cover 17.
The thrust receiving member 19 is fixed by fitting into the recess 18 of the thrust receiving member 19. The oil drain cover 17
Inside, and on both sides of the thrust receiving member 19, oil-impregnated members 21 and 2, such as oil-impregnated felt, are respectively applied.
2, one of which is in contact with the outer periphery of the bearing metal 14. A metal thrust member 24 is interposed between the thrust receiving member 19 and the stepped portion 23 of the rotating shaft 16.

する。 In the above configuration, the thrust load acting when the motor 12 rotates is applied to the contact portion between the metal thrust member 24 and the thrust receiving member 19. However, one of the oil-impregnated members 21 and 22 is in contact with the surface of the thrust receiving member 19 facing the rotor.
By supplying oil to the rotating contact portion between the thrust member 24 and the thrust receiving member 19, the rotational contact resistance can be reduced to allow the motor to rotate smoothly and to reduce noise. Further, fine metal powder generated by the friction between the thrust member 24 and the thrust receiving member 19 mixes into the oil, which turns the oil into a grease-like state, and this grease-like oil is scattered by rotation. Therefore, oil is permanently supplied to the rotating contact portion between the thrust member 24 and the thrust receiving member 19, and its lifespan is extended.
発明の効果

寿命も長くなるという効果をもつものである。Effects of the Invention As described in the above embodiment, even if the bearing of the vacuum cleaner motor of the present invention is subjected to a large thrust load due to a fan, etc., the thrust load is reduced by devising the structure in which the oil-impregnated member is incorporated. This enables smooth rotation and low noise, and since the thrust member is made of metal, there is less wear and tear.
This has the effect of lengthening the lifespan.
