A first embodiment of the present invention will be described below with reference to FIGS. 2 to 4 of the drawings. Reference numeral 1 denotes a bottomed cylindrical casing made of aluminum diegast, in which a stator core 3 around which a coil 2 is wound is fitted and disposed on the upper part of the inner circumferential wall of the casing 1, and a motor is mounted on the lower part of the circumferential wall. A protruding piece 4 for mounting is provided, and a cylinder 5 is integrally erected toward the inner surface of the center of the bottom of the casing 1, and a bearing 6 made of a sintered alloy is fitted onto the inner peripheral surface of the cylinder 5. , is fixed with a retaining ring 7. A rotor 8 is disposed between the cylindrical body 5 and the stator core 3, and a shaft 11 is rotatably inserted into the shaft insertion hole 9 of the bearing 6 and locked in the axial direction by a retaining ring 10. The rotor 8 is fixed to one end of the shaft 11. Further, a recess 12 communicating with the shaft insertion hole 9 of the bearing 11 is formed in the outer surface direction at the center of the bottom of the casing 1, and an oil-impregnated material 13 made of cellulose or the like impregnated with oil is accommodated in the recess 12,
Oil from the oil-containing material 13 is supplied to the sliding portion between the bearing 6 and the shaft 11 to prevent wear due to lack of oil in the bearing 6,
The bearing 6 is designed to have a long life. Furthermore, a cover 14 made of an aluminum plate with an adhesive layer 14a formed on the entire surface of one side is adhered to the bottom outer surface of the casing 1 to cover the recess 12 and seal it so that the oil in the oil-impregnated material 13 does not leak to the outside. At the same time,
The oil-impregnated material 13 is adhered and fixed to the cover 14 so that even if the shaft 11 rotates, the oil-impregnated material 13 does not rotate together. A small hole 15 for air venting is formed in the center of the cover 14, and the other side of the cover 14 is printed with motor specifications and serves also as a rating plate.

As described above, in the present invention, a stator core is disposed in a bottomed cylindrical casing, and a cylindrical bearing portion having a shaft insertion hole is erected toward the inner surface of the center of the bottom of the casing, and the stator core is disposed in a bottomed cylindrical casing. A rotor is disposed between the shaft and the stator core, and the rotor is fixed to one end of a shaft that is rotatably inserted into the shaft insertion hole of the bearing portion, and the rotor is fixed to one end of a shaft that is rotatably inserted into the shaft insertion hole of the bearing portion. A recess that communicates with the casing is formed in the outer surface direction at the center of the bottom of the casing, and the oil-impregnated material is accommodated in the recess, and the recess is covered with a plate-like cover having an adhesive layer formed on the entire surface of one side, so that the cover is fixed. When the shaft is rotated, no load is applied to the bearing, which prevents deformation of the bearing, and there is no need for sealing gaskets as in conventional models.Furthermore, the oil-impregnated material is adhesively fixed to the cover, so even when the shaft rotates, the oil-impregnated material remains. Since the materials do not rotate together, there is no oil splashing and a reliable seal can be achieved.
