Bearing unit and motor

A bearing unit comprising:

• an impregnated bearing that rotatably supports a shaft of a rotor;
• a storage part which is formed in a manner that an end surface of a housing incorporating the rotor in an axial direction becomes convex toward an outer side and which stores the impregnated bearing in a non-rotatable manner;
• and
• an oil return washer which is placed to face an end surface of the impregnated bearing stored in the storage part, the end surface facing a side of the rotor and which integrally rotates with the shaft, wherein
• the storage part has a bottom tubular shape having a constant cross-sectional shape that is orthogonal to the axial direction, and includes an inner surface that extends in the axial direction and a bottom surface that is orthogonal to the inner surface, and
• the oil return washer is placed in a manner that a facing surface of the oil return washer that faces the end surface of the impregnated bearing overlaps with the inner surface of the storage part when viewed from a radial direction, and includes a circulation part that is formed on the facing surface, receives oil leaked from the impregnated bearing, and returns the oil to the impregnated bearing.
