ABSTRACT:
A bearing device having a sleeve bearing for small-sized dynamic electric machines, comprising a bearing support member of a rotary shaft supporting end bracket, and an inside annular projection which has a plurality of groove type inside oil reservoirs in the inner circumferential surface thereof and which is formed integrally with the bearing support member by a die casting mold. These inside oil reservoirs are provided in the same circumferential positions as oil returning bores in the bearing support member so as to be linearly communicated therewith. Owing to this construction, inner caps on the bearing support member, which are essential to a conventional bearing device of this kind, can be omitted. This allows the number of parts and the number of manufacturing steps to be reduced, and oil leak from inside caps as in a conventional bearing device can be prevented.
