置。 A rotating shaft of the electric motor, a ring-shaped bearing metal whose outer peripheral surface partially forms a spherical convex surface and is slidably fitted onto the end of the rotating shaft, and an inner part of the casing that supports the rotating shaft. In the support device for a rotating shaft for an electric motor, the supporting recess is formed on a side surface to a size such that the bearing metal can be freely inserted therein, and the supporting recess has a spherical concave surface facing the spherical convex surface of the bearing metal. This engagement is achieved by a groove formed on the inner peripheral surface of the metal, a felt provided inside the groove, an engagement recess formed in a part of the spherical convex surface, and a part of the spherical concave surface. It is characterized by having an engaging convex portion formed in a portion facing the mating recess, and a stop ring that is locked to an intermediate portion of the rotating shaft and prevents the bearing metal from moving away from the casing. A support device for the rotating shaft of an electric motor.
