Claims

[Scope of utility model registration request]

A bearing housing is formed into a dish shape that opens toward the rotor, is fixed to the substrate side, and has a spherical support surface in the center, and a spherical surface at one end is rotatably fitted to the spherical support surface to support the rotor shaft. a plate spring member formed into a disk shape by a spring member and fitted onto the rotor shaft with a plate-shaped portion attached to the other spherical end of the bearing; A bearing device for an electric motor, comprising: a spring retainer that is fitted onto the rotor shaft and whose outer circumferential portion is press-fitted into the outer circumferential concave portion of the bearing housing while elastically deforming the leaf spring member and bringing it into pressure contact with the attached spherical surface; A plurality of voice pieces are provided on the outer circumference of the spring member so as to project in the axial direction of the rotor shaft, the tips of which are brought into substantially contact with the dish-shaped bottom surface of the bearing housing when attached to the bearing spherical surface. Bearing device for electric motor.
