Claims

[Claims for Utility Model Registration] (1) A permanent magnet fixed to one end of a rear bracket made of a magnetic material, a front bracket made of a magnetic material that faces the permanent magnet with a gap in the axial direction, and the above permanent magnet and An armature that is rotatably supported between the front brackets and has a built-in coil, a commutator that is connected to the coil and projects axially from the rear bracket, a brush that comes into contact with the commutator, a rotating shaft that rotates together with the commutator, and a rotary shaft that rotates integrally with the commutator. In a device equipped with a detector fixed to a rotating shaft, a bearing for supporting the rotating shaft is interposed between the commutator and the detector, and
A flat motor characterized by this bearing being attached to the inner circumference of an adapter fixed to the rear bracket. (2) The flat motor according to claim 1, wherein a cover for covering the adapter and the detector is fitted onto the outside of the adapter.
