Claims

[Scope of utility model registration request]

It consists of an armature that rotates by cutting the magnetic flux formed between the magnet and the casing, a commutator that rotates with this armature, a rotating shaft that connects the armature, and a sintered oil-impregnated metal that supports this rotating shaft. In a DC motor having a bearing and a plurality of brushes whose tips abut against the commutator and are arranged in a predetermined positional relationship with each other, the outer periphery of the bearing is formed into a cylindrical shape, and the bearing is Fits into the housing,
A DC motor including this bearing housing supported by the casing.
