ABSTRACT:
A brush holding device for an electric motor of small size, with a brush cap being removably mounted to a brush holder so that a brush can be replaced. The brush cap is constructed such that a pair of elastic arms axially extend from the both sides of a coil retaining portion and a vertical wall is formed with a key hole for preventing the brush cap from radially slipping out of the brush holder.
