Abstract: An electric motor includes an end wall having a collector mounted therein. The brushes of the motor are affixed to spring levers resiliently mounted on the end wall. The end wall includes a diaphragm-like portion having a release pin extending radially inward. The spring lever with the affixed motor brush is maintained in a mounting position by contact with a holding pin. After the assembly of the collector between the brushes, the diaphragm is compressed to push the release pin into the lever. The lever is freed from contact with the holding pin and is released to allow the brush to contact the collector.
