<p>A housing for a power tool, such as a circular power saw, having an access aperture for mounting the brushes of a universal motor which is journaled in the housing. Tabs hold the brushes within a recess, and screws are threadedly connected to the housing to clamp the tabs. A cover is substantially "U" shaped and has posts extending inwardly in superposition to the screws to prevent the screws from backing out due to vibration or other loosening thereof. The cover fits between an upper and a lower housing extension and provides a smooth continuous outer configuration, through which vent slots permit the passage of cooling air.</p> |
