Abstract
A vibration stabilizer is provided for a power tool such as a sander or the like which has a pivotally oscillating driveshaft for supporting a tool head. The tool is provided with an elongate body having an internal cavity aligned along a longitudinal axis for receiving a drive motor therein. A driveshaft is pivotally supported upon the elongate body rotatable about a pivot axis. The drive motor operatively engages the driveshaft to cause the driveshaft to pivotally oscillate within a limited angular range when the drive motor is energized. Relative vibration between the tool head and the elongate body is minimized by an elastic ring which extends about the driveshaft and is interposed between the tool head and the elongate body. The elastic ring is loaded in compression axially biasing the tool head and the attached driveshaft in a direction away from the elongate body.
