    Abstract: A washing machine with a wobbling unit including a washing plate which wobbles in a vertical direction without rotating, thus washing laundry. The wobbling unit further includes a vertical rotating shaft rotating by a washing shaft and an inclined rotating shaft provided at a predetermined position above the vertical rotating shaft. A first rotary member allows the vertical rotating shaft to rotate along with the inclined rotating shaft. A second rotary member rotatably receives the inclined rotating shaft therein. The wobbling unit also includes a projecting pin, a wobbling pin, and a leveling pin to control positions of the first and second rotary members. A position of the washing plate is changed to a level position or a wobbling position by an operation of the pins. Further, a clutch is mounted to the second rotary member so that the position of the washing plate is securely changed to a desired position.
