Abstract
A hand-held power tool is equipped with a dust extraction device which includes a dust box for holding dust. A closing flap is arranged in a tube section which lies in the flow path to the dust box, and this closing flap can be adjusted between the closed position and the open position. The closing flap is pivotably held in the region of the inner wall of the tube section and can be opened in the direction of the dust box. In the closed position, the closing flap bears against a stop which protrudes into the tube section, extends at an angle with respect to the direction of flow through the tube connection piece, and forms a stop line or stop area against which the closing flap correspondingly bears.
