  • the object of the present invention is to provide a drawer front connecting device of the type described in the introduction in an improved manner, in particular with regard to a simple and exact height and / or lateral adjustment of the drawer front.
  • the invention is based on a drawer front adjusting device for adjusting a drawer front relative to a drawer side part in an adjustment direction, in particular for lateral adjustment of the drawer front.
  • the drawer front adjustment device is preferably designed as a height adjustment device for the drawer front or as a side adjustment device for the drawer front.

This allows the drawer front to be adjusted vertically or sideways or in the width direction in, for example, 0.5 millimeter steps.
  • the frictional resistance when rotating the adjusting element or against the rotational movement imposed from the outside is preferably alternately strong and weak noticeable for the fitter during Rotating the actuator.
  • the frictional resistance is alternately clearly perceptible and disappearing or not perceptible or alternately perceptible increasing and decreasing.

In addition, a number of areas are available on the housing, which can be adapted to the requirements for providing the friction surfaces.
  • a friction surface of the friction structure is designed as a raised structure.

  • the friction structure comprises a plurality of friction surfaces arranged circumferentially to the longitudinal axis of the actuating element and separated from one another in the circumferential direction. This is an advantageous embodiment due to the relative movement of the rotatable adjusting element and the mating section, which is generally fixed in position.

  • the friction structure has a friction surface which is formed on an edge of a through opening in the housing through which a section of the actuating element extends.
