At least one inclined surface for guiding the carrier can be arranged on the carrier and/or on the mounting body, with the carrier being movably mounted along the inclined surface in a direction transverse to the axis of rotation when an operating element is rotated about an axis of rotation. This results in a simple construction for deflecting a movement of the carrier in a direction transverse to the axis of rotation of the operating element.

According to a further exemplary embodiment, it can be provided that the mounting body has a length and a height, the length of the mounting body being at least three times, preferably at least six times, the height of the mounting body. In this way, the furniture fitting can be made particularly compact, so that the mounting body can be arranged within a predetermined material thickness of the furniture panel (for example with a material thickness of 16 mm or 19 mm).

The carrier can be designed either in one piece or in two or more parts. Likewise, the assembly body can be formed in one piece or in two or more parts.

According to one exemplary embodiment, it can be provided that the mounting body of the first fitting part can be inserted into a recess in a furniture panel, so that the mounting body is accommodated in a mounted state on the furniture panel for the most part, preferably essentially completely, within the recess in the furniture panel. This results in a compact and visually unobtrusive arrangement of the mounting part on the furniture body.
