Device with at least two parts that can be moved relative to each other

摘要

The column has an adjusting element (8) including displacement along actuation direction, and two contact surfaces, where one of the surfaces is supported on an inner tubular part (1) by the other surface. A sliding element (6) moves toward a sliding surface (5) of an outer tubular part (2) by displacement of the adjusting element. The inner tubular part includes a recess (11) located outside an area in which the adjusting element is supported on the tubular part by the latter contact surface. A projection located on the sliding element is mounted in positive fashion along actuation direction.
