Acoustically optimized positioning device

Abstract

The invention relates to an actuating device for adjusting a vehicle flap or a vehicle door, comprising a housing (102), comprising a first housing part (103) and a second housing part (104), wherein the first housing part (103) is displaceable relative to the second housing part (104) along a longitudinal axis (L) of the housing (102) and the first housing part (103) and the second housing part (103) are made of a plastic, a preloading means (115) arranged in the housing, wherein the preloading means (115) preloads the first housing part (103) and the second housing part (104) against each other parallel to the longitudinal axis (L) of the housing (102). The ability to specify an actuating device which is cost-effective and durable and has the quietest possible operation, and to specify a method for manufacturing a housing part or guide element for an actuating device which is reliable and cost-effective, is achieved by the fact that at least the first housing part (103) consists of a mixture of a polymer with a sliding additive.
