Abstract
A linear motion device includes a housing, an extension arm, and an anti-twist safeguard. The extension arm projects from the housing and includes a securing section. The anti-twist safeguard includes at least one separate elongate anti-friction lining, which is formed with a constant cross-sectional shape. The anti-friction lining is arranged substantially without play between the housing and the securing section of the extension arm and extends transversely to a longitudinal axis. The extension arm is supported on the housing in such a way that it can move along the longitudinal axis. In the securing section, the extension arm extends parallel to the longitudinal axis with a constant external cross-sectional shape deviating from a circular shape. The anti-twist safeguard engages positively in said external cross-sectional shape, thus securing the extension arm with respect to the housing against twisting relative to the longitudinal axis.
