Abstract
A linear actuator includes a housing with an electric motor, which through a transmission drives a spindle with a spindle nut. To the spindle nut is secured a tubular adjustment element, which is guided in a guide tube. A bushing is secured at the rear end of the guide tube for securing the guide tube to the chassis of the actuator. Expediently, the securing is done with stampings from the outer side of the mounting bushing and into the guide tube. These stampings are appropriately done opposite channels, such as screw channels in the guide tube, such that the stampings are received in the channels and do not protrude into the guide tube and prevent the movement of the spindle nut and the adjustment element.
