Abstract: A power strut for raising and lowering a liftgate of an automotive vehicle includes an outer housing tube carrying a first attachment element for attaching the power strut to a vehicle. A spindle bearing an outer thread is rotatable relative to the outer housing tube via an electric motor. The spindle is axially stationary relative to the outer housing tube. A spindle nut having an inner thread meshing with the outer thread of the spindle is displaceable along the longitudinal axis. A nut tube is rigidly connected to the spindle nut and surrounds the spindle. A second attachment element is located opposite the first attachment element. The first attachment element has a first snap structure that is complementary to a second snap structure formed on the outer housing tube. The first and second snap structures non-rotatably secure the first attachment element to the outer housing tube.
