ABSTRACT

An electric linear actuator comprises a housing extending along an axis, a
spindle in the housing and extending along the axis, a motor coupled to and
configured to rotate the spindle, and a rod coaxially coupled to the spindle
and axially movable with respect to the housing in response to rotation of the
spindle, the rod comprising a groove. A resilient member is configured to be
received in the groove to prevent back-drive of the motor when the rod is
subject to a load.
