Abstract
A reciprocating linear actuator in which a slide and a counter slide are arranged for linear movement within a hollow guide. The actuator has driving force generating means for generating a driving force between the slide and the counter slide and also has bearing structures formed individually between the guide and the slide and between the guide and the counter slide. If an external force acts on the slide, the external force is transmitted from the slide to the guide through the bearing structure between them.
