Abstract
An actuator has a worm gear which drives a pair of flexible parts into a guide where they are united to form a rigid transmission member. The parts have interlocking teeth which cooperate with each other to transmit stresses in compression and tension along the transmission member. Because the parts are flexible in a direction transverse to the direction of the guide, they may be stored in a space-saving manner to the sides of the guide.
