# Coupling structure and parallel link robot

## Abstract

The coupling structure includes: a pair of attachment members that are supported on two links) that each have a longitudinal axis and move parallel to each other with a gap therebetween so as to be able to rotate about rotation axes that are perpendicular to a plane that includes the longitudinal axes of both the links; and a coupling mechanism that fixes the distance between the pair of attachment members in an adjustable manner.
