Abstract
A coupling device for connecting members, including: a coupling case that has a plurality of connecting slots which respectively receive the members; and wedges that are inserted into the spaces between the coupling case and each of the members perpendicularly to the direction of external pressure given to each of the members. Each of the wedges have one side and another side out of at least a couple of slope sides contacting the coupling case in opposite directions and have a higher coefficient of friction on a bottom side surface that touches one of the members than on the slope side surface that touches the coupling case.
