Abstract
A bolt-tightened type coupling includes a pair of semi-circular arc-shaped coupling halves having base ends which are pivotably connected to one another, so that the coupling halves can be moved toward each other to a closed position and moved away from each other to an open position. The coupling halves have opposite, free ends providing with flanges, respectively, having bolt inserting holes, respectively. One of the bolt inserting holes has such a shape that a bolt fits tightly with the inner edges of the bolt inserting hole, so that the bolt can be held by the bolt inserting hole.
