Abstract
A connecting device connecting a remaining bar and a movable bar of a transfer bar includes a remaining-side clamp and a movable-side clamp. The clamps respectively have a male fitted portion and a female fitted portion that are fitted to one another around a connecting direction, defining a first connector. A male engagement portion and a female engagement portion are provided inside the clamps, defining a second connector. The female engagement portion of the second connector includes a sphere in a form of a movable member moving in a direction orthogonal to the connecting direction. A movement of the sphere effects an engagement and disengagement of the female engagement portion from the male engagement portion.
