PROBLEM TO BE SOLVED: To attach a clamp arm of a clamp device to a clamp rod easily.SOLUTION: A clamp rod (5) is inserted into a housing movably in a vertical direction. An attachment hole (11) is vertically inserted into a left end part (10a) of a clamp arm (10) to be detachably attached to the clamp rod (5). A wedge member (15) which becomes a taper-shape downward, is attached to a storage hole (13) formed on a right and upper side of the attachment hole (11). When the clamp arm (10) is attached to the clamp rod (5), the wedge member (15) is downward pressed by a tie bolt (20), so that, the wedge member (15) presses the attachment hole (11) via the clamp rod (5), and presses the storage hole (13).SELECTED DRAWING: Figure 2 |
