    Patent number: 11141837
    Abstract: A clamp rod (2) is inserted into a housing so as to be movable in a vertical direction. An attachment hole (6) is provided at a left end portion (3a) of a clamp arm (3), which is attachable to and detachable from the clamp rod (2). The attachment hole (6) passes through the left end portion in the vertical direction. An accommodation hole (8) is provided at a position to the upper right of the attachment hole (6). A transmission member (10) and a wedge member (15) configured to be brought into wedge engagement with the transmission member (10) from above are inserted into the accommodation hole (8). At the time of attaching the clamp arm (3) to the clamp rod (2), the wedge member (15) is pressed downward using a tightening bolt (21), and thereby the wedge member (15) presses the attachment hole (6) via the transmission member (10) and the clamp rod (2), and presses the accommodation hole (8).
