The gripping device is proved with a rode portion (2) which is movable vertically along a rod axis (O), to the lower end of which is mounted a connecting block (41), a pair of opening and closing lever portions (3) disposed to face each other along the direction of a fore-to-aft or lateral axis (L1), intermediate portions (3c) of which being pivotal about a fulcrum support shaft portion (50) parallel to a left-right or longitudinal axis (L2), and a link mechanism (4) which connects the connecting block (41) and the upper ends (3a) of the pair of the opening and closing lever portions (3) and pivots the pair of the opening and closing lever portions (3) in the direction of fore-to-aft axis in response to the vertical movement of the rod portion (2). The pair of the opening and closing lever portions (3) is formed with a cutout or notch (55) at least extending from the intermediate portions to upper ends. The pair of the opening and closing lever portions (3) is disposed to each other with the rod portion (2) and connecting block (41) accommodated in a space of the cutout (55) and the respective upper ends (3a) are disposed on both side of both the rod portion (2) and connecting block (41), along the direction of the fore-to-aft axis. |
