PROBLEM TO BE SOLVED: To provide a clamping device for a covering plate, capable of surely clamping adjacent covering plates to each other while avoiding the interference between the clamping devices thereof.SOLUTION: A clamping device for a covering plate comprises: a mounting bracket 21 attached to an underside 11 of the covering plate 10; a clamp 30 rotatably provided on the mounting bracket 21 via a support shaft 25; a nut 51 unrotatably and slidably engaged with the clamp 30; and an operation bolt 50 penetrating through the underside 11 of the covering plate 10 and the mounting bracket 21 and screwed in the nut 51. Rotary operation of the operation bolt 50 makes the clamp 30 vertically rotate around the support shaft, and the support shaft 25 is pivotally supported so as to slide along an inclined guide hole 26. |
