An underwater drilling lever device capable of easily driving a drilling lever as a mooring index into a bottom and extracting it from the bottom with small labor in a short time. The underwater drilling lever device comprises a lever body (12) vertically installed in the bottom with the lower end thereof buried in the drilled sludge layer of the bottom (308) and the upper end thereof projected from a water surface. The lever body further comprises a drilling body (14) installed at the lower end of the lever body (12) and drivingly drilling the bottom with a rotating input around the longitudinal axis given t hereto from a water surface projected part (12a) and a rotating input receiving part (16) fitted to the water surface projected part (12a) of the lever body and rotating the lever body around the longitudinal axis by receiving the rotating input by an input means (46). The lever body is formed by detachably connecting the plurality of lever bodies to each other in the longitudinal direction. Since the drilling body at the lower end of the lever smoothly drivingly drill the bottom while rotating with the rotating input given thereto from the water surface, a vertical installation operation can be easily completed in a short time.
