In the underwater measurement device shown in Fig. 7, diving work is required by divers for installation on the sea floor and data collection, and safety measures for divers and large expenses for large-scale sea floor work are required. I need. Therefore, in a storage body that has an underwater measurement unit that measures underwater information such as wave height and is installed on the bottom of the water,
It is conceivable to store a cable drum that is remotely driven from a support ship or the like and winds or unwinds a cable with a float, and installs on the sea floor or collects data via the cable with a float. However, although miniaturization is required for installation on the sea floor, cable drums used on land are longer because the cable drum and the drive motor are longer in series and a traverse guide for aligned winding is interposed. In other words, there is a problem that the size of the underwater measuring device is unavoidable in view of application in the sea.

The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a miniaturized underwater measuring device that houses a cable drum that winds or unwinds a cable with a float. The purpose is to provide.
