Claims

[Claims for Utility Model Registration] A driving rotating body is rotationally driven by a motor provided below the reel stand, and the driving rotating body rotationally drives the reel stand via an intermediate rotating body. In the reel stand rotation drive device configured, the intermediate rotating body is configured by a lower rotating body rotationally driven by the drive rotating body and an upper rotating body rotationally driving the reel stand, and these lower A rotation drive device for a reel stand, characterized in that a side rotary body and an upper rotary body are engaged with each other through external teeth and internal teeth.
