で変位することを特徴とするリール台駆動装置。 A driving rotating body 1 connected to a motor and a driven rotating body 2 that transmits rotational torque to the reel stand are arranged rotatably on the same axis, and a slip mechanism is interposed between both rotating bodies 1 and 2. In a reel stand drive device equipped with a locking mechanism that operates only when the rotating body 1 rotates at high speed and connects both the rotating bodies 1 and 2 so that they can rotate together, the locking mechanism is provided on the driving rotating body 1. It is composed of a connecting piece 5 that is elastically deformed by the centrifugal force accompanying the rotation of the rotating body, and a driven part 23 that is provided on the driven rotating body 2 and is engageable with the elastically deformed connecting piece 5. 1. A reel stand driving device characterized in that the connecting piece 5 is displaced to a position where it can engage with the driven part 23 during high speed rotation.
