駆動力伝達装置。[Claims for Utility Model Registration] A center pin set on a turntable is inserted into a center hole drilled in the center of a core body to which a plate-shaped recording medium is fixed, and the recording medium is placed on the turntable. In a rotational driving force transmission device that transmits rotational driving force by being placed on the center pin, a protruding and retracting member is provided on the center pin that protrudes in the radial direction when rotating and is entirely housed within the center pin when non-rotating, and the protruding member that protrudes from the core body. A rotational driving force transmission device characterized in that a recessed portion extending radially from the center hole is provided that can be engaged with the protruding and retracting member in the state.
