動装置。 A first rotary body that receives rotational force from a rotational drive source and rotates as appropriate, a driving protrusion that engages with an engagement protrusion of a reel hub of a cassette tape to receive rotational force, and a drive protrusion that receives rotational force from the cassette tape in the axial direction. an inclined protrusion that engages with the engagement protrusion and provides relative rotation between the reel hub and the reel hub when the reel hub is moved and the engagement protrusion of the reel hub is in a position where it can come into contact with the end of the drive protrusion; a second rotary body coaxially with the first rotary body and engaged with the first rotary body in the rotational direction with at least a play capable of absorbing rotation due to the action of the inclined protrusion; The reel hub is configured to transmit the rotational force from the rotational drive source to the reel hub via the first and second rotary bodies to drive the reel hub of the cassette tape. When the reel hub moves in the axial direction and the engaging protrusion of the reel hub is in a position where it can come into contact with the end of the reel driving protrusion of the second rotating body, the action of the inclined protrusion and the play causes the second A reel drive device characterized in that a rotating body is rotated on a first rotating body.
