摘要：
The cord reel device comprises a first reel body and a second reel body which are linked so that their rotational axes coincide; a pullout cord that is wound around the first reel body so that it can be pulled out; an internal cord that is wound around the second reel body in the same direction as the winding direction of the pullout cord; and a reel case that rotatably covers the first reel body and the second reel body and forms a winding space that allows free play of the internal cord. A convex portion that protrudes toward the rotational axis is provided to the reel case.
