Abstract: A spinning reel has a rotary frame which is rotated around a spool and has two support arms for supporting a bail arm via a bail arm holder and a bail arm lever. In order to improve static and dynamic balances of the rotary frame, the bail arm holder is supported on the support arm so that a portion, on the opposite side of the bail arm in its winding position with respect to a reference plane of the bail arm holder is heavier than a portion, on the side of the bail arm of the bail arm holder, balancing means are integrally provided on the rotary frame, or the support arms are extended obliquely with respect to the reference plane.
