A spinning-reel reel unit has a housing unit, a first lid, a second lid, a rod-attachment
portion, and a cover member. The housing unit has a housing space formed therein
for accommodating and supporting a drive mechanism. The first lid is fixedly coupled
to a side of the housing unit detachably/reattachably, and includes a first cover
portion and a first cut-out. The second lid is fixedly coupled to another side
of the housing unit detachably/reattachably, and includes a second cover portion
and a second cut-out. The rod-attachment portion is formed integrally with the
housing unit and is adapted to be mounted onto a fishing rod. The cover member
covers both of the cut-outs of when the lids are fitted to the housing unit. In
the spinning-reel reel unit, weight reduction can be achieved even when a cover
member is provided.
