A fishing-rod attachable dual-bearing reel body on a lateral surface of which a handle is disposed and interiorly in which a spool is disposed on a shaft, the dual-bearing reel body comprising:

• a frame having a pair of side-plates between which the spool is disposed and connecting members for connecting the side-plates;
• a pair of side-covers exteriorly covering either side-plate, said handle being mounted on a proximal one of the pair of side-covers;
• and
• a fishing rod mount disposed between the pair of side-plates for attachment to a fishing rod;
• wherein
• on the side in which the handle is mounted, said proximal side-cover together with a proximal one of the side-plates constitute a first cylindrical portion interiorly having a columnar first space, and a second cylindrical portion staggered such that the outer circumference of the second cylindrical portion intersects the outer circumference of the first cylindrical portion, therein protruding outward in the spool shaft direction with respect to the first cylindrical portion and interiorly having a columnar second space communicating interiorly with the said first space.
