Dual-bearing reel and reel unit for same

A dual-bearing reel, comprising:

• a reel unit, the reel unit for supporting a spool in a rotatable state, the reel unit including
• a frame including a first side plate, a second side plate disposed in opposition to the first side plate to enable the spool to be disposed between the first side plate and the second side plate, and a plurality of coupling members integrally formed with the first side plate and the second side plate to couple the first side plate and the second side plate;
• a fishing rod attachment leg fixed to an outer surface of one of the plurality of coupling members;
• and
• a thinned part having a recessed shape and formed on an inner surface of the one of the coupling members to which the fishing rod attachment leg is fixed, the inner surface faced to the spool, wherein a bottom of the thinned part is surrounded by an edge disposed on four sides of the thinned part,
• the spool;
• and
• a handle for rotating the spool, the handle rotatably supported by the reel unit on the same side as the first side plate.

A method of manufacturing a reel unit for a dual-bearing reel, the reel unit for supporting a spool in a rotatable state, the method comprising:

• disposing, in a frame including a first side plate, a second side plate in opposition to the first side plate to enable the spool to be disposed between the first side plate and the second side plate, a plurality of coupling members integrally formed with the first side plate and the second side plate to couple the first side plate and the second side plate;
• fixing a fishing rod attachment leg to an outer surface of one of the plurality of coupling members;
• and
• forming a thinned part, having a recessed shape, on an inner surface of the one of the coupling members to which the fishing rod attachment leg is fixed, the inner surface faced to the spool, wherein a bottom of the thinned part is surrounded by an edge disposed on four sides of the thinned part.
