Bait cast reel having non-separating tension knob

A bait cast reel comprising:

• a reel body having a spool shaft rotatably installed thereon;
• a cylindrical frame coupled to an opening on a side of the reel body, having a first threaded portion on an outer side thereof, and having an elastic protrusion movably formed to generate a click;
• a click plate rotatably coupled to an opening on a side of the frame and having click grooves circumferentially formed on a floor thereof to generate a click by clicking the elastic protrusion when rotating;
• a control plate supporting the spool shaft and coupled to a through-hole of the click plate to integrally rotate;
• a non-separating tension knob having a second threaded portion that corresponds to the first threaded portion of the frame and is formed on an inner circumferential edge thereof, having a flange of the control plate integrally fixed to an internal floor thereof, and rotating the control plate to adjust tension of the spool and generate a click when rotating;
• a protruding step formed on an outer end of a wing-shaped protrusion formed to face the flange of the control plate;
• and
• a ring-shaped locking step formed on an inner circumferential edge of the click plate,
• whereby when the non-separating tension knob is fully unwound and loosened to adjust tension of the spool, the non-separating tension knob is locked to the locking step, so separation of the non-separating tension knob from the reel body is prevented.
