    摘要: A spinning-type fishing reel is provided with a rear-actuated front drag. Concentric shafts are provided with a spool freely rotatable on one shaft. Drag members operate on the spool to provide drag to the spool. A drag knob on the rear of the reel operates on one of the shafts to shift the one shaft axially relative to the other, thereby applying pressure to the drag members and to the spool to increase the drag on the spool. In one form, the spool may be freely rotatable on a spool carrier which is keyed to one of the shafts. A spool cap attached to one of the shafts operates through the drag members to apply drag to the spool. The spool is urged against an abutment carried by the other shaft such that moving one shaft relative to the other by turning the rear-mounted drag knob either increases or decreases the drag on the spool.

    摘要: A fishing reel body includes a first side; a second line retrieval handle side opposite the first side; a bridge extending between the first and second sides, the bridge supporting a thumb rest portion; a convex surface on the second side configured to extend into the user's palm and an arcuate elevated contour on the second side and configured to extend within the notch between the user's thumb and index finger. The arcuate elevated contour preferably extends substantially adjacent to the thumb rest portion so as to support the user's thumb on the thumb rest portion away from the user's fingers.
