Clutch mechanism for a double bearing fishing reel

A clutch mechanism for a double bearing fishing reel provided with a rotatable spool and a driving mechanism for driving said spool, said clutch mechanism comprising:

• first and second driven clutch pins rotatable together with said spool and extending perpendicularly to the axis of said spool, each of said driven clutch pins having a round cross section;
• and
• a rotatable clutch cylinder which is movable axially of said spool, said clutch cylinder comprising:
• first and second engaging recesses engageable with said first and second driven clutch pins, respectively, each of said engaging recesses having a bottom surface, first and second upper edges, and first and second side surfaces which extend from said bottom surface to said first and second upper edges, respectively, the distance from said second upper edge to said bottom surface being greater than the distance from said first upper edge to said bottom surface, and the distance from said first upper edge to said bottom surface being greater than the radius of said round cross section of said clutch pins;
• and
• first and second sloping planar guide surfaces extending from said second upper edges to said first upper edges of said engaging recesses, respectively, each of said sloping guide surfaces being located within a plane which is slanted with respect to a plane which is perpendicular to the axis of said spool, such that said clutch pins make point contact with said sloping guide surfaces, and such that said clutch pins are guided by said guide surfaces from said second upper edges to said first upper edges and then into said engaging recesses when said driving mechanism is operated in a direction for driving said spool.
