Handle mounting structure in fishing reel

A handle mounting structure in which a handle shaft is fittingly inserted into a through-hole of a cylindrical drive shaft longitudinally, and a threaded member is threadingly engaged with the handle shaft so that the handle shaft is fixed to the cylindrical drive shaft, said structure comprising:

• a first portion defining a first engaging surface of reduced diameter that circumscribes an axis of said handle shaft at an end thereof and advancing longitudinally when said threaded member and said handle shaft are contractingly threaded;
• and
• a second portion defining a second inclined smooth surface, said second inclined smooth surface being forcibly brought into pressure-contact with said first engaging surface when said threaded member and said handle shaft are contractingly threaded, said second portion being radially displaced with respect to said cylindrical drive shaft as a consequence of said pressure-contact, so that an outer periphery of said second portion is brought into pressure-contact with an inner periphery of said cylindrical drive shaft,
• wherein said handle shaft evinces a polygonal outer surface and said through-hole of said cylindrical drive shaft evinces a polygonal inner surface, said handle shaft being rotationally interconnected with said cylindrical drive shaft through a mating of said polygonal outer surface and said polygonal inner surface, and wherein said second portion projects longitudinally along only one planar surface of said polygonal inner surface.

A handle mounting structure in a fishing reel, comprising:

• a drive shaft having a drive gear and a through-hole defining a polygonal inner surface;
• a handle shaft to which a handle is fixed, said handle shaft evincing a polygonal cross section, said handle shaft being non-rotatably fitted into said through-hole of said drive shaft, wherein said polygonal cross section of said handle shaft matingly engages said polygonal inner surface of said through-hole provided in the drive shaft;
• at least one tapered engaging surface formed on an end portion of said handle shaft circumscribing an axis of said handle shaft;
• a threaded member threadingly engageable with said handle shaft;
• and
• a securing member disposed on said threaded member, said securing member having a securing portion inserted and engaged between said at least one tapered engaging surface and said polygonal inner surface of said through-hole of said drive shaft, wherein said securing member projects longitudinally along only one planar surface of said polygonal inner surface.
