Device for driving electrical current generator for use in motorcycle

A device for driving an electrical current generator for use in a motorcycle comprising:

• (a) an engine unit for housing an engine of said motorcycle;
• (b) said electrical current generator provided separately from and mounted outside of said engine unit;
• (c) power transmission means provided between one end of an output shaft of said engine and one end of a rotary shaft of said generator and comprising:
• a V-belt;
• a first pulley mounted on one of said one ends of said output shaft and said rotary shaft;
• and
• a second pulley mounted on the other of said one end, said second pulley including means for increasing a rotational speed ratio of said rotary shaft to said output shaft during low rotation range of said engine and decreasing said ratio during high rotation range thereof, said V-belt being mounted between said first pulley and said second pulley, said engine unit and said electrical current generator being provided at the same side of said power transmission means;
• said power transmission means further comprising;
• an endless transmission member;
• a planetary gear and clutch mechanism connected to said one end of said output shaft;
• a first pulley mounted on said planetary gear and clutch mechanism, and
• a second pulley mounted on said one end of said rotary shaft, said V-belt being mounted between said first and second pulleys;
• and
• (d) covering means providing a confined space outside of said engine unit for housing said power transmission means within said confined space separate from said electric current generator.
