ABSTRACT:
A gear crank apparatus for a bicycle for supporting a plurality of chainwheels. This apparatus includes a boss secured to an end of a crank axle, a chainwheel supporting member extending radially outwardly from the boss for supporting the chainwheels axially spaced apart from one another, and a crank.
The crank includes a first crank portion extending radially outwardly from the boss and inclined axially outwardly away from a side face of an adjacent chainwheel supported by the chainwheel supporting member to a position adjacent an outer periphery of the adjacent chainwheel, and a second crank portion extending from the first crank portion in a direction substantially perpendicular to the axis.
The chainwheel supporting member extends from the boss as inclined axially inwardly away from the crank and includes chainwheel mounting surfaces formed in peripheral regions thereof and extending perpendicular to the axis for attaching the chainwheels.
