ABSTRACT:
A transmission system includes transmission case having a work opening formed therein and configured to avoid the necessity for enlarging a transmission case, to prevent an increase in weight and to prevent and inhibit a reduction in the rigidity of the transmission case due to the presence of the work opening. The work opening provides a point of access to permit manual linking/unlinking of an operation cable to/from a derailleur, while ensuring easy oil lubrication for a chain through the work opening. The transmission system also comprises a sprocket cluster constituted of a plurality of transmission sprockets, and a derailleur. The work opening is formed in an axially directed case wall, which is located closest in the axis direction to a transmission sprocket having the largest outer diameter among the sprocket cluster. The same transmission sprocket is located closest in the radial direction to the work opening.
