Transmission for vehicle

The transmission for a vehicle comprising

• a main shaft to which the rotation of a crankshaft is transmitted,
• a counter shaft disposed in parallel to said main shaft,
• a plurality of gear trains interposed between said main shaft and said counter shaft,
• a shift mechanism for connecting both the shafts by any of the gear trains for establishing a desired shift stage, and
• a synchro mechanism for synchronizing the speed of rotation of both said shafts when said shift stage is established,
• said main shaft and said counter shaft being disposed perpendicular to an axis of said crankshaft, wherein said synchro mechanism is provided on said counter shaft.
