Claims

[Scope of utility model registration request]

The input gear and the reduction gear are interlocked and connected to the clutch shaft for 1st forward and forward speed, and the input gear and the speed increasing gear are interlocked and connected to the clutch shaft for 2nd forward and forward speed. Each of the front and reverse 1-speed transmission gears on the forward 1-speed clutch shaft side and the front and reverse 2-speed transmission gears on the forward and 2-speed clutch shaft side are directly meshed or connected to the transmission gear on the output shaft side. A transmission characterized in that each of the transmission gears on the other shaft side is interlocked and connected by meshing connection.
