A transmission with 6 forward steps and 1 backward step is provided to reduce the length of transmission by installing the 2 shift gear and the 3 shift gear in order to be geared in the input shaft. An input shaft(32) receiving the torque of the engine, and a top output axis(34) and a bottom output axis(36) are side by side arranged within a transmission housing(30). 1 shift driving gear(41), 2 shift driving gear(42), 5 shift driving gear(45), 4 shift driving gear(44) and 6 shift driving gear are successively fixed to the input shaft with respectively. A back gear interlocked with the 1 shift driving gear, 3 shift driven gear(54) interlocked with the 2 shift driving gear and 4 shift driven gear interlocked with the 4 shift driving gear are respectively rotatively freely set up in the top output axis.
