ABSTRACT:
A mesh-type automatic transmission includes a power input shaft for introducing power of an engine, a plurality of transmission gears, a plurality of cogged clutches, a power output shaft for outputting driving force, a counter shaft, and a plurality of counter gears, for transmitting power of the engine to the power output shaft by rotating the power input shaft with the power of the engine, rotating the counter shaft, and transmitting rotation of the counter shaft to the power output shaft with automatic gear change by engaging and disengaging the cogged clutches to one of the transmission gears corresponding to the speed. The counter shaft is provided with an assist mechanism for transmitting rotational force of the power input shaft to the power output shaft by transmitting rotation of the counter shaft via the assist gear, during the period of disengagement of a gear to the engagement of a new gear during gear change.
