Abstract
In a three-shaft type automatic transmission, a fifth frictionally engaging element is mounted on a second central shaft, and first and second frictionally engaging elements and third and fourth frictionally engaging elements are mounted respectively on first and third shafts which are disposed on opposite sides of the second shaft. When one of the first and third shafts is used as an input shaft, the second shaft is an output shaft. When one of the first and third shafts is used as an output shaft, the second shaft is an input shaft. The first and second frictionally engaging elements and the third and fourth frictionally engaging elements on the opposite sides of the second shaft are symmetrically disposed to reduce dead space and make the transmission case small. Because the positional relationship between the input and output shafts can be transposed, the property of the transmission for general purpose is enhanced.
