PROBLEM TO BE SOLVED: To provide a transmission reducing a space occupied by a speed reduction mechanism and a speed increase mechanism and employed as a transmission for an automobile. SOLUTION: This transmission includes: two pairs of gear elements; two pairs of clutches releasably coupling an input shaft, an output shaft and the two pairs of gear elements; a pair of noncircular gear elements; a clutch for the pair of noncircular gear elements releasably coupling the pair of noncircular gear elements between the input shaft and the output shaft; the speed reduction mechanism coupling in a rotation transmittable manner the first portion of the input shaft with one gear element of the pair of gear elements arranged and the second portion of the input shaft with one noncircular gear element of the pair of noncircular gear elements arranged; and the speed increase mechanism coupling in the rotation transmittable manner the first portion of the output shaft with the other gear element of the pair of gear elements arranged and the second portion of the output shaft with the other noncircular gear element of the pair of noncircular gear elements arranged. The speed reduction mechanism and speed increase mechanism are respectively provided with a plurality of gear shafts, and the gear shaft of the speed reduction mechanism and the gear shaft of the speed increase mechanism are arranged on a common axis.
