PROBLEM TO BE SOLVED: To provide a transmission applied to a service vehicle having a driving source and a right-and-left pair of a first and a second crawler type running devices, in which the difference of a driving rotation number between a right-and-left pair of a first and a second output axes can be made large so that a spin turn can be expressed and the cost is reduced and the size is made small by the reduced parts count.SOLUTION: A transmission is provided with: a differential 23 capable of differentially transmitting a rotation power input from a gear case to a first and a second output shafts 22 (1), 22(2); and a speed increasing device 24 capable of transmitting the rotation power input from the gear case to the first and the second output shafts to increase the speed. The speed increasing device has a first and a second speed increase conduction paths 50 (1), 50 (2) capable of transmitting the rotation power of an input gear 41 of the differential to which the rotation power is differentially input from the gear case to the first and the second output shafts in a synchronous state to increase the speed, and a first and a second multiplate type clutches 51 (1), 51 (2) are respectively inserted into the first and second speed increase conduction paths. |
