Claims

[Scope of utility model registration request]

A hydraulic torque converter includes an input rotating member and an output rotating member configured to rotate around the same axis, and an input shaft and an output shaft coexisting on the same axis as the rotating axis of the output rotating member. a planetary gear type transmission that drive-connects the input shaft to the output rotating member and selectively achieves a plurality of gears according to engagement switching of a frictional engagement device; and a planetary gear type transmission that is arranged parallel to the output shaft. a counter shaft, a power transmission device that transmits the rotational power of the output shaft to the countershaft, a differential gear device that transmits the rotational power of the countershaft to the front wheel axle, and a rear wheel provided coaxially with the output shaft. An automatic transmission for four-wheel drive, comprising a rear axle drive shaft that transmits rotational power to an axle, and a clutch that selectively drives and connects the output shaft and the rear axle drive shaft.
