A transfer device of a vehicle is provided, in which an auxiliary-drive-wheel output shaft extending in parallel with a main-drive-wheel output shaft is connected to a propeller shaft having a universal joint. An end part of the auxiliary-drive-wheel output shaft on a propeller shaft side is formed in a hollow shape and includes a fitting part configured to be spline-engaged with a joint part provided to the universal joint. The joint part is provided with a centering part which is inserted into a centering hole formed in a flange part provided to one side of the auxiliary-drive-wheel output shaft so that the joint part is centered on the auxiliary-drive-wheel output shaft. The flange part is sandwiched between a spacer and the joint part, and a bolt member is attached to a bolt hole formed in the centering part so that the propeller shaft is assembled to the auxiliary-drive-wheel output shaft.

A transfer includes: an input shaft; an output shaft; a high-low switching mechanism; an output member whose output destination is different from output destination of the output shaft; a clutch for transmitting a power to the output member; a first transmitting mechanism for transmitting movement of an internally threaded member to the clutch; and a drum cam having a cam groove. The cam groove includes a first inclined section that causes the high-low switching mechanism to be switched between a high-speed gear stage and a low-speed gear stage, and a second inclined section that causes the first transmitting mechanism to be switched between (i) a separated position in which the first transmitting mechanism is separated from the clutch and (ii) a contact position in which the first transmitting mechanism is in contact with the clutch, while the high-speed gear stage is established in the high-low switching mechanism.

A transfer device of a vehicle is provided, which includes an input shaft for receiving an output torque of a drive source at an axial first side, a main-wheel output part provided on a second side and for outputting the output torque to main drive wheels, an auxiliary-wheel output shaft provided in parallel to the input shaft and for outputting the output torque to auxiliary drive wheels, a coupling provided on the input shaft and for extracting a part of the output torque, a drive member having a hollow section and provided on the input shaft, a driven member provided on the auxiliary-wheel output shaft and meshed with the drive member, a universal joint provided on the auxiliary-wheel output shaft, and a damper device provided on the input shaft or the auxiliary-wheel output shaft and for reducing noise that occurs due to a variation of the output torque.
