  "textContent": "A power transmission device is provided, which includes a main-drive-wheel drive part, and an auxiliary-drive-wheel drive part having a power extraction part which has a transfer gear set comprised of a transfer drive gear connected to the main-drive-wheel drive part and a transfer driven gear meshing with the transfer drive gear and configured to transmit power to the auxiliary drive wheels. In a power transmission path from the main-drive-wheel drive part to the transfer drive gear, an input shaft connected to the main-drive-wheel drive part and a power transmission shaft connected to the transfer drive gear are coupled to each other in a radial direction through a first spline having a first backlash. A first shear damper without backlash and a second shear damper provided with a second spline having a second backlash smaller than the first backlash are provided between the input shaft and the power transmission shaft.",
