First claim
Opening claim text (preview).
The invention claimed is: 1 . A device comprising: a motor; an inverter configured to drive the motor; a gear device connected downstream of the motor; and a drive shaft configured to transmit, to a drive wheel, power of the motor transmitted from the gear device, wherein the drive shaft includes a portion to which a sheet-shaped noise reducing material is directly attached, the drive shaft includes a universal joint, and the sheet-shaped noise reducing material is directly attached to the universal joint. 2 . The device according to claim 1 , wherein the drive shaft includes a first drive shaft and a second drive shaft, and both of the first drive shaft and the second drive shaft are provided with the portion to which the sheet-shaped noise reducing material is directly attached. 3 . The device according to claim 1 , further comprising: a case accommodating the gear device, wherein the drive shaft includes a first region that is connected to the gear device inside the case, and a second region that is connected to the drive wheel outside the case, and the portion to which the sheet-shaped noise reducing material is directly attached is provided in the second region. 4 . The device according to claim 1 , wherein the sheet-shaped noise reducing material is directly attached to the drive shaft by an adhesive. 5 . The device according to claim 1 , wherein the sheet-shaped noise reducing material is directly attached to the entire circumference of the drive shaft.
