PROBLEM TO BE SOLVED: To attain a structure capable of supplying power to a sensor installed on a wheel according to power consumption, and further easily installing a non-contact transmission device having a size necessary for the supply of power.SOLUTION: In the vicinity of a differential side constant velocity joint 1 and a differential gear 24, a non-contact transmission device 4 capable of transmitting power and a signal in a non-contact manner is installed. A power wire 42 and a signal wire 43, which are connected to the non-contact transmission device 4, are inserted in an axial direction onto a radial inside of the differential side constant velocity joint 1, a radial inside of a transmission shaft 2 and a radial inside of a wheel side constant velocity joint 3. Then, the power wire 42 and the signal wire 43 are connected to a sensor installed on a wheel.SELECTED DRAWING: Figure 1
【課題】車輪に設置されたセンサに対し、消費電力に見合う大きさの電力を供給する事ができ、しかも、その為に必要なサイズの非接触伝送装置の設置を容易に行える構造を実現する。【解決手段】デフ側等速ジョイント1及びデファレンシャルギヤ24の周辺部に、電力及び信号を非接触に伝送可能な非接触伝送装置4を設置する。非接触伝送装置4に接続した電力用配線42及び信号用配線43を、デフ側等速ジョイント1の径方向内側と、伝達軸2の径方向内側と、車輪側等速ジョイント3の径方向内側とに、軸方向に挿通する。そして、これら電力用配線42及び信号用配線43を、車輪に設置したセンサに接続する。【選択図】図1
