Wireless power transfer system and vehicle electric power supply device

A wireless power transfer system that supplies electric power to an object in which an electric power supply secondary coil capable of receiving wireless power transfer is incorporated, the wireless power transfer system comprising:

• an electric power supply apparatus having an electric power supply primary coil capable of supplying electric power to the electric power supply secondary coil in a wireless manner, and a drive circuit that drives the electric power supply primary coil;
• and
• a posture/position adjustment mechanism capable of adjusting a posture or position of the electric power supply primary coil, wherein
• the wireless power transfer system obtains, by means of data transfer, specific coil position information that is coil position information corresponding to information related to a position of the electric power supply secondary coil in a specific object that is an object that has made an electric power supply request, and
• electric power is supplied in a wireless manner from the electric power supply primary coil to the electric power supply secondary coil after the posture/position adjustment mechanism adjusts the posture or position of the electric power supply primary coil based on the information related to the position of the electric power supply secondary coil in the specific object corresponding to the specific coil position information.

A wireless power transfer system that supplies electric power to an object in which an electric power supply secondary coil capable of receiving wireless power transfer is incorporated, the wireless power transfer system comprising:

• an object support structure that is a structure capable of supporting the object;
