PROBLEM TO BE SOLVED: To provide a non-contact power supply device for an electric two wheeler or an electric three wheeler that can perform stably non-contact power supply to an electric two wheeler just by locking the two wheeler to a stand in a parking lot.SOLUTION: A parking stand for a two wheeler has a locking mechanism and a power feeding coil 73, and the electric two wheeler has a locked portion and a power receiving coil 65. The power feeding coil 73 comprises a core, of which cross section is formed in a channel shape, which has an opening surface orthogonal to a movement direction of the electric two wheeler moving to a position where the wheeler is locked by the locking mechanism and an opening surface opposing to the electric two wheeler. When the electric two wheeler reaches the position where the electric two wheeler is locked, the power receiving coil gets into the core in the channel shape of the power feeding coil. Since the power feeding coil and the power receiving coil are provided near the locking mechanism and the locked portion, when the locking mechanism is connected to the locked portion, positions of the power feeding coil and the power receiving coil are regulated and kept so as not to positionally deviate, which enables power supply having high power supply efficiency.
【課題】電動二輪車を駐輪場のスタンドに施錠するだけで安定した非接触給電が行われる電動二輪・三輪車用非接触給電装置を提供する。【解決手段】駐輪スタンドは施錠機構と送電コイル73とを有し、電動二輪車は被施錠部と受電コイル65とを有する。送電コイル73は、施錠機構で施錠される位置に移動する電動二輪車の移動方向に直交する開放面と、電動二輪車と対向する開放面とを有する断面コ字状のコアを備え、電動二輪車が施錠される位置に達すると、受電コイルが送電コイルのコ字状コア内に入り込む。送電コイル及び受電コイルは、施錠機構及び被施錠部の近傍に在るため、施錠により施錠機構と被施錠部とが結合すると、送電コイル及び受電コイルの位置が規制されて位置ずれの無い状態に保たれ、給電効率の高い給電が行われる。【選択図】図5
