PROBLEM TO BE SOLVED: To provide a power transmission device, a power reception device and a non-contact power supply system, which are able to restrict a decrease in power supply efficiency while preventing damage to the power reception device and the power transmission device.SOLUTION: A platform 20 for non-contact power supply using a pair 5 of coils oppositely provided between a submerged mobile 10 and itself, which are movable relative to each other, comprises: a recessed part 30 that is able to be accommodated by making a space in at least part of the submerged mobile 10; a coil 21 forming a first pair 5A of coils that can be made opposite to each other on one of opposing wall parts 31 of the recessed part 30; and coils 21 forming a second pair 5B of coils that can be made opposite to each other on the other of the opposing wall parts 31 of the recessed part 30.
【課題】受電装置と送電装置の損傷を防止しつつ、給電効率の低下を抑制できる送電装置、受電装置及び非接触給電システムの提供。【解決手段】相対的に移動可能な関係を有する水中移動体10との間において、対向可能に設けられたコイル対5を用いた非接触給電を行うプラットフォーム20であって、水中移動体10の少なくとも一部を隙間をあけて収容可能な凹部30と、凹部30の向かい合う壁部31の一方側において対向可能な第1のコイル対5Aを形成するコイル21と、凹部30の向かい合う壁部31の他方側において対向可能な第2のコイル対5Bを形成するコイル21と、を有する、という構成を採用する。【選択図】図1
