To provide a structure capable of efficiently cooling a power transmission apparatus and a power reception apparatus that have coils arranged to be laminated.SOLUTION: A power reception apparatus 30 of a non-contact power feeding system 10 that feeds power in a non-contact manner, comprises: a plurality of power reception coils 36u, 36v and 36w; and a housing H that accommodates the plurality of power reception coils 36u, 36v and 36w. The housing H has a cooling main body part 42 and a cover 50 that covers the power reception coils 36u, 36v and 36w. Each power reception coil 36u, 36v, 36w is provided with a cover opposed part 36d opposed to an inner face 50a of the cover 50 without interposing the other power reception coils 36u, 36v, 36w. The inner face 50a of the cover 50 is formed with an uneven configuration. A recessed part 52 recessed toward the power reception coils 36u, 36v and 36w is provided on an outer face 50d of the cover 50 at a position overlapped with the cover opposed part 36d of each power reception coil 36u, 36v, 36w in a lamination direction.SELECTED DRAWING: Figure 2

    【課題】積層配置されたコイルを有する送電機器及び受電機器を効率的に冷却する構造を提供することにある。【解決手段】非接触で給電を行う非接触給電システム10の受電機器30において、複数の受電コイル36u,36v,36wと、複数の受電コイル36u,36v,36wを収容する筐体Hと、を備え、筐体Hは、冷却本体部42と、受電コイル36u,36v,36wを覆うカバー50とを有し、各受電コイル36u,36v,36wには、他の受電コイル36u,36v,36wを介在させることなくカバー50の内面50aに対して対向するカバー対向部36dがそれぞれ設けられており、カバー50の内面50aには、凹凸形状が形成されており、カバー50の外面50dには、積層方向において各受電コイル36u,36v,36wのカバー対向部36dに重複する位置に、受電コイル36u,36v,36w側に凹む凹部52が設けられている。【選択図】 図2
