PROBLEM TO BE SOLVED: To provide a non-contact power supply device and a frame crack detection method, capable of detecting a crack on a frame at an earlier stage.SOLUTION: A non-contact power supply device 100 includes a power transmission coil 12 and transmits power to a power reception coil 22 provided on the vehicle 200 side by using magnetic coupling with the power reception coil 22 in a non-contact manner. The non-contact power supply device 100 comprises: a ground side coil frame 102 for accommodating the power transmission coil 12; a pump P for performing gas transfer operation of transmitting a gas into the ground side coil frame 102 or extracting a gas from the inside of the ground side coil frame 102; a pressure sensor 16 for detecting pressure inside the ground side coil frame 102; and a crack detection unit 15a for determining whether or not a crack exists on the ground side coil frame 102 from a variation in pressure detected by the pressure sensor 16 after gas transfer by the pump P.SELECTED DRAWING: Figure 1
【課題】より早期に筐体の割れを検出することが可能な非接触給電装置及び筐体割れ検出方法を提供する。【解決手段】非接触給電装置100は、送電コイル12を有し、車両200側に設けられた受電コイル22と磁気的結合により受電コイル22に対して非接触で送電するものであって、送電コイル12を収納する地上側コイル筐体102と、地上側コイル筐体102内に気体を送り込み又は地上側コイル筐体102内から気体を引き抜く気体の移送動作を行うポンプPと、地上側コイル筐体102内の圧力を検出する圧力センサ16と、ポンプPによる気体移送後において圧力センサ16により検出される圧力の変化から、地上側コイル筐体102に割れが発生しているかを判断する割れ検出部15aと、を備える。【選択図】図1
