PROBLEM TO BE SOLVED: To prevent an external stress from being propagated to a sensor that is installed within a coil unit in the case where the stress is applied, while securing load resistance of the coil unit.SOLUTION: The present invention relates to a coil unit that is provided at a ground side. The coil unit comprises: a coil; at least one sensor for detecting an object that is present above or around the coil unit; and a housing in which the coil and the sensor are accommodated. In the coil unit, the housing includes a partition plates for separating the housing into a coil space in which the coil is accommodated, and a sensor space which is positioned vertically higher than the coil space and in which the sensor is accommodated; and at least one strut for holding an internal space of the sensor space. The sensor is disposed on the partition plate without being brought into contact with an upper internal surface part of the housing.SELECTED DRAWING: Figure 3
【課題】コイルユニットの耐荷重性を確保しつつ、外部応力が加わった際にコイルユニット内部に設置されるセンサへ応力が伝わることを抑制すること。【解決手段】地上側に設けられるコイルユニットであって、コイルと、コイルユニットの上方又は周囲に存在する物体を検知する少なくとも1つのセンサと、コイル及びセンサを収容する筐体と、を備え、筐体は、コイルを収容するコイル用スペースとコイル用スペースよりも鉛直上方に位置しセンサを収容するセンサ用スペースとに仕切る仕切り板と、センサ用スペースの内部空間を保持する少なくとも1つの支柱と、を有し、センサは、センサ用スペースにおいて、仕切り板上に筐体の上方内面部とは非接触で配置されているコイルユニット。【選択図】図3
