To provide an unmanned movable body which inhibits eddy current from occurring in a top plate.SOLUTION: An unmanned movable body 20 includes: a power storage part to which electric power is supplied by non-contact power supply and which supplies electric power to a motor; a power reception device 60 having a power reception coil 61 electrically connected to the power storage part; an unmanned movable body control unit which controls the unmanned movable body; a housing 20a which houses the power storage part and the unmanned movable body control unit; a metallic top plate 22 disposed at the vertical upper side of the housing; and a magnetic flux shield member 23 which is attached to the housing and shields magnetic flux. At least the power storage part and the unmanned movable body control unit are electrically connected to form a circuit part. The power reception device is disposed at one side of the housing in a first direction perpendicular to a vertical direction. The magnetic flux shield member is disposed between the power reception coil and the circuit part when viewed in the first direction, extends from a position below the top plate to a position above the top plate at an area closer to one side as seen in a lateral direction than the top plate, and inhibits magnetic flux discharged from a power transmission device to the power reception device from reaching the top plate.SELECTED DRAWING: Figure 5
【課題】天板に渦電流が生じることを抑制する無人移動体を提供する。【解決手段】無人移動体20は、非接触給電によって電力が供給され、モータに電力を供給する蓄電部と、蓄電部と電気的に接続される受電コイル61を有する受電装置60と、無人移動体を制御する無人移動体制御ユニットと、蓄電部および無人移動体制御ユニットを収容する筐体20aと、筐体の鉛直方向上側に配置される金属製の天板22と、筐体に取り付けられ磁束を遮蔽する磁束遮蔽部材23を備える。少なくとも蓄電部と無人移動体制御ユニットは電気的に接続され、回路部を構成する。受電装置は、鉛直方向と直交する第1方向において筐体の一方側に配置される。磁束遮蔽部材は、受電コイルと回路部との第1方向の間に配置され天板よりも左右方向一方側において、天板よりも下側から天板よりも上側まで延び、送電装置から受電装置に放出された磁束が天板に到達することを抑制する。【選択図】図5
