An elevating body derailment detection device includes a wire, a suspension member, a detection circuit, an arm, and a detection unit. The wire is arranged in parallel with an elevating direction. The suspension member is provided at one end of the wire, and is provided with the first conductive part. The detection circuit includes second conductive parts to be electrically connected to the first conductive part. In the detection circuit, a current flows via the first conductive part. The arm is provided to an elevating body, and has a hollow portion through which the wire is to be passed in parallel with the elevating direction. When the elevating body is disengaged from the guide rail, the hollow portion contacts the wire to move the suspension member so that the first conductive part is electrically disconnected from the second conductive parts, and then the detection unit detects a derailment.
