Claims (1)

[Scope of utility model registration request] A wire for suspending equipment such as lighting equipment, a drum for winding the wire, and a drum that is swingably arranged to tilt in accordance with the inclination of the outer periphery of the wire wound around the drum and the rotational axis of the drum. The inclination detection member includes an arm connected to be rotatable around a fixed shaft disposed approximately parallel to the rotation axis of the drum and tiltable with respect to the fixed shaft, and an arm connected to the drum so as to be tiltable relative to the fixed shaft. a detector whose tip is provided protruding toward the drum and whose tip contacts the outer periphery of a wire wound around the drum, thereby tilting the arm relative to a fixed axis in accordance with the inclination of the outer periphery of the wire relative to the rotational axis of the drum; It consists of a slide shaft that is fixed at a fixed position on the arm so that it is approximately parallel to the rotation axis of the arm, and a slide roller that is supported so that it can slide freely in the axial direction of the slide shaft. A lifting device in which a wire is wound around a roller so that the detector is biased toward the center of rotation of the drum.
