Support devices, suspension devices and buildings

Abstract

The present invention provides a support device, a suspension device, and a building that facilitate the attachment and removal of a suspension device to the ceiling, for which electrical equipment supplied with electricity is attached. [Solution] The support device 20 removably supports the suspension device 50 to the ceiling 2. The support device 20 includes a support part 21 that supports the suspension device 50, a first power line 22, a second power line 23, a first electrode 24 connected to the first power line 22, and a second electrode 25 connected to the second power line 23. The support part 21 has a support part body 31 that is attached to the ceiling 2, and a receiving part 32 that contacts the suspension device 50 to receive the load of the suspension device 50. The first electrode 24 is provided on a receiving surface 33 of the receiving part 32 that faces upward to receive the load of the suspension device 50. The second electrode 25 is provided on the support part 21 at a position away from the receiving surface 33.
