Abstract
The vacuum iadiabatic body of this embodiment may include a first plate, a second plate, a seal configured to seal the first plate and the second plate to provide a vacuum space, and a support configured to maintain the vacuum space. Optionally, the support may include a first support having a first support plate formed in a grid shape and a plurality of first spacer coupling portions protruding from the first support plate. Optionally, the support may include a second support having a second support plate formed in a grid shape and a plurality of spacers protruding from the second support plate and coupled to each of the plurality of spacer coupling portions to form a plurality of bars together with the plurality of spacer coupling portions. Optionally, the support may include a radiation resistance sheet supported by some of the plurality of bars and spaced apart from at least one of the first support plate and the second support plate. Optionally, a spacer of a support bar supporting the radiation resistance sheet of the plurality of bars may include a second portion extending from the second support plate, a first portion extending from the second portion and having a diameter smaller than a diameter of the second portion, and a stepped portion provided between the first portion and the second portion. Optionally, one surface of the radiation resistance sheet may be seated on the stepped portion, and the other surface of the radiation resistance sheet may be in contact with a spacer coupling portion coupled to the spacer of the support bar.
