OG exemplary drawing
 
1. A vacuum adiabatic body, comprising:
a first plate;
a second plate;
a vacuum space provided between the first plate and the second plate; and
a support configured to maintain a distance between the first plate and second plate; and
a radiation resistance sheet to reduce heat radiation between the first plate and second plate, wherein the support includes at least one bar that extends in a direction between the first plate and second plate, a first support plate that extends in a direction in which the first plate extends and a second support plate that extends in a direction in which the second plate extends, and wherein the at least one bar includes:
a first portion that extends from the first support plate; and
a second portion that extends from the second support plate and is coupled to the first portion, and wherein a length of the first portion protruding from the first support plate is greater than a length of the second portion protruding from the second support plate.
 
18. A vacuum adiabatic body, comprising:
a first plate;
a second plate;
a vacuum space provided between the first plate and the second plate;
a support configured to maintain a distance between the first plate and second plate; and
a radiation resistance sheet to reduce heat radiation between the first plate and second plate, wherein the support includes at least one bar that extends in a first direction between the first plate and second plate, and wherein the at least one bar includes:
a first portion that extends in the first direction which is different from a second direction in which the first plate extends; and
a second portion provided as a component separate from the first portion and including a column having an accommodation portion in which the first portion is supported, wherein the second portion includes an inner circumferential surface having a first part that contacts the first portion and a second part spaced apart from the first portion.
