1. A vacuum adiabatic body comprising:
a first plate to define a first portion of a wall;
a second plate to define a second portion of the wall;
a side frame to define another portion of the wall for an inner space, the another portion of the wall including a wall extending in a first direction corresponding to a height of the inner space,
wherein the side frame includes a first portion, a second portion and a third portion, the first portion of the side frame is spaced apart from the second portion of the side frame, and the third portion is disposed between the first portion of the side frame and the second portion of the side frame,
wherein each of the first plate, the second plate and the side frame are secured to form the inner space which is configured to be in a vacuum state,
wherein the vacuum adiabatic body provides a heat transfer path between the first plate and the second plate by passing along the side frame,
wherein the second portion of the side frame extends from a main portion of the vacuum adiabatic body toward a side portion of the vacuum adiabatic body,
wherein the first portion of the side frame and the third portion of the side frame contact with the inner space such that the first portion of the side frame and the third portion of the side frame are thermally insulated by the inner space,
wherein one end of the second portion of the side frame is spaced apart from an edge portion of the second plate in a second direction that extends from the main portion of the vacuum adiabatic body toward the side portion of the vacuum adiabatic body, and a space is provided between the one end of the second portion of the side frame and the edge portion of the second plate in the second direction that extends from the main portion of the vacuum adiabatic body toward the side portion of the vacuum adiabatic body, such that the heat transfer via the side frame toward the side portion of the vacuum adiabatic body can be reduce,
wherein the first portion of the side frame is spaced apart from a front portion of the vacuum adiabatic body, and the second portion of the side frame contacts the front portion of the vacuum adiabatic body, and
wherein the first portion of the side frame and the second portion of the side frame extend in opposite directions from both ends of the third portion of the side frame, respectively.
