PROBLEM TO BE SOLVED: To obtain a sagger adapted to avoid the increase of a crack generated at the opening of the sagger by making it possible to prevent the displacement of the saggers even when they are stacked, and enclosing the protrusion of the sagger of the lower stage by the recess formed at the bottom of the sagger of the upper stage of the bowl even if the crack is generated at the opening of the sagger. SOLUTION: A recess 3 formed due to the downward protrusion of the part of the thickness of a frame body 2 is provided on the outer periphery of the bottom of the body 2 of the sagger 1, and a protrusion 4 formed due to the upward protrusion of the part of the thickness of the body 2 is provided on the upper inner periphery of the body 2. When the sagger 1 are stacked, the protrusion 4 of the bowl upper part 5 of the lower stage is engaged with the recess 3 of the upper part of the sagger 1 directly above it to enclose the protrusion 4 of the sagger of the lower stage with the recess 3 of the sagger 1 of the upper stage. |
