PURPOSE: To secure flatness between a partition member and a door opening edge by providing a guide means which allows the partition member to pass over the neutral point of a spring and turns the partition member in a folding direction and in an opening direction.
CONSTITUTION: A partition member side guide 12 forms a slanted face guide part 12a, which turns a partition member 9 in an opening direction, and a locking part 12b, which holds a position of the partition member 9 when it is turned up to the substantially saw plane as a main body opening edge, as a guide face. When a door 6 is kept closing, the partition member 9 in a folded state is pushed out by a main body side guide pin 13 by that which corresponds to invasion of the slanted face guide part 12a, thus the partition member side guide 12 works to turn the partition member 9. In this case, the partition member 9 first resists the tension force of a tension spring 11; however, when it passes over the neutral point of the spring, the partition member 9 is tuned in an opening direction by the force of the tension spring 11. When the closing movement of the door 6 is completely finished, the main body side guide pin 13 is engaged with the locking part 12b of the slanted face guide part 12a, and the partition member 9 is fixed. Accordingly, flatness between the partition member and the door opening edge can be secured.
