<p>PROBLEM TO BE SOLVED: To prevent a door body from becoming unopenable due to deformation.SOLUTION: A rod 13a in a door body 10 integrally has a base shaft part 13a1 and a head part 13a2 thicker than the base shaft part 13a1, and a receiving member 20 on an immovable portion side has an insertion and release hole 22a1 through which the head part 13a2 can be loosely inserted to penetrate therethrough, and a guide hole 22a2 continuously extended from the insertion and release hole 22a1 to a release direction and having a size in which the head part 13a2 cannot be inserted and the base shaft part 13a1 can be loosely inserted, and first gaps X1 and X2 between the insertion and release hole 22a1 and the head part 13a2 are set to be larger than second gaps Y1 and Y2 in a direction orthogonal to a door body opening and closing direction between the insertion and release hole 22a1 and the head part 13a2.</p> |
