Abstract
A lock member L composed of one operation portion La biased by an inclined spring member 12 and paired lock bars Lb is attached to each of side walls 3 to be brought down firstly. A driven pin 15 formed on an operation portion is inserted through an inclined cam groove 21a of each of the lock bars. The lock member is attached to the side wall to be brought down firstly by fitting a pivotal shaft 11b formed on the operation portion into a fitting recess portion 3j1 of a pivotal shaft support block 3j formed on the side wall to be brought down firstly. Thus, at whichever position on the operation portion the operator' finger are laid, the lateral paired lock bars disposed opposite each other across the operation portion are moved in the horizontal direction by the same amount. Consequently, the lock state established between the short side wall and the long side wall via the lock member can be reliably cancelled.
