To easily take in and out an article of one of housing shelf of a pair of left and right shelves by moving another housing shelf in the longitudinal direction, and also forming it so as to be rotatable by a hinge mechanism, and forming the another housing shelf so as to go in and out of a space part of the one housing shelf through a connecting tool at that time.
In a pair of left and right housing shelves 2 and 3, a rail mechanism 4 is arranged in response to one side part of one housing shelf 3, and is made movable in the longitudinal direction, and is rotated up to a right angle with a shaft pin 5a as a rotary shaft in the opposite direction of another housing shelf 2 through a hinge mechanism 5 in a condition of being pulled out forward. The another housing shelf 2 is towed on the rail mechanism 7 through a connecting tool 6 when the one housing shelf 3 rotates, and moves up to a space part of the one housing shelf. In this case, since an engaging fitting part 6b of the connecting tool 6 engages with an engaging projection part 3c of the housing shelf 2, the housing shelf 2 can be smoothly towed. The housing shelf 3 is smoothly moved to a former position by energizing force of a spring 6a.
