To provide a housing auxiliary device capable of easily performing taking in and out of an article to be housed in relation to a housing part on the upper side with slight force.

The lower ends of a pair of parallel links 14, 15 are connected to a fixed bracket 13 fixed on the floor surface 11 in a closet 10 by pins 16, 17. A rising and lowering bracket 23 is connected to the upper ends of the parallel links 14, 15 by pins 21, 22, and a link mechanism 20 to be taken as a parallel movement mechanism is constituted. A slide table 27 is movably attached to the rising and lowering bracket 23. A tension coil spring 25 for elastically energizing the parallel links 14, 15 into the erecting state against the weight of a futon F is attached between the pins 16, 22 on the diagonal line of the link mechanism 20. When the futon F is taken out from the closet 10, the slide table 27 is horizontally drawn from a rack plate 26, and the futon F is taken out from the closet 10 while making the parallel links 14, 15 to fall to this side. At this time, the weight of the futon F is reduced by the tension coil spring 25, and taking-out is easily performed.
