To effectively use a narrow space in a Japanese house for drying laundry by effectively using an outer peripheral frame of an openable/closable laundry drying rack, which has not been conventionally used, and drying much laundry at the same time.

Openable/closable laundry drying racks are so constructed as to be vertically stacked, thereby effectively using an upper space. In addition, hanger hooks are attached to the outer periphery, which has not been used, of a relatively large laundry drying rack. Furthermore, means such as mounting of a rack provided with clothespins is applied, thereby providing such a structure as to enable drying of much laundry at the same time.
