The distance between the left and right body 110 is preferably set to a suitable distance within 2 meters in consideration of the weight of the laundry, but may be a distance of 2 meters or more in the case of mainly hanging clothes such as futons. Since the laundry drying rack 100 according to the present invention has two separate bodies 110, its weight is lighter than that of the one-piece type, and can be easily mounted on the ceiling by itself, and the left and right space intervals can be adjusted according to the use of the building and the space. .

In the present invention, each of the left and right body 110 is provided with a motor (230 of FIG. 2) to drive each of the left and right chains 120 separately with two motors. That is, the structure is simpler than the method of driving both the left and right wires with one motor in the separate body type laundry dryer, and the principle of operation can be simplified. Since the left and right frames 140 through which the plurality of drying rods 150 through which laundry is passed are preferably horizontal, it is preferable that each of the motors 230 of FIG. 2 be driven at the same time.

The left and right chains 120 are vertically driven by the driving of the motor 230 (see FIG. 2).

The left and right bellows 130 are coupled to each of the left and right chains 120 and contracted and expanded by the vertical driving of the left and right chains 120. When the left and right chains 120 are wound, the left and right bellows 130 are expanded, and when the left and right chains 120 are unwound, the left and right bellows 130 are contracted.

The left and right frames 140 are coupled to the ends of each of the left and right bellows portions 130, and a plurality of holes 145 are provided to allow the plurality of drying rods 150 to pass therethrough.
