170 and 180 are made of a brush material as described above, the following effects are obtained: it is possible to prevent the occurrence of dust due to friction and abrasion that may occur when a conventional general sealing member made of a synthetic resin material such as rubber is used, and thus not only to prevent the dehumidification rotor 100 from being contaminated and indoor air from being contaminated due to the contamination, but also to reduce the friction at the contact surfaces of the first and

second cases

150 and 160, the rotor 110, the first and second rotor cases 140-1 and 140-2, which are in contact with the air

leakage prevention members

6. A dehumidifying rotor as claimed in claim 3,

the first and second rotor housings are assembled with each other at the following positions: the first protrusion formed at the first rotor case corresponds to the second protrusion formed at the second rotor case, and the second protrusion formed at the first rotor case corresponds to the first protrusion formed at the second rotor case.

7. A dehumidifying rotor as claimed in claim 3,

a gear part having a gear coupled to a motor gear coupled to a rotating shaft of a motor that provides a driving force for rotating the rotor is integrally formed on an outer circumferential surface of the rotor case body.

8. The desiccant rotor of claim 1,

a core for receiving a rotating shaft constituting a rotation center of the rotor at an inner side is provided at a center of the rotor,

a plurality of insertion grooves formed at both side portions of the core at a predetermined interval in a circumferential direction, the plurality of insertion grooves being formed at a predetermined depth in a front-rear direction,

the pair of rotor housings includes:

a rotor housing main body configured in a circular shape;

a hub provided at the center of the inside of the rotor case main body; and

and a plurality of spokes having both ends supported by the rotor housing body and the hub, inserted into and coupled to the insertion grooves of the core, and arranged in a radial shape.

9. The desiccant rotor of claim 1 further comprising:

a housing in which the first space and the second space are formed, a frame that partitions the first space and the second space is provided, and the housing accommodates the rotor;

a first air leakage preventing member for preventing air leakage in a side direction between the rotor and the housing; and

a second air leakage preventing member for preventing air leakage in a circumferential direction between the rotor and the housing.

10. The desiccant rotor of claim 9,

the pair of rotor housings are configured by a first rotor housing provided on one side surface of the rotor and a second rotor housing provided on the other side surface of the rotor and assembled to the first rotor housing,

the casing is composed of a first casing provided on one side of the first rotor casing and a second casing provided on the other side of the second rotor casing and coupled to the first casing.

11. The desiccant rotor of claim 10,

the first leakage preventing member is doubly provided in a longitudinal direction between the first frame of the first casing and one side surface of the rotor and between the second frame of the second casing and the other side surface of the rotor at positions spaced apart from each other on both sides,
