  The adsorbing member 21 is composed of a porous body and has high adsorbability with respect to moisture. The adsorption member 21 is formed in a circular shape, and is attached to the flow path forming member 24 so as to be rotatable. A tooth portion (not shown) is provided at the outer peripheral end of the suction member 21, and a gear (not shown) that meshes with the tooth portion is rotated by the motor 26, whereby the suction member 21 rotates.

  The circulation fan 22 is attached to the upper part of the flow path forming member 24 so as to protrude rearward. The heater 23 is disposed on the rear side of the adsorption member 21. The heater 23 has a substantially fan shape and is attached to the flow path forming member 24 so as to cover a part (approximately 1/6) of the rear surface of the adsorption member 21.

  The flow path forming member 24 is made of resin, and includes a first flow path 24a, a second flow path 24b, a condensing unit 25, and a third flow path 24c. Air circulates in the order of the circulation fan 22, the first flow path 24a, the heater 23, the second flow path 24b, the condensing unit 25, and the third flow path 24c. This circulating air is called regeneration air.
