A rotor and a sealing device for a rotary adsorber is disclosed. The rotor includes a rim, spokes, arc-shaped sectors, a calking material, and a thermal insulating seal. The spokes divides the rim into arc-shaped portions. The sectors are disposed in the rim and include a gas adsorptive element. The calking material is provided between each sector and one of the rim and the spoke. The thermal insulating seal covers end surfaces of the spokes and joint portions of the sectors. The sealing device includes a sealing material, a mounting plate, a connecting portion, a rod member, and a spring. The sealing material is slidably interposed between a partitioning frame of the rotary adsorber and the mounting plate. The connecting portion fixes the mounting plate to the partitioning frame. The rod member is fixed to the connecting portion. The spring is interposed between the sealing material and the connecting portion.
