    Abstract: A housing includes an air introduction flow passage, an air discharge flow passage, and a desiccant agent accommodated in the housing. One end portion of the housing is at a lower side of the housing in a vertical direction aligned with the axial direction. An air-liquid separation chamber is formed at a bottom portion of the housing, and includes an air supply passage supplying air to the desiccant agent at an upper housing surface, and is communicated with the air introduction flow passage and the air discharge flow passage to separate moisture in the air introduced from the air introduction flow passage. An adsorption member is accommodated in the air-liquid separation chamber to adsorb moisture separated in the air-liquid separation chamber. Air introduced from the air introduction flow passage is supplied to an air suspension device through the adsorption member and the desiccant agent.
