Abstract: The present disclosure provides an expansion valve device which is capable of being mounted easily. The expansion valve device includes: an expansion valve body that depressurizes refrigerant; and a casing in which the expansion valve body is housed. The casing includes a tube portion having an opening through which the expansion valve body is able to pass. The tube portion is formed integrally to surround over an entire perimeter of the expansion valve body. The tube portion has: an elastic holding portion formed of an elastic material and holding the expansion valve body by a reaction force due to elastic deformation by surrounding the entire perimeter of the expansion valve body; and a support portion formed of a material having a higher rigidity than the elastic holding portion and supporting the elastic holding portion. At least a part of the support portion is exposed to outside of the casing.
