PROBLEM TO BE SOLVED: To provide an expansion valve device showing an improved installing characteristic and assembling characteristic.SOLUTION: An expansion valve device 1 comprises an expansion valve main body 2 acting as a pressure reducing device at a freezing cycle of a vehicle and a case part 3 for storing the expansion valve main body 2, The case part 3 has a cylindrical housing part 4 for storing the expansion valve main body 2 in it and holding it and a cover part 5 fitted to the housing part 4. The housing part 4 is a cylinder and has a cylindrical part 41 extending in a direction from one of the two connection surfaces to the other at the expansion valve main body 2, and a bottom part 42 arranged at an end part of the evaporator connecting surface 26 of the cylindrical part 41 and formed with an opening. The cylindrical part 41 is integrally formed over an entire periphery enclosing the expansion valve main body 2. The cylindrical part 41 has an elastic holding part 412 formed by soft material holding the stored expansion valve main body 2 and a supporting part 411 formed by hard material having at least a part of it exposed outside.SELECTED DRAWING: Figure 3

    【課題】装着性および組付性が向上された膨張弁装置を提供する。【解決手段】膨張弁装置1は、車両の冷凍サイクルにおいて減圧装置として機能する膨張弁本体2と、膨張弁本体2を収容するケース部3とを備える。ケース部3は、膨張弁本体2を内部に収容して保持する筒状体であるハウジング部4と、ハウジング部4と嵌合するカバー部5とを有する。ハウジング部4は、膨張弁本体2における2つの接続面の一方から他方へと向かう方向に延びる筒状部41と、筒状部41の蒸発器接続面26側の端部に設けられた、開口が形成された底部42とを有する筒状体である。筒状部41は、膨張弁本体2を取り囲む全周にわたって一体である。筒状部41は、収容された膨張弁本体2を保持する軟質材料によって形成された弾性保持部412と、少なくとも一部が外部に露出する硬質材料によって形成された支持部411とを有する。【選択図】図3
