PROBLEM TO BE SOLVED: To provide a freezing device dispensing with accurate cutting work and press-fitting process, capable of being produced at low cost, easily coping with a model whereby a refrigerant passing noise countermeasure is not required, and capable of exhibiting excellent noise reduction efficiency. SOLUTION: In this freezing device wherein a connecting pipe 4 equipped with a flange part 41 and a seal groove part 43 is connected to a high pressure side passage 32 of an expansion valve 1, a throttling member 6 is inserted into the connecting pipe 4 so that a throttling part 64 is formed. The throttling member 6 exhibits excellent productivity and attaching characteristics and is effective for reducing the cost when the throttling 6 is formed by a cylindrical body made of rubber or resin.
