Summary:PROBLEM TO BE SOLVED: To provide a cryogenic refrigeration device advantageous for suppressing wearing of a contact surface which presses the leading end of a stem.SOLUTION: A leading end 41 of a stem 40 of a valve body 4 slid into contact with the contact surface 50 of a valve driving member includes a rotor 44. The rotor 44 is rotated to reduce friction resistance between the leading end 41 and the contact surface 50, thereby suppressing wearing of the contact surface 50.
