PURPOSE:To reduce noise by welding a center pin for supporting a closed case to an end of the closed case at the position to be approximately same as the axis of a motor-operated compression element and more specifically using a pipe material as the center pin. CONSTITUTION:A center pin 10 of a pipe material is fixed by welding to a closed case 2 for directly holding a motor-operated compression element at a position approximately same as the axis of the motor-operated compression element. A front mount 4 is inserted via an anti-vibration rubber 5. While tortional vibrations are produced when the motor-operated compression element compresses a refrigerant, since the center pin 10 is made of the pipe material, the natural frequency of vibration becomes higher and as a result noise produced can be kept small.
