PURPOSE:To increase the joining strength of a discharge pipe and a container by bringing a flange fixed in the middle of a discharge pipe into butt contact with the inner peripheral face of a hole at the top of the container from the inside of the container, and at the same time, fixing the discharge pipe to the container by a bolt studed to the flange. CONSTITUTION:A flange 66 is screwed to the projected end of a discharge pipe 38 connected to refrigerant circulating pipe, and at the same time, a different flange 70 is fixed in the middle of the discharge pipe 38. The upper face of the flange 70 is brought into butt contact with the inner face of the container around a through-hole 48 provided at the top of the container 14 through a gasket 80, and the discharge pipe 38 is fixed to the container 14 by a bolt 72 inserted into a bolt hole 76 pierced around the through-hole 48 of the container 14, and a nut 78 screwed to the bolt 72 from the outside of the container. Consequently, the fitting strength of the discharge pipe can be made high enough to resist a load caused by a difference of thermal expansion. |
