PURPOSE:To improve the processing and sealing efficiency by arranging such that a cylinder containing a motor and having a suspension flange is inserted into a fitting hole which is provided on the backpressure plate of a cold storage and fitted with a bent flange. A conduit is provided on the flat part of the bottom of the cylinder. CONSTITUTION:Suspension flange 34a provided around cylinder 34 provided with depression P for fitting motor 32 is fitted to bent flange 22c provided around fitting hole 22b which is provided on back plate 22a of a cold storage. Both flanges are fitted tight by exerting pressure on their surrounding parts. Cylinder 34 is fitted to back plate 22a. The bottom of cylinder 34 is made flat. Conduit 35 is fitted in such a way that one side of it is brought into close contact with the flat part of the bottom and the other side is brought into contact with the side of the inner box. Motor 32 and fan 31 are connected by extending motor shaft 33 into the inside of the storage. By this, it is made possible to eliminate sealing material and fastening screws and to reduce the cylinder diameter. Thus, processing and sealing efficiency is increased. |
