PURPOSE:A cylinder containing a motor is pressure-inserted into a nearly circular barring hole provided on the back of a cold storage at the position shown by a flange of the cylinder. By this processing and sealing efficiency is increased. CONSTITUTION:Cylinder 34 provided with depression P for fitting motor 32 and also with flange 34a having projection 40 is pressure-inserted into nearly circular barring hole 22b, and opening flange 34a is brought into close contact with back plate 22a by fitting projection 40 of cylinder 34 into conical depression 41 provided around barring hole 22b. One side of conduit 35 is fited to cylinder 34 and other side is fitted to inner box 24. Shaft 33 of motor 32 passes this and extends into the storage. By this, it is possible to eliminate sealing material and fastening screws and to reduce the size of the cylinder. Thus processing and sealing efficiency is increased. |
