人のユーザーでは対応が困難であった。Since the conventional connecting device for the upper and lower refrigerators and the like shown in FIGS. 10 and 11 is constructed as described above, the seal member 23b is actually formed on the projection 24 as shown in FIG. Since there is no close contact with, there is a space around the protrusion. Therefore, the airtightness of the duct joint is not sufficiently maintained, and cold air leaks. Further, when the refrigerating room 3, the freezing room 4, etc. are separated or connected, the seal member 23b is severely deteriorated due to aging and loses elasticity, so that it is necessary to replace the seal member with a new one each time. Yes, it was difficult for an amateur user to handle.

れる。According to the second aspect of the present invention, a ring-shaped packing made of soft plastic integrally bonded at the time of molding is provided in the ring-shaped groove of the structural member made of hard plastic forming the outer circumference of the duct end surface of the one housing. Since this annular packing is sealed by being pressed into contact with the structural member made of hard plastic that constitutes the outer circumference of the duct end surface of the other housing, the work of setting the packing is unnecessary and the workability is high and the sealing performance is high. A duct connection device is obtained.
