うにしてある。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 4 to 9, reference numeral 1 denotes a refrigerator, which is provided with a freezing compartment 1a on the upper side and a refrigerating compartment 1b on the lower side. 2 is a heat insulating box consisting of an inner box 3, an outer box 4, and a polyurethane foam heat insulating material 5 filled between both ends 3 and 4. An upper door 6 and a lower door 7 are provided at the front openings of each of the chambers 1a and 1b, respectively, so as to be openable and closable. 8
9 is the door insulation material, and 9 is the gasket. Freezer compartment 1a
A cooler 10 is disposed within a partition 1c of the refrigerator compartment 1b, and a fan 11 discharges cold air into the freezer compartment 1a and the refrigerator compartment 1b. The amount of cold air to the refrigerator compartment 1b is adjusted by a partition plate 14 of a manual cold air adjustment damper 13 provided in a blow-off grill 12 provided in the refrigerator compartment 1b. The upper end of this partition plate 14 is an inverted U.
An auxiliary plate 14b that is bent into a letter shape and hangs down to approximately 1/2 of the partition plate 14 is integrally formed. Furthermore, a small hole 14c is provided in a part of the partition plate 14,
A portion of the cold air flows to the back surface of the auxiliary plate 14b through this small hole 14c, and dew condensation water generated on the auxiliary plate 14b is sublimated to prevent freezing. This partition plate 14 is supported within a duct 15 having a rectangular cross section by a shaft 14a formed integrally with the partition plate 14. Both ends of the shaft 14a are rotatably engaged with groove-shaped engagement portions 16 formed in opposing side walls 15a of the duct 15. 17 is for the shaft 14a,
The barrier wall is formed integrally with the duct 15 so as to extend from the windward side and have a gap 18 with the side wall 15a, and the upper and lower ends of the barrier wall 17 function as stoppers 17a and 17b for regulating the rotation range of the partition plate 14. There is.

る。 Therefore, the flow of cold air passing through the duct 15 is changed by the barrier wall 17, and does not directly hit the shaft 14a and the engagement groove 16 that rotatably supports it, thereby avoiding freezing of both. At the same time, when the partition plate 14 is opened, its lower side is the stopper 17b.
In addition, when it is closed, its upper side abuts the stopper 17a, thereby regulating its rotation.

のである。Effects of the Invention As described above, the present invention provides an engaging portion on the opposing side walls of the duct, and the engaging portion is provided with the partition plate 14.
A shaft is fitted to form a barrier that extends from the windward side of the side wall with a gap in the engagement part, and the end of this barrier serves as a stopper that restricts the rotation range of the partition plate. It is possible to simultaneously avoid the phenomenon of freezing on the engagement portion where the shaft of the plate and the duct are attached, and to have a stopper structure for adjusting the opening/closing angle of the partition plate.
