<p>PURPOSE: A hinge device for a refrigerator door is provided to allow a user to accurately and rapidly perform an assembly work by easily distinguishing the right and left and by increasing the flexible mobility and friction sound according to the friction. CONSTITUTION: A hinge device for a refrigerator door comprises circular male or female member boards(11,21), an uplifted valley(30), an uplifted unit(40), long inclined surfaces(32,42), abrupt inclined surfaces(33,43), and steep slope surfaces(34,44). The abrupt inclined surfaces is located at the height and depth of 3 mm from the male or female member boards and is connected to the peak units(31,42) in a door closing at a direction of 12.26 degrees of a shaft starting point. The steep slope surface is connected to an end of the abrupt inclined surface at 7.01 degrees of the shaft starting point of the male and female member board. The uplifted unit is crossly coupled to the uplifted unit and controls the door.</p> |
