Since the drawer door device of the conventional refrigerator is constructed as described above, the load of the drawer door is always applied to the fixed roller 8, and the fixed roller mounting portion is opened and closed by opening and closing the drawer door. Since the lower partition wall 9 is worn, it is necessary to use a material which is strong and has high abrasion resistance, and has to be made of a material such as PP (polypropylene) in terms of cost and the like. For this reason, when the fixed roller mounting portion is worn or damaged at a customer or the like, the only option is to replace the product main body, and the serviceability is almost equal.

Further, since the roller mounting portion has a concave shape, water easily accumulates in the concave portion, which is unsanitary. If the roller mounting portion is a freezing room, the water freezes and the fixed roller 8 is completely removed. There is a problem that the drawer door becomes very difficult to open and close without sliding.

In recent years, the number of products provided with a large drawer-type case in the middle section of a refrigerator, such as a vegetable room, a switching room, etc., has been increasing. The burden is on. Further, in a state where the drawer door is pulled out, an excessive load may be applied such as a child hanging on the drawer door, and it is necessary to reinforce the support portion of the drawer door. Especially, since the lower partition wall 9 supporting the fixed roller mounting portion is made of a synthetic resin such as PP,
Poor impact resistance, and the periphery of the fixed roller mounting portion was sometimes deformed and damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and it is possible to improve the serviceability of a roller mounting portion, keep the roller mounting portion hygienic, and prevent the drawer door from being opened and closed. It is an object of the present invention to provide a refrigerator that can prevent such a problem.
