Since the conventional drawer door device of the refrigerator is configured as described above, the load of the drawer door is always applied to the fixed roller 8, and the fixed roller mounting portion is worn by opening and closing of the drawer door. No. 9 needs to use a strong and highly wear-resistant material, and has to cope with a material such as PP (polypropylene) due to cost and the like.
For this reason, when the fixed roller mounting portion is worn or damaged at the customer or the like, there is only a means to replace the product body, and the serviceability is not at all.

  Furthermore, since the roller mounting portion has a concave shape, water tends to accumulate in the recess and is unsanitary. If the roller mounting portion is a freezer compartment, the fixed roller 8 slides at all due to freezing of water. Therefore, there is a problem that opening and closing of the drawer door becomes very difficult.

  In recent years, products with large drawer-type cases have been increasing in the middle part of refrigerators, such as vegetable rooms and switching rooms, and a large burden is placed on the support parts (roller mounting parts, frames, etc.) of drawer doors. ing. Furthermore, there is a possibility that an excessive load is applied such as a child hanging on the drawer door in a state where the drawer door is pulled out, and it is necessary to reinforce the support portion of the drawer door. In particular, since the lower inner partition wall 9 supporting the fixed roller mounting portion is made of synthetic resin such as PP, the impact resistance is inferior, and the periphery of the fixed roller mounting portion may be deformed and damaged.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a refrigerator in which the drawer door does not fall outside when the drawer door is pulled out.

  A refrigerator according to the present invention is provided with a refrigerator body, a partition wall for partitioning the storage chamber of the body, a partition wall having a partition steel plate on the front surface, a frame provided in the storage chamber and on which a food storage case is placed. A drawer door, a fixed roller that is provided on the main body and supports the frame from below, a fixed roller storage portion that is provided on the intermediate partition wall, stores the fixed roller, and is formed as a separate part from the intermediate partition wall, and the frame And a convex portion that comes into contact with the fixed roller and serves as a stopper in a state where the drawer door is pulled out.

  In the refrigerator according to the present invention, the drawer door does not fall to the outside due to the configuration including the convex portion that comes into contact with the fixed roller and serves as a stopper while the drawer door is pulled out.
