For example, in a refrigerator, the door of the vegetable compartment is generally of a drawer type, and the inner peripheral side of the door is closed to the peripheral edge of the front opening of the vegetable compartment. A gasket having a magnet to be attracted is provided. In this type of door device, when opening the door, it is necessary to operate the door in the opening direction against the attraction force of the gasket.

[0003] In order to reduce the operating force when the door is opened, a handle is provided rotatably on the front upper portion of the door, and a lever is provided rotatably. There has been considered a configuration in which a lever is rotated and a front portion of the refrigerator body (a peripheral portion of a front opening portion of the vegetable compartment) is pressed by a pressing portion of the lever. In this case, the pressing portion of the lever is located at the center in the width direction of the door, and protrudes rearward from the door to press the front surface of the refrigerator body. However, in the above-described conventional configuration, the pressing portion of the lever is located at the center in the width direction of the door. Great power is needed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a storage door apparatus which can further reduce the operation force when opening a drawer type door provided with a gasket. .

[0005]

In order to achieve the above object, an invention according to claim 1 is provided on a front surface of a storage body having a storage room so as to open and close a front opening of the storage room, and has an inner surface. A drawer-type door provided with a gasket that is attached to a peripheral portion of the front opening of the storage room in a closed state at a peripheral portion of the storage chamber, a handle provided on the door, and a door having a pressing portion. And a lever that presses the front surface of the storage body by the pressing portion based on the operation of the handle, wherein the pressing portion of the lever is more than the central portion in the width direction of the door. It is characterized by being located on the outside.

In the above structure, when the handle is operated, the gasket is peeled off from the front surface of the storage body by pressing the front surface of the storage body with the pressing portion of the lever based on the operation. At this time, since the pressing portion of the lever is located outside of the center in the width direction of the door, the door does not open parallel to the front surface of the storage body, and the gasket is turned from one side. It will come off. This makes it easier to peel off the gasket than in the case where the pressing portion of the lever is positioned at the center in the width direction of the door, thereby further reducing the operating force when opening the door.

In this case, it is preferable that the handle is located at the center of the door in the width direction (the second aspect of the invention). Further, in a device in which a door cap is mounted on an upper portion of a door and a support member for supporting a handle and a lever is provided on the door cap, the support member restricts deformation of a ceiling surface of the door cap. Protrusions may be provided (claim 3
Invention), the door cap or the support is provided with an off-axis restricting portion that restricts the handle shaft that rotatably supports the handle from coming off the bearing portion (claim 4).
