−３５３０６６号公報参照）。2. Description of the Related Art The basic structure of a lid of a rice cooker is generally a combination of a lid ring made of a plastic, which is an inner member of the lid, and an upper lid plate made of the same plastic, which is an outer member, which are vertically combined to be integrated. The lid ring is provided with a large number of reinforcing ribs in order to maintain the required strength. Further, in the pressure type rice cooker, since further strength is required, a structure is adopted in which a metal reinforcing member is fixed to the upper surface of the lid ring and the lid upper plate covers the reinforcing member and the lid ring. (For example, Japanese Unexamined Patent Publication No. 2001
-353030).

かわすために、適宜な穴が設けられる。The reinforcing ribs of the lid ring described above include a reinforcing wall in the front-rear direction that performs a main reinforcing action along both left and right sides,
It is constituted by a large number of relatively fine vertical and horizontal ribs provided between the outer sides of both the reinforcing walls and the side of the lid ring.
The metal reinforcing member is composed of left and right side walls fitted along the inside of the left and right reinforcing walls and a connecting portion for connecting the bottom sides of the side walls, and has an upward U-shape. The lid ring and the reinforcing member are connected and integrated by a required number of screws. In addition, in order to avoid the steam hole set and the like, appropriate holes are provided in the above-mentioned connecting portion.

A structure is adopted in which an auxiliary member made of a metal plate is bridged between both side walls and the auxiliary member is fixed to the reinforcing member main body with screws.

り、改良の余地があるものであった。From this point of view, looking at the above-mentioned conventional structure,
Although a method of fixing the auxiliary member between both side walls of the reinforcing member main body is a simple method, since the auxiliary member is a metal plate and its strength is insufficient, the auxiliary member is bent to the side to reinforce itself. It is necessary to provide a reinforcing treatment such as providing a portion or forming a bead, and a screw for fixing this to the reinforcing member main body is required. Therefore, the manufacturing cost of the auxiliary member is high, the number of screws is increased, and the work for fastening the screws is required. Therefore, there is room for improvement.

題とする。Therefore, the present invention is based on the idea that the auxiliary member is used to reinforce the main body of the reinforcing member, which is common to the above-mentioned case, and the structure of the auxiliary member and the mounting structure are simplified. An object of the present invention is to provide a reinforcing structure that is low in cost and does not require mounting parts.

された補強ピンとにより発揮される。According to the above construction, a metal reinforcing pin corresponds to the above-mentioned auxiliary member, but the reinforcing pin is made of a single metal wire and has a very simple structure. is there. Further, since the holding is performed by sandwiching and fixing it by the groove provided in the lid ring and the reinforcing member, a component for fixing the reinforcing pin is not necessary. The reinforcing effect in this case is exhibited by the groove provided in the reinforcing member and the reinforcing pin fitted and integrated inside the groove.
