In the lock mechanism, since a gap or the like is provided on the bottom surface of the ignition button, when the stove is viewed from the front, the gap or the like is exposed to the outside through the gap between the ignition button and the frame, which spoils the aesthetic appearance. There was a problem. In order to solve such a problem, for example, it is conceivable to make the gap between the bottom surface of the ignition button of the frame member and the top surface of the lower frame portion of the frame body adjacent to the bottom surface portion as small as possible. However, since the portion of the ignition button that is pivotally supported is located on the back side of the front portion of the ignition button, the lower end of the front portion of the ignition button draws a trajectory that sneaks into the lower side during the ignition operation. As a result, when the bottom surface of the ignition button and the lower frame of the frame are brought close to each other, the bottom surface of the ignition button may interfere with the upper surface of the lower frame.

An object of the present invention is to provide an ignition button unit and a stove that can prevent the bottom surface of the ignition button from being exposed to the outside during the ignition operation while providing a mechanism for locking the operation of the ignition button. ..
