望されている。 In the conventional toaster oven mentioned above, in order to operate the operating lever by pressing down, it is necessary to form a guide groove on the front panel of the toaster body to move the operating lever in the vertical direction. It is not possible to provide operating parts for other switches, etc., and recently it has become difficult to provide the operating parts for various mechanisms that have been added to improve the functionality of toasters on the same front panel, so the front panel has to be made larger. The need arose. Therefore, there is a demand for a structure in which the actuation is performed using a push button on the front panel that requires a small area for actuation, instead of an actuation lever that moves up and down.
