To take a measure for safety against carelessness of a user in a bread baking machine.

This bread baking machine is for backing dough by holding the dough between a pair of metal die plates 2 and 3, and heating both form plates 2 and 3. When the form plates 2, 3 are set in a roughly horizontal attitude, the upper form plate 2 is supported by dampers 11 and 12 to be prevented from falling downward exceeding a certain degree. When the upper form plate 2 is released from hands, therefore, the form plate 2 can be prevented from falling with momentum by its weight to collide with the lower form plate 3.
