To provide an automatic bread maker having configuration which transmits rotating force of a motor to a rotary shaft of a bread container by a coupling, and can stably perform power transmission by the coupling.

The automatic bread maker 1 includes: a body side connection part 17 prepared at the bottom of a baking chamber 30 in order to transmit rotating force of motors 50 and 60 to a rotary shaft 82 prepared at the bottom of a bread container 80; and a container side connection part 84 which is prepared at one end of the rotary shaft 82, and composes a coupling with the body side connection part 17 by holding the bread container 80 in the baking chamber 30. The body side connection part 17 has a supporting part 17a, and a projection part 17b which projects from the supporting part 17a, the container side connection part 84 has an arm part 84b, and the projection part 17b and the arm part 84b are overlapped and engaged so that a part in which the arm part 84b becomes lower to the projection part 17b may arise in the state that rotary shaft 82 is rotated by the driving of the motors 50 and 60.
