Heating cooking apparatus

A heating cooking apparatus comprising:

• a main body including a heating chamber accommodating an object to be heated;
• a door configured to open and close a front face opening of the heating chamber;
• a locking member provided at the door;
• a holding member provided at the main body and configured to hold the locking member to cause the door to be in a locked state;
• a first operation member configured to be displaced between a first position and a second position and to be operated to open the door;
• a second operation member configured to be operated to release the locked state of the door;
• a displacement transmission mechanism configured to transmit a displacement of the first operation member from the first position, and to release the locked state of the door by the holding member by causing the first operation member to be displaced to the second position;
• a displacement transmission limiting member configured to be movable between a limiting position at which at least one of the displacement of the first operation member and the transmission by the displacement transmission mechanism is limited, and a non-limiting position at which neither the displacement of the first operation member nor the transmission by the displacement transmission mechanism is limited;
• and
• a driving unit configured to cause the displacement transmission limiting member to move to the non-limiting position in response to an operation of the second operation member.
