A cooking device having a drawer type automatic door in which delicate control is carried out when the door is opened and closed, whereby influence exerted on an object to be cooked by a shock produced at the time of door opening and closing can be reduced or eliminated. When a before-stop position (full opening detection switch Pso at the time of full opening, intermediate switch Psi at the time of full closing) provided before the stop position of the door is detected, the travel speed of a drawer body is controlled. A speed control is configured to reduce the speed of the drawer body in response to the arrival of the drawer body at a before-stop position and increase the closing speed of the drawer body in response to the arrival of the drawer body at a latch riding position.
