Cooking device

A cooking device which heats a food in a heating chamber with a heating medium, an opening of the heating chamber is closed with a door which swings around a horizontal pivot shaft disposed in a lower portion of the cabinet, the cooking device is characterized in that an open/close adjustment device which connects the cabinet and the door with each other and adjusts an operation force needed to open or to close the door, the operation force indicates a maximum value when the door is passing a predetermined angle, the maximum value is given by two protrusions disposed at front-side and rear-side with a distance between them, the protrusions each produce a load when they go over a support member, and a following one of the two protrusions produces a load larger than a load firstly produced by a preceding one of the two protrusions when the door is opened, and inclinations of both sides of the two protrusions are adjusted such that a larger load is produced when the door is opened than when the door is closed and a following one of the two protrusions produces a load smaller than a load firstly produced by a preceding one of the two protrusions when the door is closed, thereby producing a larger operation force needed to open the door than is needed to close the door.
