Claims

[Scope of utility model registration request]

a shaft that is held on the door and can be rotated by a handle;
An extension part that extends in a radial direction from the shaft and rotates as the shaft rotates; and an extension part that is provided in a door frame that forms an opening that is opened and closed by the door, and that allows the extension part to rotate when the door is closed. In a door lock structure having an engaging part that locks and prevents the door from opening, the engaging part stands inward from the door frame and comes into contact with the extending part in the door opening direction when the door is closed. A door lock structure characterized by having a bar.
