Claims

[Scope of utility model registration request]

A door hinge provided between the upper and lower parts of the front surface of the door and the opposing vehicle body member is divided into a vehicle body side hinge bracket fixed to the vehicle body member, a door side hinge bracket fixed to the door front surface, and the vehicle body side hinge bracket. In a door hinge for an automobile door, the front link and the rear link are each configured to have one end pivotally attached to the door side hinge bracket and the other end pivotably attached to the door side hinge bracket. It has a front curl part and a rear curl part that are respectively fitted to the front and rear shafts of the link to the vehicle body side hinge bracket, and extends from the front curl part to open the front link within a predetermined opening range from fully closed door. The front arm part elastically contacts the shaft attached to the door side hinge bracket and applies a spring force in the door opening direction, and the rear arm part extends from the rear curl part and is attached to the door side of the rear link during the middle and late stages of the door opening operation. The door checker is made of a leaf spring material and has a rear arm part that interferes with the axis attached to the hinge bracket and overcomes it to provide resistance in the door opening direction. A door checker device for an automobile door, characterized in that the rear link is fitted onto the shafts of the rear link on the vehicle body side hinge bracket and assembled.
