Claims

[Scope of utility model registration request]

In door hinges, in which the bearing cylinder of the fixed plate attached to the vehicle body side and the bearing cylinder of the movable plate installed to the door side are rotatably connected by a hinge pin, the bearing cylinder of the movable plate is placed above the bearing cylinder of the fixed plate. The overlapping surfaces that come into contact are formed so that they both slope downward to the outside when the door is open, and the overlapping surfaces are always in contact with each other by biasing a coil spring wound around the hinge pin. A door hinge characterized by:
