Abstract
An automobile door hinge device includes: an inner cylindrical body integrally connected to a first bracket and rotatably fitted over an outer periphery of a hinge pin; an outer cylindrical body integrally connected to a second bracket to surround the inner cylindrical body; a check spring disposed between the inner cylindrical body and the outer cylindrical body to come into contact with an outer peripheral surface of the inner cylindrical body with a resilient force of the check spring; and first and second control portions that are provided in the inner cylindrical body to face first and second engaging portions, respectively, at opposite ends of the check spring, and displace the first and second engaging portions in directions releasing the contact of the check spring during relative rotation of the inner cylindrical body and the outer cylindrical body. Thus, the door hinge can exert a stepless door check function of holding a door at any opening degree.
