Patent ID: 8108969

Claim:
A checker-equipped door hinge device for a vehicle, comprising: a first bracket fixed to one of a body and a door; a second bracket fixed to another one of the body and the door; a hinge pin connecting the first and second brackets to each other, and allowing the brackets to be relatively rotatable; an inner cylinder connected integrally to the first bracket and disposed coaxially with the hinge pin; an outer cylinder connected integrally to the second bracket and disposed so as to surround the inner cylinder in a manner of being rotatable relative to the inner cylinder, wherein longitudinal axial end faces of at least one of the inner and outer cylinders are parallel relative to an inner surface of the first and second brackets; and a plurality of checking-force generating mechanisms are arranged in a circumferential direction of the outer cylinder, are spaced angularly relative to each other, and provided between the inner cylinder and the outer cylinder, the checking-force generating mechanisms generating a checking force against the door at a predetermined opening position for the door, wherein an inner peripheral surface and an outer peripheral surface of the outer cylinder are eccentric to each other, so that a thick wall portion having a large distance between the inner peripheral surface and the outer peripheral surface is formed in the outer cylinder, and the checking-force generating mechanisms are provided in the thick wall portion of the outer cylinder.
