Abstract:
A checker-equipped door hinge device for vehicle includes: 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; and a checking-force generating mechanism provided between the inner cylinder and the outer cylinder, the checking-force generating mechanism generating a checking force against the door at a predetermined opening position of 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 mechanism is provided in the thick wall portion. Thereby the door hinge device can be compact, in which the checking-force generating mechanism can be disposed in the outer cylinder without increasing the diameter of the outer cylinder.
