Abstract: A vehicular checker-equipped door hinge device is provided that includes an inner tube (6) joined to a female bracket (1), an outer tube (7) joined to a male bracket (2), and a check force generation mechanism (20) provided between the two tubes (6, 7), the mechanism (20) including a plurality of retaining members (22) that are mounted on the outer tube (7) so as to be arranged in the peripheral direction and that are capable of moving toward and away from the inner tube (6), and a plurality of resilient members (23) individually urging these retaining members (22) toward the inner tube (6); each of the retaining members (22) is provided with a detent projection (26) projecting so as to abut against an outer peripheral face of the inner tube (6), a plurality of detent grooves (27) that the detent projection (26) engages with and disengages from in response to relative rotation of the inner tube (6) and the outer tube (7) are provided on the outer peripheral face of the inner tube (6), and a pressure-receiving

Abstract: In order to ensure that a door can be retained at least in a fully opened position and a slightly opened position by the combination of a smaller number of exclusive parts with a hinge connecting a body and a door in a door retention device used in a process of manufacturing an automobile, the door retention device includes a torsion spring 23 mounted to a first hinge arm 1 of a door hinge H, and a cam 20 formed on a second hinge arm 2 of the door hinge H. The cam 20 is provided with a first positioning recess 20a and a second positioning recess 20b in which a movable arm portion 23c of the torsion spring 23 is brought into engagement in the fully opened position F and the slightly opened position S of the door D, and a projection 20c disposed between the first and second positioning recesses 20a and 20b and adapted to apply a load to the movable arm portion 23c in accordance with the turning of the door D.
