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 area of the retaining member (22) that receives pressure from the resilient member (23) is set so as to be larger than an abutment area of the detent projection (26) against the detent groove (27). This enables a vehicular checker-equipped door hinge device to be provided that does not lose the check function even if part of the check force generation mechanism malfunctions and, moreover, that has high durability.
