Abrégé

A door hinge device adapted for use in a vehicle and equipped with a checker, wherein a check force generation mechanism comprises a center shaft (6) which is affixed to a female bracket (1), a cylinder block (7) which is affixed to a male bracket (2) and has a cylinder section (7b), a piston (22) which is fitted and mounted in the cylinder section (7b), a detent roller (26) which is supported by the piston (22), a check spring (23) which presses the piston (22), and a detent groove which is provided in the outer peripheral surface of the center shaft (6) and with which the detent roller (26) is engaged by means of the pressing force of the check spring (23). The male bracket (2) comprises: male arm sections (2b) which are disposed in such a manner that, inside female arm sections (1b), the male arm sections (2b) sandwich the cylinder block (7); and male base sections (2a) which are interconnected with the male arm sections (2b). The male arm sections (2b) are secured to the cylinder block (7), and both ends of the center shaft (6) which penetrates through the male arm sections (2b) are secured to the female arm sections (1b). The configuration enables the male bracket to be disposed without being influenced by the arrangement of the cylinder block, and as a result, the door hinge device can be reduced in size.

Abrégé

Provided is a vehicular door-hinge device with a checker, which comprises an inner cylinder (6) to be jointed to a female bracket (1), an outer cylinder (7) to be jointed to a female bracket (2), and a check force generating mechanism (20) interposed between the two cylinders (6 and 7). The mechanism (20) is constituted of a plurality of holding members (22) attached to the outer cylinder (7) and arrayed in the circumferential direction of the same, and a plurality of elastic members (23) for biasing those holding members (22) individually toward the inner cylinder (6). Each of the holding members (22) is equipped with a detent projection (26) for abutting against the outer circumference of the inner cylinder (6). The inner cylinder (6) is equipped, in its outer circumference, with a plurality of detent grooves (27), into and out of which the engagements of the detent projections (26) are made according to the relative rotations of the inner cylinder (6) and the outer cylinder (7). The pressure receiving areas of the holding members (22) for receiving the pressures from the elastic members (23) are set larger than the abutting areas of the detent projections (26) and the detent grooves (27). As a result, the vehicular door-hinge device does not lose the checking function, even if the check force generating mechanism is partially troubled, but is high in durability.
