車両ドア用ヒンジ
Document Type and Number:
Japanese Patent JP4894952
Kind Code:
B2
Abstract:
A coating film (P) capable of restricting an electric current from flowing from a rotation shaft member (40) to each of slide bushes (50) is formed in a portion of an outer circumferential surface (40c) of the rotation shaft member (40), which portion includes a part (S2, S3) of a contact portion thereof that slidably contacts each of the slide bushes (50) in a rotational axis direction and at least a proximity range (S4) thereof that is positioned in proximity to an exposed end periphery (53) of each of the slide bushes (50). Therefore, when ED coating as a rust prevention measure is applied to a vehicle main body (M1), an ED coating film that can possibly be cracked and peeled off does not exist in boundary portions between the rotation shaft member (40) and the slide bushes (50). Therefore, even when the slide bushes 50 are rotated relative to the rotation shaft member 40, so-called "coating irregularity" cannot be generated in a subsequent coating process. To the contrary, as an electricity supply portion (S1) of the rotation shaft member (40) of the vehicle door hinge (10) is set to "3.5 mm," the electric current from the female bracket (20) can be supplied to the slide bushes (50) via the rotation shaft member (40) without any resistance.
