Description

【考案の詳細な説明】本考案は自動車のバツクドアーの枢着装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pivoting device for a back door of an automobile.

自動車のバツクドアーの枢着について、バラン
サによつて閉鎖方向にバランス力を付与し、開閉
操作力を軽減したものがあるが、従来においては
バランサが外部に露呈しており、そのため見栄え
が悪く、また耐候性並びに組付性に問題があつ
た。 Regarding the pivoting of the back door of a car, there is a system that uses a balancer to apply a balancing force in the closing direction and reduce the opening/closing force, but in the past, the balancer was exposed to the outside, which made it look bad, and There were problems with weather resistance and ease of assembly.

本考案は上記従来の問題点に鑑み、バランサが
外部に露呈することなく、また組付を容易にした
バツクドアーの枢着装置を提供するものである。 In view of the above-mentioned problems of the conventional art, the present invention provides a back door pivoting device in which the balancer is not exposed to the outside and is easy to assemble.

A hinge guide member 8 is fixedly provided, which is concentric with the shaft 7 and into which the outer peripheral surface of the hinge sleeve 4 is fitted. A synthetic resin bushing 9 is fixed to the inner circumferential surface of the hinge guide member 8, and is provided as necessary to improve rotational sliding of the hinge sleeve 4.

付与した状態で係止するものである。 Since the present invention has the structure as described above, by rotatably fitting the hinge sleeve 4 to the hinge guide member 8, the torsion spring 5 is inevitably inserted and guided through the guide shaft 7, and the back door 2
is pivotally connected to the end post 3 so as to be openable and closable. The other end 5b of the torsion spring 5 is locked to the bracket 6 while applying a balancing force in the closing direction of the back door.

円滑な回転動作を保持する利点がある。 According to the above-mentioned structure of the present invention, after the backdoor is pivotally connected to the end post, the balancer mechanism consisting of the torsion spring is not exposed to the outside at all, which improves the appearance and has weather resistance.
Retains functionality for a long period of time. In addition, assembly is simply done by fitting the hinge sleeve onto the hinge guide member.
Since it is completed by simply locking the other end of the torsion spring, assembly is quick and easy, and the hinge guide member acts as a rotation bearing for the hinge sleeve, increasing the support rigidity of the back door.
This has the advantage of maintaining smooth rotational motion.
