Abstract

A door opening / closing device in which a vehicle body and a door are pivotaly joined by a hinge member and in which a damper for applying braking force to the door when it is opened is provided directly connected to the hinge member. The hinge member (10) has a first hinge arm (11) fixed to a floor (60), a pin shaft (15) fixed to the first hinge arm (11) and projected outward from the first hingearm (11), and a second hinge arm (13) pivotaly joined to the pin shaft (15) and fixed to the lower end of a lower door (41). The damper (20) has a rotor (21) joined to a projection (159) of the pin shaft (15), a housing (23) pivotally attached to the rotor (21) and fixed to the lower door (41), and a braking means (29) provided in the housing (23) and applying urging force to the housing (23) when the housing (23) is rotated relative to the rotor (21).

Description

technical field [0001] The present invention relates to a door opening / closing device for a vehicle, and more particularly, to a door opening / closing device provided with a damper for applying a braking force to a door when the door is rotated relative to a vehicle body. Background technique [0002] As shown in FIG. 10, the rear door 940 for opening / closing the opening of the vehicle body includes an upper door 945 for opening / closing the upper portion of the opening, and a lower door for opening / closing the lower portion of the opening. 941. The upper door 945 is pivotally connected at its upper end to the rear end of the roof by an upper hinge so as to pivot upward and downward. The upper door 945 is flipped up to open the opening. [0003] The lower door 941 is pivotally connected at its lower end to the rear end of the floor panel by a lower hinge so as to turn upward and downward. The lower door 941 is pivoted to a horizontal position to open the opening. [0004] ...
