Abstract

To provide a vehicle door opening / closing device arranged to pivotally connect a vehicle body and a door with a hinge member and provided with a damper arranged to impart a braking force to the door when the door is turned, the damper being directly connected to the hinge member, the hinge member 10 includes a first hinge arm 11 fixed to a floor 60, a pin shaft 15 fixed to the first hinge arm 11 and extending outward of the first hinge arm 11, and a second hinge arm 13 pivotally mounted on the pin shaft 15 and fixed to a lower end of a lower door 41, and the damper 20 includes a rotor 21 connected to a projecting portion 159 of the pin shaft 15, a housing 23 rotatably mounted on the rotor 21 and fixed to the lower door 41, and a braking means 29 contained in the housing 23 to impart a braking 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] Such as Figure 10 As shown, a rear door 940 for opening / closing an opening of the vehicle body includes an upper door 945 for opening / closing an upper portion of the opening, and a lower door 941 for opening / closing a lower portion of the opening. 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] ...
