本発明は自動車の車体構造に関し、特にハツチ
バツク車やステーシヨンワゴンのバツクドア部の
構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an automobile body, and particularly to the structure of a back door of a hatchback or a station wagon.

ある。 As is well known, in a back door 1 with an upper hinge that opens downward as shown in FIGS. It is sometimes incorporated into the formed drip 4 (see, for example, "Passenger Car Body", Vol. 13, "Automotive Engineering Complete Book" published by Sankaido Co., Ltd.), but this structure has the following drawbacks. That is, since the mounting fulcrums a and b of the conventional gas stay 2 are located on the central axis A of the gas stay 2, even in the closed state of the back door 1 shown in the second and third figures, the flip-up force F 1 due to the stretching force F of the gas stay 2 can be avoided. To obtain the central axis A of the gas stay 2
It is necessary to turn the backdoor 1 by an angle θ with respect to the straight line B connecting the hinge center c and the fulcrum b. The reason for this is due to the one side orientation of gas stay 2.
This is because a component force F 1 =Fsinθ is generated, and a rotational moment about the hinge center c is applied.
ところが、ドリツプ４中でガスステー２を片向

プ機能を阻害する原因となる。 However, when the gas stay 2 is turned to one side in the drip 4, the entire space of the drip 4 is closed by the gas stay 2, as particularly clearly shown in FIG. For this reason, rainwater, etc. flowing down in the drip 4 is dammed up by the gas stay 2, and the rainwater, etc. overflows from the drip 4, causing the drip function to be inhibited.
前述したような従来の欠点を防止するため、本
発明は、ガスステーの車体側の取付支点をガスス
テーの中心から下方偏心させるだけで、ドリツプ
空間の閉塞を防止しようとするものである。 In order to avoid the above-mentioned drawbacks of the prior art, the present invention attempts to prevent the drip space from being blocked by simply eccentrically lowering the mounting fulcrum of the gas stay on the vehicle body side from the center of the gas stay.
以下、第４図及び第５図について本発明の実施
例の詳細を説明する。 Embodiments of the present invention will now be described in detail with reference to FIGS. 4 and 5.
第４図及び第５図は、バツクドア部構造の第２

る。 In FIGS. 4 and 5, the back door 11 is hinged at the upper part to the rear of the vehicle body by a hinge fulcrum c, and a drip 13 is formed at the back door opening edge of the rear fender panel 12 that constitutes the outer panel of the vehicle body. Ru. The space between the drip 13 and the interior 14 is sealed by weather strips 16 and 17 that are fitted onto the inner peripheral flange of the drip 13 and are pressed into contact with the back door inner panel 15.

た位置に選ばれる。 The backdoor 11 is raised by a gas stay 18 located in the drip 13 and implemented according to the invention. The gas stay 18 includes a cylinder tube 18a filled with compressed gas, and a piston rod 18b slidably inserted into the cylinder tube 18a, and the piston rod 18b is pressed by the filled gas. Further, mounting brackets 19 and 20 are fixed to the base end of the cylinder tube 18a and the tip of the piston rod 18b, respectively, and these mounting brackets 19 and 20 are installed on the outer wall of the drip 13 and the back door inner panel 15. It is pivotally supported by pins a and b on stay mounting brackets 21 and 22, respectively. According to the present invention, the position of the pin a is set at a position eccentrically downward from the center line A of the gas stay 18 by a distance α by means such as forming the mounting bracket 19 into a “dog” shape as shown in the figure. selected.

の流れに干渉を起こすことはない。 Therefore, as shown in the fourth diagram, the gas stay 18
Align the center line A of the back door 1 with the straight line B connecting the hinge center c and the fulcrum pin b, or
If the concentric line A is assembled so as to be substantially parallel to the straight line B, the straight line B and the straight line C connecting the fulcrum pins a and b will intersect at an angle θ. As a result,
Due to the force of the gas stay 18, a rotational moment about the hinge center c is applied to the back door 1, and the unlocked back door 1 is flipped up by the gas stay 18. Furthermore, as understood from FIG. 5, the gas stay 18 in this case occupies a position sufficiently distant from the groove bottom of the drip 13, so it does not interfere with the flow of rainwater flowing down inside the drip 13. .
