Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an opening device for an opening/closing body such as a trunk lid of an automobile, and particularly relates to an opening device for a vehicle opening/closing body using a torsion bar.

(Prior art) Conventionally, this type of vehicle opening/closing body opening device includes:
For example, there are the ones shown in FIGS. 4 to 7. That is, 1 is a trunk lid as an opening/closing body, and this trunk lid 1 is connected via a pair of hinge arms 2 to a rear parcel 3 of a vehicle body so as to be openable and closable. A crank portion 6 provided at the movable end of a torsion bar 5 is pivotally connected to one hinge arm 2 via a link 4. The shaft portions 7 and 8 on the fixed end 5a side and the movable end side of the crank portion 6 of this torsion bar 5 are respectively rotated into the first and second locking grooves 10 and 11 of the movable side locking portion 9 provided on the vehicle body. It is movably locked. On the other hand, the fixed end 5a of the torsion bar 5 is engaged with the fixed side locking part 12 and applies an urging force to the hinge arm 2 in the direction of opening the trunk lid 1 through the link 4 which is pivotally supported by the crank part 6. To install the torsion bar 5, hook the crank part 6 of the torsion bar 5 onto the link 4, and
The shaft portions 7 and 8 extending on both sides of the crank portion 6 of the torsion bar 5 are connected to the first and second locking grooves 10,
11. In this state, the fixed end 5a of the torsion bar 5 was pulled out to the front, twisted from the front side of the vehicle body to the rear side of the vehicle body using a jig 13, and fixed to the fixed locking part 12 with the jig 13 in the twisted state. Such a link-type vehicle opening/closing body opening device is described, for example, in "Automotive Engineering Zensho," Vol. 13, "Passenger Car Body," page 150, published by Sankaido Co., Ltd.

(Problems to be Solved by the Invention) However, in the case of such a conventional example, the first and second locking grooves 10, in which the shaft portions 7, 8 extending on both sides of the crank portion 6 of the torsion bar 5 are locked; Since the torsion bar 11 was formed linearly in the horizontal direction, it was easy to lock the torsion bar 5 in the first and second locking grooves 10 and 11. When the other end of 5 is pulled out backwards, the torsion bar 5
The first locking groove 1 on the front side is
The torsion bar 5 easily comes off from the zero position.
Therefore, after twisting the torsion bar 5, when locking the other end of the torsion bar 5 to the fixed side locking part 12, it is necessary to lock the torsion bar 5 again to the first locking groove 10, which makes the work extremely difficult. It was a hassle. In this case, if you try to force the torsion bar 5 into the first locking groove 10, there is a risk that it will come off the second locking groove 11 as well, so you have to be careful. Furthermore, if the torsion bar 5 is bent in the middle of the layout, the installation work becomes even more difficult.

Therefore, as shown in FIG.
It is conceivable to lock it by 11'. In this way, even when the torsion bar 5 is pulled out backwards to twist, the torsion bar 5 can be attached to the hook 1.
There is no possibility that it will deviate from 0', 11'. However, although the hooks 10' and 11' can prevent the torsion bar 5 from falling off, when the torsion bar 5 is locked to the hooks 10' and 11', the torsion bar 5 is not parallel to the vehicle width direction, but is attached to the hooks 10' and 11'. Coupled with the fact that the locking side of the locking side is held forward and inserted, the insertion position is located above compared to the locking groove formed in a straight line in the horizontal direction, that is, Since it is close to the rear parcel 3, the hook 10' on the near side is visible, so it is easy to lock the shaft part 7 on the near side of the crank part 6, but the hook 11' on the back side is not visible. This made locking work difficult. In particular, when the distance of the torsion bar 5 from the rear end of the persiel 3 is large due to the layout of the persiel 3 in which the hooks 10' and 11' are provided, the work becomes even more difficult.

The present invention has been made to solve the problems of the prior art described above, and its purpose is to provide a vehicle opening/closing body opening device in which the installation work of the torsion bar is easy.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, the shaft portions extending to the fixed end side and the movable end side of the crank portion provided at the movable end of the torsion bar are attached to the vehicle body. The fixed end of the torsion bar is rotatably locked in the provided first and second locking parts, and the fixed end of the torsion bar is locked in the fixed side locking part, and the hinge arm is connected through a link connected to the crank part. In the opening/closing body opening device for a vehicle that applies a biasing force in the opening direction of the opening/closing body, a shaft portion extending toward the fixed end side of the crank portion of the torsion bar is engaged with a first locking portion in a horizontal direction of the shaft portion. A hook for preventing movement of the torsion bar is provided, and a locking groove for allowing the shaft portion of the torsion bar to move in the horizontal direction is provided in the second locking portion.

(Function) To assemble the torsion bar, first, the link is pivotally connected to the crank part, and the shaft part extending to the fixed end side and the movable end side of the crank part is engaged with the first and second locking parts. Next, pull out the other end of the torsion bar and twist it, and after twisting, fix it to the fixed side locking part. When setting the crank part of the torsion bar, first insert it into the second locking part, which is difficult to see.The second locking part is formed at a relatively distance from the rear parcel, and is horizontal. Since the locking groove allows movement in the direction, it is only necessary to move the torsion bar in the horizontal direction after it has been brought to the insertion position, making the locking operation easy. Then, the user performs the locking operation on the first locking portion, which can be performed while visually confirming the operation. Further, even if the torsion bar is pulled out in the horizontal direction to twist the torsion bar, the torsion bar will not come off from the first locking part because the hook is provided in the first locking part.

(Example) The present invention will be explained below based on the illustrated example. In FIG. 1 showing the vehicle opening/closing body opening device according to the first embodiment of the present invention, the same components as in the conventional example are designated by the same reference numerals and will be explained as follows.
