Description

[Detailed Description of the Invention] The present invention relates to a vibration prevention device for an opening/closing body in a vehicle.

As shown in Japanese Utility Model Publication No. 44-15613, a vibration prevention device for an opening/closing body is provided with a wedge on either the opening/closing body side or the car body side, and a striker on the other side, and the fitting relationship between the two is used to prevent the vibrations of the opening/closing body from the left, right, top, and bottom. This is to restrain the vibration of the vehicle, thereby preventing the generation of abnormal noise caused by vibration, and preventing damage to the painted surface caused by contact between the vehicle body panel and the opening/closing body, and the occurrence of rust from this damaged area. It is.

Conventionally, this vibration prevention device has generally provided one striker each under the left and right ends of the opening/closing body, and when the opening/closing body is closed, one wedge is placed each at the corresponding location on the vehicle body. However, in some cases, strikers and wedges were also provided at the lower end of the opening/closing body and the corresponding vehicle body in the same manner as described above.

However, even with the above-mentioned configuration, due to the fitting relationship between the wedge and the striker, the only function is to prevent vertical and horizontal vibrations of the opening/closing body, and the function is to prevent vibrations in the opening/closing direction of the opening/closing body, that is, in the front and back direction. It has no function.

Therefore, it is necessary to install separate stoppers made of elastic material, at least one on each side of the opening end of the vehicle body, or built into the locking device of the opening/closing body, which increases installation time and reduces work efficiency.
In addition, since each component is separate, it is disadvantageous in terms of cost.

Furthermore, in order to reliably prevent vibrations, the striker and wedge have to be large in size, and for those who work with the door open, the protrusions on the opening reduce work efficiency.

The present invention has been made to address these conventional problems, and aims to provide a vibration prevention device that is small and capable of preventing vibrations in the front and rear directions.To achieve this purpose, the present invention has been developed. has the following configuration.

That is, in a vibration prevention device that has a striker on either the opening/closing body side or the vehicle body side of the vehicle and a wedge that fits with the striker on the other side,
The wedge is formed of a base plate, a stopper fixed to one end of the base plate, and a bumper biased by a spring to the other end of the base plate, and the side surfaces of the bumper and the stopper are arranged as shown in FIG. The shape of the contact surface of the striker, which is an inclined surface that expands in the direction of entry of the striker and expands toward the base plate side in front view, and that the side surfaces of the bumper and stopper contact, is shown in plan view and When viewed from the front, this is an inclined surface that expands to complement the side surfaces of the bumper and stopper.

For example, a vibration prevention device 1 for a rear door 3 of a van-type automobile shown in the figure is provided on the left and right lower ends of the rear door 3 side of the vehicle body 2 and on the corresponding vehicle body 5 side. 4 in the figure indicates a door lock.
