Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a lid opening / closing slide roller provided on a sun roof in a vehicle with a sun roof.

(Prior Art) Conventionally, an opening / closing mechanism of a sun roof 1 of a vehicle with a sun roof as shown in FIG. 5 is, for example, as shown in FIG. 6 and FIG. 7 showing a cross section taken along line AA. . 2 is a sun
This is a roof lid, and bearing brackets 3 are attached to both sides of the lid 2 by bolts 4. A roller shaft 5 is attached to the bearing bracket 3, and the roller shaft 5 has a roller 7 together with a wave washer 6.
Is rotatably inserted. Reference numeral 8 is a channel-shaped rail provided on the vehicle body side, and a roller 7 is disposed slidably along the rail surface in the groove of the rail 8. When opening and closing the sun roof 1, the motor 10 is operated, and the lid 2 connected to the motor 10 via the link 9 moves on the rail 8 by the rotation of the roller 7.

However, in such a conventional slide roller, the sliding resistance between the roller 7 and the rail 8 does not become large, in other words, the roller 7 can move while smoothly rotating along the surface of the rail 8. A gap B as shown in FIG. 8 was provided between the roller 7 and the rail 8. For this reason, when the sunroof 1 is open, there is a problem in that the vibration of the vehicle 7 while running causes a hammering noise of the roller 7 and the rail 8, which causes noise.

(Problems to be solved by the invention) In order to solve the above-mentioned problems, the invention is a sunroof which does not increase the sliding resistance between the roller and the rail and eliminates rattling between them to prevent noise. The purpose is to provide the slide rollers.

(Means for Solving the Problems) The above object is a slide roller that is attached to both sides of a lid of a sun roof and slides on a rail surface on the roof body side, and is supported by a bearing bracket that protrudes from the lid. A roller shaft and a main roller, an intermediate roller, and a sub-roller that are rotatably inserted along the roller shaft in a laminated form.The main roller and the sub-roller are supported by a lower rail surface, and the intermediate roller is Contacting the upper rail surface, which has a bearing portion formed of an elastic body and has a smaller diameter than the main and auxiliary rollers, and further has a distance from the center line of the roller shaft set to be slightly smaller than the radius before deformation of the intermediate roller. Sun arranged to
Achieved by roof slide rollers.

(Operation) In the slide roller of the sun roof configured as described above, the roller supported by the same roller shaft as a whole is elastically sandwiched between the lower rail surface and the upper rail surface, so that there is no rattling. The rollers and rails will not make a tapping sound even when subjected to vibrations while driving. Further, since the intermediate roller is supported through the bearing portion made of an elastic body, the sliding resistance is absorbed even when the lid is opened and closed, and the sliding roller can be smoothly moved.

(Embodiment) The present invention will be described below with reference to the drawings illustrating an embodiment. Figure 1 shows the slide of the sun roof according to this invention.
A longitudinal sectional view of the roller and FIG. 2 are similarly exploded views. In the figure, 11 is a main roller, 12 is an intermediate roller, and 13
Is an auxiliary roller. As shown in FIG. 3, the intermediate roller 12 is composed of an outer ring portion 12a made of hard resin and a bearing portion 12b made of an elastic body such as rubber. The bearing portion 12b may be formed of an elastic resin having a perforated cross section as shown in FIG. Reference numeral 14 is a rail body, the cross section of which is formed in a channel shape having a partially protruding portion.
The rollers 11, 12 and 13 are stacked and inserted into the roller shaft 5, and the bearing bracket 3 is inserted through the wave washer 6.
Mounted on the rail body 14 as shown in FIG.
Is located in. The lower portions of the main roller 11 and the sub roller 13 are in contact with the lower rail surface 15. On the other hand, the upper portion of the intermediate roller 12 is in contact with the upper rail surface 16 of the rail body 14. The distance b from the upper rail surface 16 to the roller shaft center line is set to be slightly smaller than the radius a of the intermediate roller 12 before deformation. Therefore, when the rollers are arranged on the rail body 14, the bearing portion 12b made of an elastic body of the intermediate roller 12 is deformed, and the upper portion of the intermediate roller 12 is in pressure contact with the upper rail surface 16.

In the sun roof slide roller having the above-described structure, the main roller 1 arranged on the rail body 14 is used.
1 and the sub roller 13 are supported by the lower rail surface 15, while the intermediate roller 12 is in a state where the elastic bearing portion 12b is compressed, and its upper portion is in contact with the upper rail surface 16.
Therefore, when the lid 2 of the sun roof is opened and closed, there is no sliding resistance and it can move smoothly. With the lid 2 of the sun roof 1 open, slide
Since the entire roller is elastically sandwiched between the lower rail surface 15 and the upper rail surface 16 of the rail body 14, there is no rattling, and each roller 1 is not affected by vibration while the vehicle is running.
1, 12, 13 and the rail 14 do not generate a tapping sound.

(Effects of the Invention) The present invention uses the sun-roof slide roller having the above-described structure to eliminate the play between the roller and the rail without increasing the sliding resistance between them. Therefore, it is possible to prevent the sun roof from generating noise even while the vehicle is traveling.
