Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door check device.

[0002]

2. Description of the Related Art Conventionally, an automobile door is kept open by a door check device to prevent the door from being naturally closed due to the inclination of the slope and the weight of the door on a slope or the like, and to prevent the door from being suddenly closed by wind. It regulates the door from closing to prevent accidents such as pinching a finger.

As a concrete structure of the door check device, for example, as shown in FIG. 8, a lever 103 supported on the vehicle body side and having a raised portion 101 on the upper surface of the lever, and a lever 103 supported on the door side and penetrating the lever 103. Holding member 105
The holding member 105 includes a holding case 109 having an opening 107 through which the lever 103 penetrates, a slider 111 disposed in the holding case 109 and slidingly displacing the lever upper surface in accordance with the opening / closing operation of the door, It is formed of an elastic body 113 that urges the slider 111 toward the upper surface of the lever.
Reference numeral 115 denotes a stopper, and one having such a structure is described in, for example, Japanese Utility Model Publication No. 3-21587.

[0004]

According to such a door check device, when the door is opened / closed, the slider 111 is slidably displaced corresponding to the protrusion 101 on the upper surface of the lever. At this time, the elastic body 113 is pressed and compressed when the slider 111 rides on the upper surface of the raised portion 101. When the user descends from the raised portion 101, the pressure is released and the original state is restored. When the elastic body 113 is compressed and returned, the both side surfaces 117 slide while contacting the inner wall surface of the holding case 109, so that a sliding noise is generated.

[0007] This slipping sound impairs the sense of quality,
Generally, the holding case 109 is filled with a lubricant such as grease to smooth the movement of the elastic body 113 during compression and restoration.

However, both side surfaces 117 of the elastic body 113
And the inner wall surface of the holding case 109 during compression,
Both side surfaces 117 swell and a relatively strong contact pressure acts. As a result, there is a problem that the grease is wiped off and the contact area causes a kind of oil shortage state, and this oil shortage state becomes remarkable with the passage of time.

[0007] Therefore, an object of the present invention is to provide a vehicle door check device which eliminates oil shortage in the contact area on both side surfaces of the elastic body and can obtain a smooth operating state for a long time.

[0008]

In order to achieve the above object, the present invention provides a lever supported on the vehicle body side and having a raised portion on the upper surface of the lever, and a holding member supported on the door side and through which the lever penetrates. In a vehicle door check device including the holding member, a holding case having an opening through which a lever penetrates, and a slider arranged in the holding case and slidingly displacing an upper surface of the lever according to opening / closing operation of the door. , The elastic body that urges the slider toward the upper surface of the lever, and the elastic body that comes into contact with the circular wall surface of the holding case is disposed substantially parallel to both side surfaces of the elastic body and penetrates forward and backward. A pair of vertically elongated deformation absorbing holes is provided.

Alternatively, a pair of upper and lower groove-shaped oil sumps are formed on both side surfaces of the elastic body which are in contact with the inner wall surface of the holding case, and are formed over the entire area from the groove-shaped oil sumps to the oil sumps. And a flat oil reservoir.

[0010]

According to such a door check device, when the door is opened and closed, the slider is slidably displaced corresponding to the ridge on the upper surface of the lever. At this time, the elastic body is pressed and compressed when the slider climbs up from the general surface to the upper surface of the raised portion, and when the slider moves down from the raised portion, the pressing is released and the original state is restored. When the elastic body is compressed or returned, both side surfaces slide while contacting the inner wall surface of the holding case. At this time, even if a vertical compression force is applied to the elastic body, both sides do not bulge outward significantly due to the deformation of the vertically long deformation absorption holes or the planar oil sump with steps, and a strong contact is achieved. No pressure occurs. As a result, the wipe-off of grease or the like can be suppressed to be small, and smooth operation can be obtained for a long period of time.
