BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rotary connector device for supplying electric power to an air bag provided on a pad portion of a steering wheel of an automobile, and particularly notes on handling the rotary connector device. The present invention relates to a technique for improving the structure for attaching a label.

2. Description of the Related Art Recently, when a vehicle has a collision accident,
An airbag device has been developed that protects an occupant by igniting an inflator to inflate an airbag. In this airbag apparatus, for example, an airbag and an inflator are built in a steering pad portion, and electric power is supplied from the vehicle body side to ignite the inflator in the event of a vehicle collision. And from the vehicle body side to the steering pad part,
Electric power is supplied using a rotary connector device.

In this rotary connector device, the rotation of the steering handle is hindered by the rotary connector device unless it is mounted on the vehicle body with the steering handle in the neutral position. It is also an important part that supplies electric power to the airbag, and requires careful handling. For this reason, in this rotary connector device, a label on which precautions regarding handling, a label for securing a neutral position, and the like are attached to the housing. For example, a conventional technique of attaching a label for temporarily fixing to a neutral position to a housing of a rotary connector device is disclosed in Japanese Utility Model Laid-Open No. 64-2653.

However, when the label is attached to the housing, an air pocket may be generated between the housing and the label, and the label may be uneven, resulting in a poor appearance. In addition, the accumulated air may expand and contract due to the rise and fall of the temperature, and the label may be peeled off.

[0005]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to prevent air pockets from being generated between the housing and the label when the label is attached to the housing. To do. This prevents unevenness of the label and peeling.

The present invention provides the following means in order to achieve the above object. That is, the present invention relates to a rotary connector device for electrically connecting a steering side and a vehicle body side by a flexible cable housed in a housing in a spiral shape, wherein the housing has a vent hole on a label sticking surface. To provide a structure for attaching a label on a housing in the above.

Also, in the above invention, there is provided a label attaching surface structure for a housing in a rotary connector device, wherein a plurality of recesses are formed on the label attaching surface and the recesses are communicated with each other by the vent holes.

Further, in the above invention, there is provided a label attaching surface structure of a housing in a rotary connector device in which the vent hole is opened toward the center of the housing.

1 and 2 show preferred embodiments according to the present invention. In the figure, reference numeral 1 denotes a housing, which is rotatably mounted on a stator housing (not shown) and is electrically connected to a connecting pin 11 for connecting to a steering handle (not shown) and a circuit on the steering handle side. And an electric wire 12 connected to the.
A flexible cable (not shown) is spirally housed in a donut-shaped space formed by the housing 1 and the stator housing.

The housing 1 has a plurality of recesses 14 formed by thinning the label attaching surface 13 on the side facing the steering handle. The plurality of recesses 14 are
It is formed to prevent so-called "sinker" when the housing 1 is injection molded. This label surface 13
Ventilation holes 15 connect between the recesses 14 formed in 1. The passage formed by the vent hole 15 is open at the center of the housing 1, that is, the side where the steering shaft is fitted.

The level 2 is attached to the label attaching surface 13 of the housing 1. This label 2
Is composed of a resin film or synthetic paper coated with an adhesive on the back side, and notes on handling the rotary connector device are printed on the front side.

As described above, when the label 2 is attached to the housing 1, the space inside each recess 14 communicates with the external space of the connector device, that is, the atmosphere, through the vent hole 15. Therefore, regardless of whether the ambient temperature rises or falls, the two spaces are always at the same pressure,
There is no problem that the label 2 becomes uneven and the appearance is deteriorated, or that the label 2 peels from the label sticking surface 13 due to the expansion and contraction of air.

In the rotary connector device in which the label 2 is attached to the housing 1, one is used as an airbag device (not shown) on the steering handle side and the other is used as an airbag controller (not shown) on the vehicle body side. Connect each. Thus, for example, when a car has a collision accident, the electric signal from the airbag controller is
This is transmitted to a steering pad, for example, an air bag device via a flexible cable of the rotary connector device to ignite an inflator to inflate the air bag.

In the above embodiment, the ventilation holes are formed along the label attaching surface, but the invention is not limited to this. For example, the ventilation holes may be directed from the label attaching surface toward the inside of the housing containing the flexible cable. You may open it.

[0015]

Since the present invention has the above-described function, it has the following effects. (1) That is, in the rotary connector device that electrically connects the steering side and the vehicle body side by the flexible cable housed in the housing in a spiral shape, the housing has ventilation holes on the label sticking surface. When attaching a label to the label, it is possible to prevent air accumulation from occurring between the housing and the label, so that the label attached to the label attaching surface does not have unevenness, and the air expands due to temperature rise and fall. Even if it shrinks, the label does not peel off from the label-applied surface.

(2) Further, in the above invention, since a plurality of recesses are formed on the label sticking surface and the recesses are communicated with each other by the vent holes, it is possible to uniformly remove air pockets from the label sticking surface. At the same time, sink marks due to the shaping of the housing can be prevented.

(3) Further, in the above-mentioned invention, since the ventilation hole is opened to the center side of the housing, the ventilation hole is not visible from the outside of the housing, the appearance is not spoiled, and foreign matter or the like enters from the ventilation hole to the inside. Is hard to enter.
