1 and 2 show preferred embodiments according to the present invention. In the figure, reference numeral 1 denotes a stator housing, which includes a terminal 5 electrically connected to a circuit on the vehicle body side. 2 is a rotor housing,
A connecting pin 21 that is rotatably attached to the stator housing 1 using the attachment 3 and that is connected to a steering handle (not shown), a terminal 6 and an electric wire 61 that are electrically connected to a circuit on the steering handle side. Is equipped with. And the rotor housing 2
The flexible cable 4 is spirally housed in a doughnut-shaped space formed by the stator housing 1 and the stator housing 1. Both ends of the flexible cable 4 are connected to the terminals 5 and 6, respectively.

In the rotor housing 2, the label attaching surface 22 provided on the side facing the steering wheel is lightened to form a plurality of recesses 23. This plurality of recesses 2
3 is formed to prevent so-called "sink" when the rotor housing 2 is injection-molded. Vent holes 24 connect between the recesses 23 formed on the label attaching surface 23. The passage formed by the vent hole 24 opens at the center side of the rotor housing 2, that is, the side where the steering shaft is fitted.

The caution label 7 is attached to the label attaching surface 22 of the rotor housing 2.
The caution label 7 is composed of a resin film or paper with an adhesive applied on the back surface, and notes on handling the rotary connector device are printed on the front surface. Further, the caution label 2 has a tongue piece which has a ring-shaped shape having a diameter substantially the same as the diameter of the rotor housing 2 and is partially notched, and which protrudes from the outer periphery 73 thereof as shown in FIG. 71 is provided. A breaking portion 72 that breaks due to external stress is formed in the middle of the tongue piece 71. The fractured portion 72 is a portion where stress is easily concentrated by perforations or the like.

The tongue piece 71 is attached so as to extend over both the stator housing 1 and the rotor housing 2, and holds the rotational position of the rotor housing 2 with respect to the stator housing 1 at the neutral position. The fracture surface 72 provided on the tongue piece 71 is provided after the rotary connector device is mounted on the vehicle body.
When the rotor housing 2 rotates relative to the stator housing 1 by rotating the steering handle, stress is applied and the rotor housing 2 is broken. At this time, if the tongue 71 is not sufficiently attached to the rotor housing 2, a tensile force is applied from the tongue 71 to the caution label 7, and the caution label 7 may be peeled off. In order to prevent this, in this embodiment, the tongue piece 71 is provided at a position other than the cutout position 74 of the caution label 7 so that the caution label 7 can be used even in the above case.
It is difficult to peel off.

Further, as described above, when the caution label 7 is attached to the rotor housing 2, the space inside each recess 23 communicates with the external space of the connector device, that is, the atmosphere, through the vent hole 24. . Therefore, regardless of whether the ambient temperature rises or falls, the two spaces have the same pressure at all times, and the caution label 7 becomes uneven due to unevenness, and the expansion and contraction of air causes the caution label 7 to adhere to the label. The problem of peeling from the surface 22 does not occur.

The rotary connector device in which the caution label 7 is attached to the rotor housing 2 has, for example, an airbag device (not shown) on the steering handle side.
The other is connected to, for example, an airbag controller (not shown) on the vehicle body side. Thus, for example, when a vehicle has a collision accident, an electric signal from the airbag controller is transmitted to, for example, the airbag device of the steering pad through the flexible cable of the rotary connector device, and the inflator is ignited so that the airbag is ignited. It will be inflated.

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. Further, the breaking portion provided on the tongue piece is not always necessary, and may be omitted when the caution label is made of paper, for example.

【The invention's effect】

(1) Since the rotary connector device according to the present invention has the tongue piece on the outer periphery of the caution label attached to the housing, the existing caution label is used to hold the rotary connector device in the neutral position until it is mounted on the vehicle body. In other words, the rotary connector device does not require a special part for holding the neutral position, and thus the economical value is high. (2) Further, since the caution label has substantially the same diameter as the housing and has the tongue protruding from the outer periphery of the caution label, a sufficient adhesion area of the caution label to the housing can be secured. Further, since the caution label has a ring-shaped shape in which a part is cut out, and the tongue piece is projected to a position other than the cutout position, when external stress is applied to the tongue piece. The caution label is difficult to peel off from the housing. (3) Further, by forming the caution label from paper, the tongue piece is easily broken and the caution label can be manufactured at low cost.
