In order to block such incident light, a sun visor is generally installed in the passenger compartment of an automobile. The sun visor is usually an L-shaped support shaft that is rotatably provided around the axis in the ceiling of the vehicle interior, and a light shield that is rotatably supported around a horizontal portion (horizontal axis) of the support shaft. It is composed of a board. An insertion hole is bored in the axial center portion of the support shaft in the longitudinal direction, and a harness, which is a cord wire, is often inserted in the insertion hole. This harness is for supplying electric power to the light bulb attached to the shading plate. By doing so, it is convenient to get the lighting at hand at night, and the harness is not exposed to the outside, It looks good.

By the way, in the conventional support shaft structure as described above, since the insertion hole is provided penetrating the axial center portion of the support shaft bent in the L shape in the longitudinal direction, the harness is provided in the insertion hole. It was very difficult to insert the harness into the sun visor, and therefore, it took a lot of time to attach the harness to the sun visor in the process of assembling the sun visor.

Therefore, as disclosed in, for example, Japanese Utility Model Publication No. 59-34506, a fitting groove is formed in the outer peripheral portion of the support shaft in the longitudinal direction, and a harness is fitted in the groove. Those that are designed to be included are disclosed. The use of such a support shaft simplifies the manufacture of the support shaft itself and facilitates the harness mounting operation.

[0005]

[Problems to be solved by the device]

 Incidentally, in the support shaft disclosed in Japanese Utility Model Publication No. 59-34506, as can be seen from the drawings attached to the specification, the fitting groove into which the harness is fitted is a mere U-shaped groove and the constricted portion is Since it does not exist and the fitting groove is formed inside the bent part of the elbow part of the support shaft, if tension is applied to the harness while it is fitted in the fitting groove, it is extremely easy to fit the harness. There is the inconvenience of being out of the groove. Therefore, in order to avoid such inconvenience, the elbow is covered with a synthetic resin tube after the harness is installed in the fitting groove, and the tube is heat-shrinked to close the fitting groove opening. Is being done.

However, if a tube made of synthetic resin is mounted on the elbow portion of the support shaft, the material cost increases due to this tube, and the number of assembly steps increases due to the tube mounting operation and heat shrinking operation. A new problem is raised.

The present invention has been made in order to solve the above-mentioned problems, does not increase the material cost, allows the mounting operation of the harness on the support shaft to be performed very easily, and It is an object of the present invention to provide a support shaft structure for an automobile visor that does not easily come off once the harness is attached to the support shaft.

[Effect of device]

 As described above, the support shaft structure of the automobile sun visor of the present invention has a vertical shaft with the support shaft attached to the vehicle body and a horizontal shaft that pivotally supports the light shield plate integrally connected to the vertical shaft at the elbow portion. The vertical axis and the horizontal axis are formed with an insertion hole communicating with each other and through which the harness is inserted in the respective longitudinal directions. At least one of the vertical axis and the horizontal axis is connected to the outside through the insertion hole. A long groove communicating with the elbow portion is formed, and the long groove is positioned so as to pass through the outer edge portion of the elbow portion.

Therefore, even though the support shaft is formed by bending the vertical shaft and the horizontal shaft, when inserting the harness into the insertion hole, it is easy to push the harness through the insertion groove into the insertion hole. The harness can be attached to the insertion hole of the shaft having the long groove.

Even if the long groove is not formed in the other shaft, the long groove extends to the outer edge portion of the elbow portion and is opened to the outside, so that from this portion, the harness is inserted into the insertion hole of the other shaft. It is easy to insert the harness, and after all, even if the support shaft has a bent elbow portion, the harness can be mounted in the insertion hole very easily.

Further, since the long groove is formed not on the inner edge portion of the elbow portion but on the outer edge portion thereof, even if tension is applied to the harness with the harness attached to the insertion hole, the harness is not affected by the long groove of the insertion hole. It is pressed in the direction of the wall surface facing the hole, and it is convenient because it never comes out of the long groove.

Further, if the groove width of the long groove is formed so as to gradually increase from the insertion hole to the outside, it is possible to perform the mounting operation to the insertion hole of the harness from the opening of the wide groove opened to the outside. The harness wearing operation becomes easy. Once the harness is installed in the insertion hole, the groove width on the insertion hole side of the long groove is set to be smaller than the diameter of the insertion hole, and thus the harness is narrowed in the direction from the insertion hole to the long groove. It is advantageous that the movement is effectively suppressed and the harness can be stably held in the insertion hole.
