However, the control target which is remotely operated by operating the steering switch device for a vehicle has conventionally been an automatic constant-speed traveling device or an AV device. There has been a demand that a device such as a navigator device also wants to be remotely controlled using a vehicle steering switch device. If the configuration is such that one operation knob operates only one switch, as in the above-described related art, When a large number of operation knobs are required and the steering switch device is to be mounted in a limited space adjacent to the steering wheel of the vehicle, it is necessary to reduce the shape of the operation knob. Therefore, not only the operability of the operation knob is deteriorated, but also the risk of erroneous operation has occurred.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. In a vehicle steering switch device having a plurality of operation knobs and provided adjacent to a steering wheel of a vehicle, a plurality of switches are operated by one operation knob. It is an object of the present invention to provide a steering switch device for a vehicle in which the number of operation knobs is reduced, the operability of the operation knobs is reduced, and the risk of erroneous operation is reduced. Things.

Embodiments of the present invention will be described with reference to the accompanying drawings. The configuration indicated by the symbol 1 in the drawing is a steering switch device 1, which is provided adjacent to the steering wheel 2 of the vehicle as shown in FIG. The steering switch device 1 is used for remotely operating an automatic constant-speed traveling device, an AV device, a telephone hands-free device, and a navigator device by pushing and operating the operation knobs 11, 12, and 13 while holding the steering wheel 1. It is a switch device. In the apparatus shown in FIG. 1, an automatic constant-speed traveling device and a steering switch device 1 for mounting a navigator are mounted on the right side, and a steering switch device 1 for an AV device and a telephone hands-free device is mounted on the left side. ing. However, the left and right steering switch devices 1 have the same configuration, and the same configuration is indicated by the same symbol.

The steering switch device 1 is provided with three operation knobs 11, 12, and 13 on the surface of a case 10. The operation knobs 11, 12, and 13 have an appearance similar to a knob used for a tumbler switch, and include a first operation position 11u, 12u, 13u, a second operation position 11d, 12d, 13d, and a third operation position, respectively. Position 11o, 12
o, 13o. 1st operation position 11u, 12
u and 13u are positions operated in the direction indicated by the arrow U in FIG. 2, and the second operation positions 11d, 12d and 13d are
This is the position to be operated in the direction indicated by arrow D in FIG. The third operation positions 11o, 12o, and 13o are indicated by arrows O in FIG.
This is the position to be operated in the direction indicated by.

Then, the first operation positions 11u, 12
As shown in FIG. 3, a first switch 14 which is operated by pushing the first operation positions 11u, 12u, 13u in the direction of arrow U is provided inside the u, 13u, and the second operation position. Inside 11d, 12d and 13d,
As shown in FIG. 3, the second operation positions 11d, 12d, 13
There is a second switch 15 that is operated by pushing d in the direction of arrow D.

Further, inside the third operation positions 11o, 12o, 13o located at the center of the operation knobs 11, 12, 13:
