To do. At this time, the rotation side terminal 159 of the flat cable 149 is fastened and fixed to the rotor housing 131 together with the code cover 157 with the screw 158, and the terminal portion of the rotation side terminal 159 is exposed inside the code cover 157. The rotor housing 131 is rotatably coupled to the stator housing 129 by an attachment 167.

The switch mounting portion 11B of the base 3B,
Switch body 41 of lever switch 5B, 7B on 13B
When B and 43B are fitted, the switch bodies 41B and 43 are
The female connector portion provided at B is the terminal tongue piece 141,
143 is fitted, and the terminal portions on the switch bodies 41B and 43B side are brought into contact with the terminal portions 33B and 35B with a predetermined contact pressure.

Therefore, in the present embodiment as well, the conductor portion 29B on the stator housing 129 can electrically connect between the left and right lever switches 5B and 7B, and the same operational effect as that of the first embodiment can be obtained. You can

Further, in this embodiment, since the conductor portion 29B is provided on the stator housing 129 by plating,
No special member such as a printed wiring board is required, the number of parts can be reduced, and assembly and parts management can be easily performed.

By providing the conductor portion 29B by plating, the original shape of the stator housing 129 can be freely set, and the shape of the stator housing 129 is not restricted by the conductor portion 29B. The housing 129 itself can be made compact.

The conventional insert-molded terminal has a high terminal cost and is therefore expensive as a whole, but the stator housing 129 has a conductor portion 29B.
In the case of integrally forming by plating, the cost of the conductor portion 29B can be reduced, so that the cost can be reduced. Further, when the stator housing 129 is injection-molded, it is not necessary to support or cut the terminal, and the resin molding process of the stator housing 129 can be simplified.

The sliding sheet 145 is provided to reduce the friction of the flat cable 149.
The conductor sheet 29B can be covered with the slide sheet 145. By also using the slide sheet 145 as a cover of the conductor portion 29B, an external member may come into contact with the conductor portion 29B to cause a short circuit or dust accumulation. A special cover for prevention is unnecessary, and the number of parts can be reduced also from this point.

Further, in the present embodiment, since it is not necessary to perform wiring or dispose a printed wiring board, there is no increase in the number of parts and thickness, and it is possible to place the wiring in a narrow space as a whole.

It is also possible to provide a conductor portion 29B on the lower surface side of the stator housing 129.
