By the way, in such a rotating seat in which the passenger seat can take a forward state and a facing state (rearward state), when the passenger seat is placed in the facing state, a vehicle such as an air conditioner is mounted. There is a demand for enabling the engine to operate to increase the comfort of the device by activating the device. On the other hand, it is necessary to prevent the vehicle from traveling while the passenger seat is facing or rotating.

[0004] The above-mentioned conventional sheet rotating device is
If the driver's seat is not in the seated position, the passenger seat cannot be in the seated state, and if the passenger's seat is not in the forward position, the driver's seat cannot be in the forward position. In addition, the driver's seat cannot be turned forward to prevent the traveling movement of the automobile.

However, even if the driver's seat is in the opposite seating state in which the driver's seat cannot be turned forward, for example, if the shift lever is erroneously operated to the traveling range, the vehicle may run without the driver's seat being turned forward. There is a disadvantage that the traveling movement of the automobile when the passenger seat is in the seated state cannot be reliably prevented.

In particular, in an automatic transmission, the shift operation of the shift lever is different from that in a manual transmission, and the shift operation to each shift range can be easily performed without performing a clutch operation. , The neutral range (N range) and the traveling range (D range) are arranged adjacent to each other, so that the shift lever is easily erroneously operated from the neutral range to the traveling range. For this reason, when a rotating seat device is employed in an automobile equipped with such an automatic transmission, an erroneous operation of the shift lever to the travel range is performed when the front passenger seat in the rotating seat device is in a seated state. If a car is driven, it must be prevented.

Embodiments of the present invention will be described below in detail with reference to the drawings. This example is an example applied to an automatic vehicle. 1 is a passenger seat, a seat cushion 2
A rotary table 4 is attached and fixed below the seat cushion 2. On the lower surface of the rotary table 4, an annular engaging member 5 having a hat-shaped cross section is fixedly mounted, and the engaging member 5 is rotatably slidable on an annular rail member 7 fixedly mounted on a rotating base 6. The rotation table 4 is rotatable with respect to the rotation base 6 by the combination.

Further, engaging members 11A and 11B extending in the longitudinal direction of the vehicle body are fixed below the rotating base 6, and the engaging members 11A and 11B
The front seat 1 is slidable in the vehicle longitudinal direction by slidably engaging the rail members 14 attached via the members 3 and 13.

The rotation base 6 is provided with a sheet position detection switch 21.
Is turned ON or OFF depending on whether or not it comes into contact with the protruding member 22 which is fixed to the engaging member 5 and protrudes downward, and detects the facing state of the passenger seat 1.

The engaging member 5 has an extension 11a extending inwardly of the vehicle body.
