Description of the Related Art For people with disabilities, such as the physically handicapped and the elderly who need nursing care, passenger cars are a powerful means of transportation, while existing mass-market vehicles are developed for healthy people. Therefore, it is very difficult to use. For example,
Passenger cars used by physically handicapped people have a method of loading and unloading a wheelchair together with a rear door that is used for loading and unloading luggage, and the psychological burden of being treated as baggage by a physically handicapped person. In addition, since the person in the car is still seated in a wheelchair, the view and height of a normal person are different, and there is a feeling of resistance to conversation in the car. In addition, even when using an ordinary passenger car, it is necessary to transfer to an ordinary passenger car seat with the help of a caregiver, which imposes a considerable burden on the caregiver and a person with a physical disability. Often the caregiver loses the opportunity to go out. A rotating frame that is horizontally rotatably supported by a pedestal fixed to the floor of a passenger car as a rotating seat that can be transferred to a front seat of a passenger car without a caregiver by a person with a disability in such a wheelchair. And a rotating seat base that is integrated with the rotating frame and is provided with a slide rail that is slidable forward, and a seat body that is fixed to the slide, and a seat is provided outside the passenger car from a seated position during traveling. After horizontally moving the main body, the seat main body was slid to the outside of the vehicle in front and transferred to a wheelchair placed beside the seat main body or from the wheelchair to the seat main body.
