And assort with the whole coach sculpt. With the development of our vehicle technology, the domestic vehicle factory has already adopted the outer turning service door. It has much more predominance. The outer turning service door is the door which has no tram road and parallel move out of the coach, the door was supported by the circumrotate arm. By the rotation of the circumrotate axes, the door is moving close to the parallel move. Thus this door is called translation door.This paper introduces the design of the door of a medium-sized passenger car which permit a disable and sick wheel chair . Include the design of the outer turning service door and the the swing door. Analyzed the structure and operating principles of the outer turning service door and the swing door, determined the size of its parts and major components of the models and installation. Discussed the development of the vehicle annex industry. Application in this design the CAD software create in front and back passenger's door.KEY WORDS: outer turning service door，swing door，CAD
