PROBLEM TO BE SOLVED: To provide a door pinching detection system that can improve safety to the door pinching in a railway vehicle.SOLUTION: The door pinching detection system 10 includes: a tape switch 20 that is built into a left side door stop rubber 4L; a door side coupler 30 and a vehicle body side coupler 40 that performs power supply to the tape switch 20 and reception of the electric signal from the tape switch 20 with noncontact; and a controller 50 that determines the occurrence of the door pinching by receiving the electric signal from the tape switch 20. A beam sensor 60 is mounted on upper frame part 5 that is disposed on a contact line where the door stop rubbers 4L and 4R contact mutually and located upper side than the vehicle door 2L, and this beam sensor 60 is connected with the controller 50. The controller 50 is composed to determine the occurrence of the door pinching when receiving the output detection signal that the beam sensor 60 outputs when the signal light is interrupted, or when received the electric signal that the tape switch 20 outputs.
