PROBLEM TO BE SOLVED: To provide a tube type collision detection device for a vehicle which can dispose a pressure sensor at a proper position.SOLUTION: A collision detection device 1 for a vehicle has a hollow tube member 2 for detection which is disposed on a vehicle front side of a bumper reinforcement 9 in a bumper 6 of the vehicle, and a pressure sensor 3 for detecting a pressure in the tube member 2 for detection. Based on the result of pressure detection by the pressure sensor 3, a collision of an object with the bumper 6 is detected. The detection device 1 is equipped with a connection tube 4 which is a member having a hollow tube shape and of which one end is so connected to the tube member 2 for detection that hollow parts of both are communicated with each other. The pressure sensor 3 is connected to the other end of the connection tube 4 and detects a pressure in the tube member 2 for detection. |
