Abstract
A collision detection device includes a chamber member, a pressure sensor, a collision detection ECU, and a projecting portion. The chamber member is disposed on a vehicle-front side of a bumper reinforcement in a bumper cover and includes a chamber main body having therein a hollow portion. The pressure sensor detects pressure in the hollow portion of the chamber main body. A clearance is formed between the chamber member and a front surface of the bumper reinforcement at least on a part of a rear surface of the chamber main body. The collision detection ECU detects a collision of an object with the bumper cover based on a pressure detection result by the pressure sensor. The projecting portion is provided to project from the rear surface of the chamber main body, and an end of the projecting portion is in contact with the front surface of the bumper reinforcement.
