A walker collision detector includes a chamber member and a pressure sensor. The chamber member defines a chamber. On a back side of the chamber member, a concave for housing the pressure sensor is formed. The pressure sensor is connected to the chamber member for detecting the pressure in the chamber. The pressure sensor in a housed condition in the concave is connected to the chamber member, and is fixed on a front face of a bumper reinforcement. Therefore, a pressure sensor arrangement space conventionally required for installing the pressure sensor is not required, and cutting work or the like of the bumper reinforcement is not required. As a result, the walker collision detector has an improved installability on a vehicle.
