PURPOSE:To prevent a car from being brought into contact with an obstacle when driving slowly by installing an antenna for giving forth a signal sound when said car is brought into contact with said obstacle. CONSTITUTION:An attaching member 1 which is attachable to a car body is formed into a disk shape, and can be firmly attached to the body when it is strongly pressed against the body. A flexible antenna 2 is installed on this attaching member 1. The end (iii) of the antenna 2 is made of a soft rubber and its rod body part (iv) is formed into a cylindrical shape with metal band from plates and is freely bendable right and left. The lower end of a wire (v) stretched in the antenna 2 is connected to the terminal of the buzzer (vi) of an operating mechanism 3. Thereby, if the antenna 2 is hit against an obsta cle and bent as in the figure B, the wire (v) is brought into contact with the cylindrical part, causing a current to flow to operate the buzzer (vi). According ly, an obstacle can be sensed immediately before it is brought into contact with a body, preventing a car from being rubbed against an obstacle and scratching its body.
