    • The present invention relates to a theft preventive apparatus to be attached to an object of theft prevention for detecting a preliminary stealing act by e.g. issuing alarm, and relates also to a radio wave receiving signaling device to be used with the apparatus. Conventionally, there has been a problem of the alarm output means being rendered inoperative when a sudden shock is applied to the theft preventive apparatus for example. According to the present invention, a circuit board (6) of alarm output means (AO) disposed inside a box (2) to be attached to the object of theft prevention is retained to one first side wall portion (2a) of a pair of opposed wall portions (2a), (2c) of the box, and the other side second wall portion (2c) retains a first-kind constituting element (FE) of the alarm output means (AO). A power-supply contact member (CE) formed integrally with the first-kind constituting element (FE) is adapted to contact a first-kind contact (FC) having a contact face extending toward the second wall portion of the circuit board (6). And, the power-supply contact member (CE) is comprised of a coil spring which can expand and contract in the approaching/departing direction of the pair of wall portions (2a), (2c) and which is disposed under a state contracted from its maximally expanded state. Then, the electric contact may be maintained against sudden shock.
