ABSTRACT:
An alarm device including a sensor having sufficiently high detection sensitivity. The sensor51in the alarm device41is disposed such that a plane M perpendicular to the detection direction P of the sensor 51 is aligned at a specified angle θ with respect to a plane V perpendicular to the sun visor 72 (the lower surface61a), were the specified angle θ should be set to be an approximately mean value of the expected minimum angle γ=0° and the expected maximum angle γ=40° (in this case, θ=20°). In other words, the plane M perpendicular to the detection direction P of the sensor 51 should be aligned at an angle α(α=90°−θ) of less than 90° with respect to the sun visor72(the lower surface61a). The alarm device may be mounted onto a vehicle for preventing the vehicle theft.
