In a device for detecting mirror position, there is provided a resistor substrate being located coaxially with a nut adjuster for adjusting an angle of incline of a mirror, and a contact member so as to rip the resistor substrate . The contact member slides in pine corresponding to the movement of the nut adjuster while the resistor substrate is fixed to a housing. Thus, as the nut adjuster slides, the contact member slides against the resistor substrate, which results the change of a contact position of the contact member and a long resistance Rl. Consequently, since a voltage level generated at the contact member changes, the angle of incline of the mirror can be determined by detecting this voltage level. Inasmuch as the contact member and the resistor substrate are housed within a sliding block, there is no need for much space to locate the various parts in, and thus the whole device can be configured in a compact manner. In addition, the fact that the resistance R1 is connected to the direct-current power source via resistances R2 and R3 means that the measured voltage level is acquired in the form of an intermediate value of the direct-current power source voltage. Subsequently, it is possible to reduce the influence of noise and other factors so that the mirror angle can be detected with a high degree of accuracy.
