<p>PURPOSE:To provide a sensor light refractor capable of surely preventing damaging of the flocking part of a brush for clearing the stains stuch on the mirror finished surface of a mirror in the right and left edge parts of the mirror. CONSTITUTION:This sensor light refractor is applied to a device installing a mechanism of detecting the presence or absence of an object by using arbitrary sensor light and has the mirror 1 for reflecting the sensor light, a mounting sheet metal 2 for mounting the mirror 1 and the brush 3 for cleaning the mirror finished surface of the mirror 1 by the reciprocating motion of the flocking part. The sensor light refractor described above has a mirror holder 4 which is mounted from the rear surface direction of the mounting sheet metal 2 in the state of adhering the mirror 1 to the front surface part of the mounting sheet metal 2, has a form of projecting its top edge in the front surface direction from the mirror finished surface of the mirror 1 in such mounted state and installing a pair of right and left edge guides 41a, 41b for preventing contact of the flocking part of the brush 3 with the right and left edge parts of the mirror 1 at the time of cleaning the mirror finished surface or the mirror 1.</p> |
