<p>PROBLEM TO BE SOLVED: To provide an automatic flasher which can suppress incident light into an optical sensor from the horizontal direction.SOLUTION: Power feeding from a power supply to a load is turned on/off according to output of an optical sensor generating output according to an incident light flux. Also, a housing 5 is provided which accommodates the optical sensor and which is fixed on a wall surface with a rear surface facing the wall surface. The housing 5 has: a window body 53 which allows light from front oblique lower side to pass to the optical sensor; and a cover 54 as a covering part for covering at least a part of the window body 53 when viewed from a direction orthogonal to the wall surface on which the housing 5 is fixed. Incident light such as headlight from the horizontal direction into the optical sensor is suppressed by the cover 54.</p> |
