Claims (1)

[Scope of utility model registration request] First, second, and third solar radiation sensors are disposed at appropriate positions on the vehicle body in a substantially vertical direction, and a portion of the light-receiving surface of the second solar radiation sensor and the third solar radiation sensor is covered to cover the respective light-receiving ranges. is limited to approximately 180°, and the boundaries separating the light receiving range and non-light receiving range are inclined with respect to the longitudinal direction of the vehicle body so as to intersect with each other at a predetermined angle, and the solar radiation direction is determined based on the presence or absence of light reception by each solar radiation sensor. "front", "back", "left"
, a solar radiation direction detection device for an air conditioner for an automobile, characterized in that the direction is determined to be “right”.
