PROBLEM TO BE SOLVED: To provide a sun visor device for vehicle of simple constitution capable of easily estimating the eye position of an occupant and performing an appropriate light blocking control using the estimated eye position. SOLUTION: Assume that the position of the sun visor main body is adjusted by the occupant when incident light having an incident angleθ1 has entered the vehicle compartment. Then, a straight line L1 is obtained that passes through the distal end position S1 of the moved sun visor main body and is inclined by the same angle as the incident angleθ1. At this time, the intersection between a straight line Y1, which passes through an eye position PO of an average sized person and extends along the vertical direction of the vehicle, and the straight line L1 is estimated as an eye position P1 of the occupant. Thereafter, a light blocking control is performed in accordance with the estimated eye position P1. COPYRIGHT: (C)2006,JPO&NCIPI
