PROBLEM TO BE SOLVED: To solve a problem of enlarging an interval between a center mirror and side mirrors for preventing the interference therebetween. SOLUTION: An approximately V-shaped stop part 40b1 is provided to frontward move the center mirror 70 by a distance of the depth of the stop part, so that the center mirror 70 can be moved in the width direction without interference between the center mirror 70 and the side mirrors 80 in the slide part 40a. On the other hand, the shape of runners 50 and 55 is formed into an approximately U shape in a side view and the runners are vertically projectingly disposed from the upper/lower ends of the center mirror by a predetermined distance, so that the center mirror can be slid without any interference of the runners 50 and 55 with the side mirror 80.
