PROBLEM TO BE SOLVED: To secure necessary stiffness under normal operation while effectively mitigating impact which a collision object receives in a collision. SOLUTION: Tempered glass 12 supports an upper wall part 20A of a cowl upper panel 20 having a lower end edge part 26A of a window shield glass 26. Consequently, when the collision object such as a head part of a pedestrian gets into contact with a part adjacent to the lower end edge part 26A of the window shield glass 26 and the upper wall part 20A of the cowl upper panel 20 deforms to inside of a vehicle body and load greater than a designated value acts on the tempered glass 12, the tempered glass 12 instantaneously breaks into fine pieces over whole surface by action of a residual compression stress layer formed on a surface thereof.
