PROBLEM TO BE SOLVED: To make a roof panel body firmly resist against a load of snow when snowing.SOLUTION: The roof panel 13 of a vehicle body 2 includes the roof panel body 17 constituting a middle part of the roof panel 13 in a width direction of the vehicle body 2, and formed in a convex shape upwardly seen from a front section of the vehicle body 2. When seen from the front section of the vehicle body 2, height of a portion of the roof panel body 17 from an imaginary horizontal line 21 connecting right and left outer ends of the roof panel body 17 is designated y, a position of the portion of the roof panel body 17 from a centerline 18 in the width direction of the vehicle body 2 of the roof panel body 17 to the outer end of the roof panel body 17 is designated as x, and a roof height of the roof panel body 17 from the imaginary horizontal line 21 on the centerline 18 is designated as h. A sectional shape of the roof panel body 17 satisfies a formula, y=-ax+h, provided n=2.01-2.20. |
