PROBLEM TO BE SOLVED: To provide an under-run protector capable of retaining strength and rigidity while suppressing weight and cost.SOLUTION: An under lamp protector 1 extrusion-molded of an aluminum material and having a closed section formed of an inner face part 12, an outer face part 11, an upper face part 13 and a lower face part 14. The under lamp protector 1 comprises, in a closed section: an upper reinforcing part 21 extending inclined downward from an upper outside joint part 31, in which the upper face part 13 and the outer face part 11 are jointed, to an upper inside joint part 32 provided at the inner face part 12; and a lower reinforcing part 22 extending, in the closed section, from a lower outside coupling part 33, in which the lower face part 14 and the outer face part 11 are jointed, to a lower inside joint part 34 provided at the inner face part 12. A distance L1 between the upper inside joint part 32 and the lower inside joint part 34 is set within a distance L2 between the upper inside joint part 32 and the upper face part 13 and within a distance L3 between the lower inside joint part 34 and the lower face part 14. |
