Abstract

PROBLEM TO BE SOLVED: To provide a rear bumper mounting structure capable of satisfactorily holding the quality of appearance of an opening peripheral edge even when a rear hatch gate is opened and reducing such a possibility that a peeling of a spot welding occurs by distributing a load input. SOLUTION: An in-member reinforcing member 13 installed across a rear end cross panel 12b and a rear panel 12a is installed in a rear end cross member 12. Bolt through-holes 13e are formed in the in-member reinforcing member 13. A plurality of stud bolts 18 are insert-formed in resin bumper facia member 14 integrally with each other. Also, nut members 19 are screwed to the stud bolts 18 in the rear end cross member 12. Thus, a rear wall surface part mounting piece 13b and a rear panel 12a can be tightened to the bumper facia member 14.
