Abstract

A vehicle rear bumper includes a rear bumper face. The rear bumper face includes right and left side face blocks and a middle face block. An outer edge part in the vehicle width direction of the middle face block is fastened and fixed attachably and detachably to the right and left side face blocks. The middle face block has a lower flange that extends in a vehicle body frontward direction from a lower end of a block main body part. Each of right and left edge parts of the lower flange is fastened and fixed to a lower surface of the side face block. In the lower flange, an extension length to the vehicle body frontward direction and a maximum thickness in a vertical direction are gradually increased from a middle region in the vehicle width direction toward a fastening fixation part.

First claim

What is claimed is:

1. A vehicle rear bumper, comprising
a rear bumper face that is arranged at a vehicle rear part,
wherein the rear bumper face comprises: a pair of right and left side face blocks that are arranged at an outer position in a vehicle width direction; and a middle face block that is arranged at a middle position in the vehicle width direction,
an outer edge part in the vehicle width direction of the middle face block is fastened and fixed attachably and detachably to the right and left side face blocks,
the middle face block has a lower flange that extends in a vehicle body frontward direction from a lower end of a block main body part,
each of right and left edge parts of the lower flange is fastened and fixed to a lower surface of corresponding one of the right and left side face blocks, and
the lower flange is formed such that an extension length to the vehicle body frontward direction and a maximum thickness in a vertical direction are gradually increased from a middle region in the vehicle width direction toward a fastening fixation part with the side face block.

2. The vehicle rear bumper according to claim 1 ,
wherein an end edge on a vehicle body frontward side of the lower flange is formed such that a shape is changed in an arc form from a middle region in the vehicle width direction toward the fastening fixation part side.

3. The vehicle rear bumper according to claim 1 ,
wherein the maximum thickness of the lower flange is increased at a surface on an opposite side of an overlapped surface with the side face block.

4. The vehicle rear bumper according to claim 1 ,
wherein the lower flange comprises:
a rear end raised part that expands downward along a side at a vehicle body rearward position;
a front edge rib that expands downward along a side at a vehicle body frontward position in an outer region in the vehicle width direction;
an insertion hole which is formed in an outer region in the vehicle width direction and through which a fastening member is inserted;
an annular rib that expands downward so as to surround a circumferential area of the insertion hole; and
a plurality of radial ribs that expand downward so as to extend from the annular rib in a radial direction, and
the radial rib that is arranged closer to a middle position in the vehicle width direction than the annular rib of the lower flange is formed so as to continue to and form a blunt angle with any one of the front edge rib and the rear end raised part.

5. The vehicle rear bumper according to claim 4 ,
wherein the lower flange further comprises a side edge rib that expands downward along an outer side in the vehicle width direction and that is connected to the front edge rib,
two or more of the radial ribs are arranged at a position that is separated outward in the vehicle width direction across the annular rib from an injection gate trace that is positioned in a middle region in the vehicle width direction of the lower flange, and
the two or more of the radial ribs are connected to the side edge rib.

6. The vehicle rear bumper according to claim 1 ,
wherein an upper edge section of the block main body part of the middle face block has a step portion that is recessed in a step form to a vehicle body frontward side and that accepts a lower end of a tail gate at a vehicle body rear part that is openable and closable in a flip-up manner, and
a fastening hole through which a fastening member for vehicle body fixation is inserted and a recess part that is formed by a circumferential edge part of the fastening hole being recessed to the vehicle body frontward side and that accepts a head part of the fastening member are formed on the step portion.
