  In recent years, the space for installing an air outlet at the center of the rear end panel in the vehicle width direction has disappeared due to needs such as the enlargement of the cargo compartment and the arrangement of spare tires under the cargo compartment. For this reason, it may be difficult to install the air outlet at a front position (substantially central position in the vehicle width direction) of the license plate installation portion. In this case, since the air outlet is disposed at a position shifted from the installation portion of the license plate, if a rib covering the air outlet is provided on the back surface of the bumper face, sink marks generated when the bumper face is formed are formed. May appear on the bumper face where it is easily visible from the outside.

  Therefore, the present invention is intended to provide a vehicular bumper in which the air outlet can be arranged at a position deviated from the approximate center in the vehicle width direction while suppressing the deterioration of the design of the bumper face.

The vehicle bumper according to the present invention employs the following configuration in order to solve the above problems.
That is, the vehicle bumper according to the present invention includes a resin bumper face (for example, the rear bumper face 30 of the embodiment) that covers the outside of the vehicle body, and the bumper face has a stepped depression with respect to the design surface. It has a step part (for example, step part 30Lb of the embodiment) that is covered by a lower corner part of the opening / closing member (for example, tail gate 37 of the embodiment) arranged outside, and confronts the back surface of the step part. A vehicle body side air outlet (for example, the air outlet 39 of the embodiment) is disposed, and a rib (for example, the rib 70 of the embodiment) that covers the outside of the vehicle body side air outlet protrudes from the back surface of the stepped portion. It is characterized by.

  With the above configuration, the air outlet can be arranged at a position deviating from the substantially central position in the vehicle width direction at the rear of the vehicle. Even if sink marks may occur outside the bumper face step due to the ribs that cover the outside of the air outlet, the step is covered by an opening / closing member arranged outside the vehicle body. Can be suppressed.

The rib may protrude from a bent ridge line (for example, a bent ridge line 71 of the embodiment) of the stepped portion.
In this case, since the rib protrudes from the bent ridge line portion of the stepped portion, even if the sink marks may be in contact with the eyes from the outside with the opening and closing member open, unlike when there is a sink on the flat surface, No sink marks stand out from the outside.

The bumper face includes a pair of side face blocks (for example, the side face blocks 30L and 30R in the embodiment) arranged on the left and right in the vehicle width direction and a center face arranged between the pair of side face blocks. A block (for example, the central face block 30C of the embodiment), and at least one of the side face blocks has the stepped portion and the rib, and the bumper face on the inner edge in the vehicle width direction. A boundary engaging portion (for example, the boundary engaging portion 41 of the embodiment) that bulges to the back surface side and engages with the central face block is provided, and the rib is a laterally extending portion that extends in a substantially horizontal direction ( For example, the laterally extending portion 70a) of the embodiment, and the longitudinally extending portion (for example, the longitudinally extending portion 70b of the embodiment) extending in the vertical direction from the end of the laterally extending portion on the vehicle width direction outside, The boundary engaging portion extends in the vertical direction at the edge of the side face block, and forms a substantially U-shaped wall that covers the outside of the air outlet together with the rib. Anyway.
In this case, the rib provided in the step portion of the side face block covers the outside of the air outlet together with the boundary engaging portion extending in the vertical direction, and prevents rainwater and the like from entering the air outlet. Further, the boundary engaging portion functions to increase the rigidity of the inner edge in the vehicle width direction of the side face block in addition to the function of preventing rainwater and the like from entering the air outlet. Therefore, when this configuration is adopted, the appearance of the boundary portion between the side face block and the central face block can be kept good, and the attaching / detaching operation of the central face block can be suitably performed.

The boundary engaging portion has a bent wall (for example, the bent wall 20 of the embodiment) that is recessed toward the back surface side of the bumper face and extends in the vertical direction, and is formed on the back portion of the bent wall. An engagement piece (for example, the engagement piece 24 of the embodiment) projecting from the edge of the central face block can be engaged with the groove (for example, the engagement groove 22 of the embodiment). May be.
In this case, since the bent wall of the boundary engaging portion extends in the vertical direction, the rigidity of the edge on the inner side in the vehicle width direction of the side face block can be further increased. Moreover, since the engagement piece of the center face block is engaged with the engagement groove on the back of the bent wall, both the center face block and the side face block can be stably maintained in the engaged state when the center face block and the side face block are assembled. it can.

The boundary engaging portion is formed with the bent wall at a portion that forms the substantially U-shaped wall together with the rib, and a concave wall having a concave cross section continuous to the bent wall below the bent wall ( For example, the concave wall 21) of the embodiment may be formed, and the lower end of the concave wall may be fastened and fixed to the lower end of the central face block.
In this case, the edge of the side face block on the inner side in the vehicle width direction is enhanced in rigidity by the bent wall on the upper side and the concave wall continuous to the bent wall, and the lower end of the concave wall is fastened to the lower end of the central face block. The For this reason, the center face block and the side face block can be more stably maintained in the engaged state.

A bent piece (for example, the bent piece 25 of the embodiment) is inserted into the inside of the concave wall of the side face block from the surface side of the side face block at the outer end in the vehicle width direction of the central face block. ) Is extended, and the bending piece is attached with a fixing clip (for example, the fixing clip 47 of the embodiment) for fixing the central face block to the vehicle body, and the bottom of the concave wall has the above-mentioned A clip insertion hole (for example, the clip insertion hole 46 of the embodiment) for projecting the fixing clip toward the vehicle body may be formed.
In this case, when the central face block is fixed to the vehicle body via the fixing clip, the concave wall of the side face block is sandwiched between the bent piece of the central face block to which the fixing clip is attached and the vehicle body. For this reason, the center face block and the side face block can be more stably maintained in the engaged state.

A folded flange portion having a substantially U-shaped cross section (for example, the folded flange portion 21a of the embodiment) may be continuously formed in the up-down direction on the inner edge of the concave wall in the vehicle width direction.
In this case, the vertical and horizontal rigidity of the concave wall of the side face block can be increased by the folded flange having a substantially U-shaped cross section. Therefore, when this configuration is adopted, the detachment of the central face block with respect to the side face block can be stabilized.

A fastening seat (for example, the fastening seat 60 of the embodiment) having a height substantially the same as the bottom surface of the concave wall of the side face block and the vehicle body direction is located above the extended position of the bent piece of the central face block. The fastening seat may be fixed to the vehicle body by a fastening member (for example, the bolt 55 of the embodiment).
In this case, with the center face block sandwiching the inner edge in the vehicle width direction of the side face block, the outer edge in the vehicle width direction of the center face block is firmly fixed to the vehicle body by the fixing clip and the fastening member. be able to.

The side face block has a rear wall facing the rear surface of the vehicle body (for example, the rear wall w1 of the embodiment), and a side wall facing the rear side surface of the vehicle body (for example, the side wall w2 of the embodiment), A metal bracket (for example, the bracket 27 of the embodiment) that also serves as a reinforcement of the side wall is attached to the side wall, and the rear wall has a plurality of fastening members (for example, The side wall may be fixed to the side surface of the vehicle body via the bracket.
In this case, the side face block can be firmly fixed to the vehicle body.

A concave groove (for example, the concave groove 73 in the embodiment) that opens in a substantially V shape toward the vehicle outer side may be provided in the abutting portion on the vehicle outer side of the side face block and the central face block. .
In this case, when painting from the outer side of the side face block and the central face block with the side face block and the central face block assembled to the vehicle body, the paint sprayed from the painting gun is applied to the side face block. It is possible to reach a deep part of the butt portion between the block and the central face block. Therefore, the appearance after painting of the side face block and the central face block can be improved.

A cylindrical nut member (for example, the nut member 29 of the embodiment) for fastening an eyebolt is fixed to the rear lower surface of the vehicle body, and an opening of the nut member (on the concave wall of the side face block ( For example, you may make it provide the nut cover part (for example, nut cover part 32 of embodiment) surrounding the circumference | surroundings of the vicinity part of the opening 29a) of embodiment.
In this case, even if the nut member is installed in the vicinity of the gap between the side face block and the central face block where water droplets or the like are likely to enter from the outside, the nut cover portion surrounds the vicinity of the opening of the nut member, Infiltration of water droplets or the like into the opening can be suppressed.

The central face block and the side face block are provided with a U-shaped cross-section portion (for example, the U-shaped cross-section portion C1 of the embodiment) whose longitudinal section is convex toward the rear side of the vehicle body. The concave wall may be arranged inside the cross section so as to support the upper and lower walls of the U-shaped cross section.
In this case, the U-shaped cross section of the center face block and the side face block is reinforced by the concave wall of the side face block extending in the vertical direction, and the rigidity and strength of the U-shaped cross section are kept high. Can do.
