  By the way, in the conventional front bumper, when an input is applied to the lower part of the front bumper due to a light vehicle collision, the input may be directly transmitted from the bumper to a turn lamp or a fog lamp, and the lamp may be damaged. This seems to be due to the fact that the input to the lower part of the bumper is easily transmitted from the upper edge of the grille opening to the outside of the vehicle, and the lamp is located on this input transmission line.

  The present invention has been made in view of the above-described conventional situation, and an object of the present invention is to provide a vehicle bumper that can prevent in-vehicle components such as a lamp from being damaged during a light vehicle collision.

  The present invention includes a vehicle having a functional opening provided to have a predetermined function, and first and second mounting openings provided to attach at least two vehicle-mounted components to the outside of the functional opening in the vehicle width direction. In the bumper, the first and second mounting openings are arranged side by side, and a bending promoting portion having a concave cross-sectional shape is formed on the vehicle inner side at a boundary portion of the first and second mounting openings. The bend promoting part is arranged so as to substantially coincide with an extension line in the vehicle width direction passing through the upper edge of the functional opening.

  According to the vehicle bumper of the present invention, a bending promoting portion having a concave cross section is formed inside the vehicle at the boundary between the first and second mounting openings of the bumper, and the bending promoting portion is formed on the upper edge of the functional opening. Since the input is applied to the lower part of the bumper due to a light vehicle collision, the input is transmitted from the upper edge of the functional opening to the bending promoting portion, and the bending promoting portion is The lower part of the starting point will fold backward and deform. As a result, it is possible to prevent the input from being directly applied to the in-vehicle component and to prevent the in-vehicle component from being damaged.

The upper and lower grilles 2 and 3 have a schematic structure in which a large number of air intake ports 2b and 3b in a lattice shape are formed in the frame portions 2a and 3a, respectively.

  The aforementioned radiator is disposed on the rear side of the right side portion of the upper and lower grills 2 and 3 when viewed from the front of the vehicle, and a horn 4 is provided on the rear side of the left end of the lower grill 3. It is arranged (see FIG. 2).

  A turn lamp 8 and a fog lamp 9 as vehicle-mounted components are disposed on the left and right outer sides of the lower grill 3 of the front bumper 1 in the vehicle width direction. Since the turn lamp 8 and the fog lamp 9 are symmetrical, the left turn lamp 8 and the fog lamp 9 viewed from the front of the vehicle will be described.

  The turn lamp 8 has a structure in which a lamp bulb 8b is detachably attached to a bottom portion of a lamp body 8a having a generally bowl shape, and a lens 8c is disposed at a front end opening of the lamp body 8a.

  In the fog lamp 9, a lamp bulb 9b is detachably attached to the bottom of a lamp body 9a having a generally bowl shape, and a lens 9c is disposed at a front end opening of the lamp body 9a, and an outer periphery of the lens 9c is disposed on the lens 9c. A surrounding lamp cover 9d is mounted.

  First and second mounting openings 1g and 1h for mounting the turn lamp 8 and fog lamp 9 are formed on the left and right outer sides in the vehicle width direction of the lower grille opening 1f of the front bumper 1, respectively.

  The turn lamp 8 is mounted in the first mounting opening 1g from the front of the vehicle, and is mounted on the bumper body 1a by a claw fitting and fastening member. The fog lamp 9 is mounted in the second mounting opening 1h from the front of the vehicle, and is mounted on the bumper body 1a by a claw fitting and fastening member in the same manner as described above.

  The first and second mounting openings 1g and 1h are arranged side by side so as to be substantially continuous vertically.

  The first mounting opening 1g is formed to have an opening edge 1g 'that is rectangular in the vertical direction, and bulges to form a generally bowl-like shape following the opening edge 1g' so that the turn lamp 8 can be accommodated. And a mounting hole 1j formed at the bottom of the lamp housing 1i.

  The second attachment opening 1h is disposed below the first attachment opening 1g and is formed to extend inward from the first attachment opening 1g.
