  However, in the bumper mounting structure disclosed in Patent Document 1, since the first clip is provided at the back of the recess, it is difficult to visually recognize the position at the time of mounting work, and the clips are temporarily aligned. There is a problem that it is difficult to smoothly install the bumper.

  Then, an object of this invention is to obtain the bumper attachment structure which can perform attachment operation | work more smoothly.

  The present invention provides a bumper mounting structure for mounting a bumper so as to cover the recess using a bracket provided in the recess formed on the surface of the vehicle body, from the opening side position of the recess toward the back side position. By providing a slider supported by the bracket so as to be slidable and moving the slider holding the bumper at the opening side position toward the back side position, the bumper is moved and guided toward the predetermined mounting position. The most important feature is what has been done.

  According to the present invention, a bumper is first held by the slider while visually recognizing the slider disposed on the opening side of the recess, and then the slider is pushed toward the back of the recess together with the bumper. Therefore, the bumper can be mounted more smoothly than before.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a side view of a front portion of a vehicle with a bumper mounted thereon, FIG. 2 is a cross-sectional view of the bumper mounting structure (cross-sectional view taken along the line AA in FIG. 1), and FIG. These are views of the slider of the bumper mounting structure as seen from each direction, where (a) is a side view, (b) is a plan view, (c) is a rear view, and FIG. FIG. 6 is a sectional view of the bumper mounting structure, showing a state where the slider is in the opening side position, and FIG. 7 is a perspective view showing a state where the slider is in the opening side position visible from the outside. is there.

  A recess 5 is formed in the lower edge portion of the front fender panel 1 made of a steel plate or the like, and a bumper 2 made of resin or the like is provided so as to cover the recess 5 using the bracket 3 provided in the recess 5. It is attached. The recessed portion 5 is a region recessed inward from the outer surface of the vehicle body. In the present embodiment, the recessed portion 5 is formed by bending the front fender panel 1 in a step shape. In the present embodiment, as shown in FIG. 2, when the bumper 2 is attached, the outer surface of the outer wall 2a of the bumper 2 and the outer surface of the front fender panel 1 are connected. Is not limited to such an embodiment.

  The bracket 3 includes a clip portion 3c, and the bracket 3 is fixed to the front fender panel 1 by inserting the clip portion 3c into a through hole (not shown) provided in the back wall portion of the recess 5. It is like that. Note that it is preferable that the bracket 3 is arranged not only at one place but also at a plurality of places along the lower edge of the front fender panel 1 in the recess 5 so that the bumper 2 can be held more stably.

  The bracket 3 includes a back wall portion 3 a disposed on the back side of the recess 5, and a guide wall portion 3 f that protrudes from the back wall portion 3 a toward the opening side of the recess 5.

  A rectangular cutout is formed in a part of the guide wall portion 3f in a plan view, and the substantially rectangular plate-like slider 4 is fitted into the cutout.

  The slider 4 functions as a holder that holds the bumper 2. In the present embodiment, the engagement protrusions 4b and 4c are provided on the upper surface of the slider 4, while the engagement recess (through hole) 2c is provided in the upper wall 2b of the bumper 2, and the engagement protrusion 4b is formed in the engagement recess 2c. The holding position of the bumper 2 relative to the slider 4 is defined by inserting and bringing the engaging protrusion 4c into contact with the outer edge of the upper wall 2b.

  The slider 4 is supported by the bracket 3 so as to be slidable between the opening side position and the back side position of the recess 5. In the present embodiment, elongated protrusions 4e are provided on the pair of side surfaces of the substrate portion 4d of the slider 4, while grooves 3e are formed on the side surfaces of the notches formed in the guide wall portion 3f of the bracket 3, and the protrusions 4e extend along the grooves 3e. To be guided. Here, since the groove 3e is provided so as to be oriented in a direction substantially orthogonal to the outer surface of the front fender panel 1 in a state where the bracket 3 is mounted in the recess 5, the extension of the groove 3e The slider 4 guided along the direction can move between the opening side position and the back side position of the recess 5.

  However, to prevent the slider 4 from coming out of the recess 5, the bracket 3 and the slider 4 allow the slider 4 to move from the opening side to the back side, but prevent the movement from the back side to the opening side. A mechanism is provided. Specifically, a plurality of notches 4f extending in the direction perpendicular to the moving direction of the slider 4 and opening downward and toward the opening side are continuously provided along the moving direction of the slider 4 on the lower surface of the slider 4 (arm 4a). On the other hand, a cantilever-shaped arm 3b extending along the lower surface of the slider 4 is projected from the back wall 3a of the bracket 3, and the arm 3b is notched by extending upward and toward the back. A claw portion 3d that engages with 4f is provided, and when the slider 4 tries to move to the opening side, the claw portion 3d and the notch 4f are locked to restrict the movement, and conversely, the slider 4 tries to move to the back side. Then, the engagement between the claw portion 3d and the notch 4f is released so that the slider 4 can move.

  In the present embodiment, the bracket 3 is provided with a stopper 3g for restricting the movement of the slider 4 to the back side of the recess 5 in order to suppress excessive pushing of the slider 4.

  Further, in the present embodiment, as the slider 4 moves toward the back side of the recess 5, the portion where the slider 4 holds the bumper 2 is moved upward, so that the bumper 2 forms the upper wall portion of the recess 5. I try to hit one. Specifically, the slider 4 is provided with a cantilever-like arm 4 a that can move up and down from the back side of the recess 5 to the opening side, and the arm 4 a is pushed up by the elastic force of the arm 3 b of the bracket 3. Further, the thickness of the arm 4a is gradually increased from the back side of the recess 5 toward the opening side (that is, from the base side to the tip side of the arm 4a). By doing so, as the slider 4 moves to the back side of the recess 5, the arm 4b of the slider 4 is pushed upward by the arm 3b of the bracket 3, and through the engaging protrusion 4b provided at the tip of the arm 4a. The bumper 2 is pushed upward.

  6 and 7, when the slider 4 is positioned on the opening side, at least the tip of the slider 4, more preferably a structure for engaging the bumper 2 (engagement in this embodiment). The protrusion 4b) is configured to be visible with a line of sight obliquely from above (a line of sight from a standing posture of the worker or a slightly bent waist when the bumper 2 is attached). Even in this state, it is preferable that the claw portion 3d and the notch 4f are locked so that the slider 4 does not come out of the recess 5.

  In the above-described embodiment, when the bumper 2 is attached to the vehicle body side, the bracket 3 is first attached to the recess 5, and the slider 4 is attached to the bracket 3, and the slider 4 is disposed on the opening side.

  At this time, as shown in FIGS. 6 and 7, the operator can visually recognize at least the front end portion of the slider 4 disposed on the opening side with a line of sight obliquely from above. Therefore, the operator can place the bumper 2 on the predetermined position more securely and temporarily hold it on the slider 4 while visually checking the slider 4.

  Next, the operator pushes the bumper 2 toward the back side of the recess 5 to move the slider 4 to the back side of the recess 5 along a predetermined path, thereby moving the bumper 2 toward a predetermined mounting position. Can be made.

  That is, according to the present embodiment, the bumper 2 can be positioned with respect to the vehicle body side member very easily, and the mounting work of the bumper 2 can be performed more smoothly than in the past.

  Furthermore, according to the present embodiment, since the stopper 3g for restricting the movement of the slider 4 to the back side of the recess 5 is provided, excessive pressing of the bumper 2 can be suppressed.

  Furthermore, according to the present embodiment, as the slider 4 moves toward the back side of the recess 5, at least a portion of the slider 4 that holds the bumper 2 is moved upward, and the bumper 2 is moved to the upper wall of the recess 5. Since it is made to abut against the front fender panel 1 forming the part, the gap between the front fender panel 1 and the bumper 2 can be narrowed, and the appearance can be improved.

  In particular, in the present embodiment, the arm 4a of the slider 4 is pushed up from the bottom by the arm 3b of the bracket 3, and the thickness of the arm 4a of the slider 4 is gradually increased from the back side of the recess 5 toward the opening side. Accordingly, the configuration in which the bumper 2 is pushed upward in accordance with the movement of the slider 4 toward the back of the concave portion 5 can be realized as a relatively simple configuration.

  Furthermore, according to the present embodiment, since the bracket 3 is provided with the locking mechanism that suppresses the slider 4 from coming out of the recess 5, it is possible to suppress the slider 4 and thus the bumper 2 from being separated from the recess 5. .

  In particular, in the present embodiment, the arm 3b of the bracket 3 and the claw portion 3d provided on the arm 3b function as a locking mechanism for the slider 4, and also function as a pressing mechanism that pushes up the arm 4a of the slider 4. Since it was set as the structure, compared with the case where these mechanisms are each provided separately, the structure can be simplified.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, the bracket and the slider are not limited to the configurations disclosed in the above embodiment, as long as they can exhibit the same operation and effect.

  Further, the mechanism for guiding the slider to be movable by the bracket is not limited to the above-described embodiment. For example, a protrusion may be provided on the bracket side and a groove may be provided on the slider side, and these may be fitted.

  Moreover, in the said embodiment, although the protrusion which functions as a stopper which controls the movement to the recessed part back side of a slider was provided in the bracket, you may provide this in the slider side.
