When an external force from above is applied to the cap cover 39 that covers the opening 53 of the main body 38, the cap cover 39 is detached from the opening 53. Therefore, each of the cover main body 31, the vertical wall 33, and the hood seal surface 35 In this position, the rigidity of the cowl top cover 16 when the external force is applied is reduced and easily deformed, the peak of the reaction force against the external force is reduced, and the impact can be more reliably mitigated.

  That is, since the cap cover 39 constructs a part of multiple faces extending from the cover main body portion 31, the vertical wall portion 33, and the hood seal surface portion 35, the cowl top cover 16 at the time of external force action by the separation of the cap cover 39 from the opening 53. Can be easily reduced in rigidity.

  In particular, the vertical wall portion 33 and the hood seal surface portion 35 which act as ribs for maintaining the strength, which are continuous in the longitudinal direction of the cowl top cover 16, are divided by the separation of the cap cover 39 from the opening portion 53, and external force The rigidity of the cowl top cover 16 during operation can be more easily and reliably reduced.

  As a result, the cowl top cover 16 is provided with positions where the reaction force against the external force is likely to be relatively high, such as the vicinity of the longitudinal end of the cowl top cover body 38 (the cowl top cover 16) and the vicinity of the wiper pivot hole 46. However, the peak of the reaction force can be surely reduced, and the pedestrian protection performance can be further improved.

  In this way, it is possible to realize an impact absorbing structure having characteristics suitable for the cowl top cover 16 that covers the cowl portion 15 between the hood 12 and the windshield 14 of the vehicle body 10.

  In addition, since an opening for work such as retightening the bolt 64 can be used as the opening 53, the configuration can be made common, and the manufacturing can be performed more easily and inexpensively.

  Furthermore, the main surface portion 83 and a locking portion 84 projecting from the lower portion of the main surface portion 83 are formed in a substantially U-shaped cross section at a position facing the opening 53 (opening body 61) of the cap cover 39. Set the locking claw 81 and insert it between the main surface portion 83 of the locking claw 81 and the locking portion 84 at the edge of the opening 53 (opening main body 61) of the cowl top cover main body 38. By projecting the locking receiving portion 66 that receives the locking claw portion 81, the terminal portion (rear end portion) and the opening portion of the cowl top cover body 38 that are at positions facing the opening portion 53 of the cap cover 39 are provided. The edge portions of 53 have flange-like cross sections, respectively, and the surface rigidity of the cap cover 39 and the cowl top cover main body 38 is improved. As a result, the molding deformation of the cap cover 39 and the cowl top cover main body 38 can be suppressed. Therefore, it is possible to improve the alignment quality of the cowl top cover body 38 and the cap cover 39 with the cap cover 39 attached to the opening 53. Specifically, a step is unlikely to occur between the edge of the opening 53, which is a dividing line between the cowl top cover body 38 and the cap cover 39, and a terminal portion of the cap cover 39, and the meandering of the dividing line is unlikely to occur. .

  The cowl top cover 16 is fixed to the vehicle body panel 22 at the lower front side, that is, the mounting structure, the mounting structure such as the fitting structure to the edge 14a of the windshield 14, or the mounting structure of the hood seal 51 or the hood seal 51. The structure itself can take various configurations.

  For example, the hood seal surface portion 35 at the upper end portion of the vertical wall portion 33 may be formed in a shape extending from the upper end portion of the upper vertical wall portion 41 to the vehicle rear side instead of the vehicle front side.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the second embodiment, the cover main body portion 31 of the first embodiment has a protruding portion 99 protruding in a mountain shape upward along the rear edge portion of the hood 12 at the position of the cowl portion 15. The hood seal surface portion 35 projecting rearward from the upper end portion of the vertical wall portion 33 and the projecting portion 99 of the cover main body portion 31 are continuous in the front-rear direction. That is, in the present embodiment, the cowl top cover 16 does not include the connecting portion 32, and the vertical wall portion 33 is not branched vertically.

  The projecting portion 99 prevents, for example, snow from entering the engine room 11, and is continuous over both sides of the cowl top cover 16, which is the longitudinal direction.

  The opening 53 is opened across the cover main body 31, the protrusion 99, the hood seal surface 35, and the vertical wall 33.

  Accordingly, the cap cover 39 includes a sub-cover main body portion 77 that forms part of the cover main body portion 31, a sub-projection portion 100 that forms part of the protrusion 99, a sub-hood seal surface portion 79 that forms part of the hood seal surface portion 35, and A sub-vertical wall 78 forming a part of the vertical wall 33 is continuously formed.

  Also in the present embodiment, in the normal state shown in FIG. 5A with the hood 12 closed, a pedestrian moves from the upper front side to the hood 12 as shown by a broken line A and an arrow B in FIG. When a strong external force exceeding a predetermined value is received, such as when it collides, the hood 12 is deformed downward, and the hood seal surface portion 35 of the cowl top cover 16 that contacts the hood 12 via the hood seal 51 is lowered. Push down toward. With this load, the cap cover 39 having the sub hood seal surface portion 79 constituting a part of the hood seal surface portion 35 has the folded portion 96 with respect to the lower support portion 74 from the state shown by the two-dot chain line to the state shown by the solid line. Then, it shifts to the lower front side and detaches (drops) downward from the opening 53 of the cowl top cover main body 38. As a result, the cover main body portion 31, the vertical wall portion 33, and the projecting portion 99 of the cowl top cover 16 are partially opened by the opening portion 53 to form a substantially B-shaped weak structure, and the vertical wall portion 33, the hood seal The surface portion 35 and the projecting portion 99 are divided by the opening 53, the rigidity of the cowl top cover 16 is lowered at the position of the opening 53, and the cowl top cover main body 38 remaining on the vehicle body 10 side is easily deformed and shocked. The effects similar to those of the first embodiment, such as absorption, can be obtained.

  In each of the above-described embodiments, the cover mounting portion 34 is not limited to a structure that sandwiches the vicinity of the edge portion 14a of the windshield 14 from above and below, and is placed on the upper surface of the windshield 14 as a flat plate, for example. It can also be set as the structure contact | abutted.

  Further, in the above-described embodiment, the configuration of the vertical wall portion 33 is formed over the entire length or substantially the entire length of the cowl top cover 16, but is not limited to this configuration, and only a part of the cowl top cover 16 in the longitudinal direction is formed. It can also be provided. In this case, the same effect can be obtained by forming the opening 53 at a position corresponding to the vertical wall 33 and covering the opening 53 with the cap cover 39.

  Furthermore, the opening 53 can be set at any place where it is desired to reduce the reaction force against the external force as long as it opens over at least the cover main body 31, the vertical wall 33, and the hood seal surface 35.

  The cowl top cover main body 38 of the cowl top cover 16 can be divided into, for example, the vehicle width direction and the like, and can be combined by a connecting structure. Further, the cowl top cover 16 can be provided in a portion other than the front portion of the vehicle body 10, and can be disposed, for example, between the rear glass and the rear trunk hood.

  The present invention can be applied to, for example, a cowl top cover disposed between a windshield of a vehicle and a hood.
