The space between the door frame 16 and the division bar 20 is sealed.

  Here, in the vehicle seal structure 10, the engagement protrusion 48 provided on the bent portion 40 </ b> C of the rear glass run 40 is engaged with the engagement receiving portion 50, so that the bent portion 40 </ b> C becomes the front groove of the division bar 20. It is possible to prevent the dropout from 38 and displacement. That is, since it is formed by mold forming using a split mold, a fixed lip portion 46 (undercut structure with respect to the split mold) similar to the rear edge portion 40A cannot be formed. Using the mating projection 48, the division bar 20 is prevented from falling off and being displaced from the front groove 38.

  For example, in comparison with the comparative example 100 shown in FIG. 9A and FIG. 9B, in the comparative example 100, the engagement receiving portion 50 is not provided, and the engagement protrusion 48 is engaged. The surface 48 </ b> A is configured to prevent the bent portion 40 </ b> C from dropping from the front groove 38 of the division bar 20 by engaging with the overhanging portion 38 </ b> B of the division bar 20. In the comparative example 100, since the overhanging portion 38B is a folded portion of a metal plate having a round shape (tapered shape), a sufficient holding effect cannot be obtained.

  On the other hand, in the vehicle seal structure 10 according to the embodiment of the present invention, the engagement receiving portion 50 having the engagement receiving surface 50A formed substantially corresponding to the engagement surface 48A of the engagement protrusion 48 is provided. Therefore, it is possible to reliably prevent the bent portion 40C from falling off and being displaced from the front groove 38. Therefore, the bent portion 40C of the rear glass run 40 is firmly fitted and held on the upper portion of the division bar 20, and the floating from the division bar 20 is prevented or suppressed.

  Thereby, in the automobile to which the vehicular seal structure 10 is applied, the appearance from the outside of the vehicle body around the rear door 12 is improved, the sealing performance by the rear glass run 40 is improved, and wind noise is suppressed. Further, when the rear glass run 40 is mounted after the protector 28 is mounted on the outer wall 20 </ b> B, a feeling of moderation can be obtained as the engagement protrusion 48 gets over the engagement receiver 50.

  Further, at the time of mounting, the reinforcing piece 52 is engaged with the connecting wall 20 </ b> C and the excessive deformation of the engagement receiving portion 50 is prevented, so that the engagement protrusion 48 is reliably engaged with the engagement receiving portion 50. Since the engagement receiving portion 50 is reinforced by the reinforcing piece 52 in the direction in which the rear glass run 40 is dropped (extracted) from the division bar 20, a sufficient holding effect can be obtained by the resin-made engagement receiving portion 50. it can.

  Thus, in the vehicle seal structure 10 according to the embodiment of the present invention, the rear glass run 40 can be effectively held against the division bar 20.

  In addition, since the engagement receiving portion 50 is provided integrally with the protector 28, the above-described effects can be obtained without increasing the number of parts compared to the comparative example 100.

  In the above embodiment, a holding structure is provided by engaging the engagement protrusion 48 and the engagement receiving portion 50 on the outer side of the vehicle body of the rear glass run 40 (the portion of the outer wall 20B positioned above the upper end of the inner wall 20A). However, the present invention is not limited to this, and in the configuration in which the inner wall 20A overlaps the bent portion 40C of the rear glass run 40 in the vertical direction, the engagement protrusion 48 on the outside of the vehicle body, the engagement receiving portion Instead of or together with 50, an engagement protrusion 48 and an engagement receiving portion 50 may be provided inside the rear glass run 40 in the vehicle body.
