At this time, an operator pulls out the waist molding 2 sequentially from the rear end side, and finally pulls the front end of the waist molding 2 toward the upper rear side. As a result, the taper surface 36 of the engagement protrusion 31 of the end cap 10 on the front end side comes into contact with the edge of the engagement hole 38 of the flange 3 a, and the engagement protrusion 31 is on the edge of the engagement hole 38 with the taper surface 36. While sliding, the base portion is elastically bent and deformed. As a result, the engagement protrusion 31 and the engagement hole 38 are disengaged, and the waist molding 2 is completely removed from the flange 3a.

  As described above, in the mounting structure of the waist molding 2, the engagement protrusion 31 having the tapered surface 36 at the upper rear end is provided on the end cap 10 on the front end side, and the engagement protrusion 31 locks the flange 3a. Since the waist molding 2 is removed, the waist molding 2 is pulled upward and the taper surface 36 is slid on the edge of the locking hole 38 when the waist molding 2 is removed. The engagement between the cap 10 and the flange 3a can be easily released. Therefore, when this mounting structure is adopted, even if there is not enough space to insert a hand or a tool in the upper front end direction of the door outer panel 3, the end cap 10 is not damaged and the waist molding 2 is not damaged. The front end portion can be easily removed from the flange 3 a together with the end cap 10.

  In the case of this embodiment, since the engagement protrusion 31 of the end cap 10 is formed in a claw shape that can be bent and deformed with the root portion as a fulcrum, the engagement when the waist molding 2 is pulled to the upper rear side. There is an advantage that the protrusion 31 and the locking hole 38 can be easily released.

  Furthermore, in this embodiment, a displacement restricting surface 37 is provided on the top of the engagement protrusion 31 of the end cap 10, and a tapered surface 36 is provided adjacent to the rear end side of the waist molding 2 of the displacement restricting surface 37. Therefore, the upper displacement of the front end of the waist molding 2 is restricted without obstructing the sliding of the tapered surface 36 and the end edge of the locking hole 38 when the waist molding 2 is removed. The portion can be stably held at the set position on the flange 3a.

  In this embodiment, only the front end cap 10 engages the engagement protrusion 31 having the tapered surface 36 with the locking hole 38 on the flange 3a side, and the end cap 11 on the rear end Since the locking clip 14 is firmly fixed to the flange 3a, there is an advantage that the holding strength of the entire waist molding 2 in a state where the waist molding 2 is attached to the flange 3a can be increased.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
