The inner wall portion 15a extends in the vertical direction of the vehicle while being bent in the vehicle width direction, and an engaging portion is provided below the inner wall portion 15a.
The engaging portion is a locking portion 21 having an engaging claw 21a projecting outward from the inner wall portion 15a in the vehicle width direction and projecting upward toward the vehicle at the tip thereof, and the engaging portion 21 in the vehicle front-rear direction. It is provided with protruding portions 22 which are arranged on both sides and project outward from the inner wall portion 15a in the vehicle width direction.

The front door garnish inner 15B has an inner side inclined surface 15b that inclines inward in the vehicle width direction and toward the lower side of the vehicle from the lower end of the inner wall portion 15a and functions as an inner side joint portion, and an inner side inclined surface 15b from the lower end of the inner side inclined surface 15b to the lower side of the vehicle. It has an extending portion 15c extending toward.
Further, the front door garnish inner 15B is attached with an elastic member 19 that contacts the side sill outer 18A when the front door 13 is closed and seals between the front door garnish inner 15B and the side sill outer 18A.

The front door garnish outer 15A has an outer wall portion 15d as an outer surface extending in the vertical direction of the vehicle and in the front-rear direction of the vehicle, and a lower surface portion 15e that is bent at the lower end of the outer wall portion 15d and extends inward in the vehicle width direction to form a lower surface. It has an outer side inclined surface 15f that is inclined inward in the vehicle width direction and toward the lower side of the vehicle from the inner end portion of the lower surface portion 15e in the vehicle width direction, extends almost parallel to the inner side inclined surface 15b, and functions as an outer side joint portion. However, a bracket 20 is provided on the lower surface portion 15e.
The bracket 20 stands up from the lower surface portion 15e toward the upper side of the vehicle and extends in the vehicle front-rear direction, and extends from both ends of the vertical wall portion 20a in the vehicle front-rear direction toward the outside in the vehicle width direction, and the lower end thereof is the lower surface portion 15e. It is provided with a reinforcing portion 20b to be joined to. The vertical wall portion 20a is formed with an engaging hole 23 to which the locking portion 21 can be engaged and an insertion hole 24 into which each protruding portion 22 can be inserted. Each of the insertion holes 24 is formed to have a size substantially the same as the size of each protrusion 22, and in particular, the protrusion 22 is formed so as to be hardly movable in the vertical direction. The insertion hole 24 may be limited to at least restricting the movement of the protrusion 22 upward to the vehicle, and for example, a gap may be formed below the protrusion 22.

The front door garnish outer 15A is attached to the front door garnish inner 15B by engaging the engaging portion of the front door garnish inner 15B with the bracket 20 of the front door garnish outer 15A. The bracket 20 and the engaging portion described above are provided in a plurality of, for example, four locations in the front-rear direction of the vehicle 1.
In a state where the engaging portion and the bracket 20 are engaged, the outer side inclined surface 15f and the inner side inclined surface 15b are in contact with each other. In the present embodiment, a joining member 25 such as a double-sided tape or an adhesive is provided on the upper surface of the outer inclined surface 15f, and the outer inclined surface 15f and the inner inclined surface 15b are joined via the joining member 25. Has been done. At this time, the extending portion 15c extends below the lower end of the outer side inclined surface 15f. That is, the lower end 15C of the front door garnish 15 is composed of the extending portion 15c of the front door garnish inner 15B.

From the above configuration, in a vehicle in which the lower end 15C of the front door garnish 15 is located below the vehicle than the lower end 18C of the side sill 18, the lower end of the front door garnish inner 15B is closer to the vehicle than the lower end of the front door garnish outer 15A. Since it is located below, even if an obstacle such as a flap comes into contact with the lower end 15C of the front door garnish 15, the lower end 15C is located inside in the vehicle width direction and is usually difficult to see from the outside of the vehicle. Since it is configured, it is possible to prevent the design surface (front door garnish outer 15A) of the front door garnish 15 from being damaged.

Further, the front door garnish outer 15A is painted to improve the appearance, and the front door garnish inner 15B is not painted because it is difficult to see from the outside of the vehicle. The unpainted front door garnish inner 15B is located below the vehicle than the painted front door garnish outer 15A, so even if an obstacle touches the lower end 15C of the front door garnish 15. The paint on the front door garnish outer 15A does not come off, and deterioration of the appearance can be prevented.

Further, since the front door garnish inner 15B has an inner side inclined surface 15b and the lower end 15C of the front door garnish inner 15B is formed by the extending portion 15c extending downward from the lower end thereof, an obstacle comes into contact with the lower end 15C. Then, when there is an input from the lower side to the upper side of the front door garnish inner 15B, the input can be absorbed by the inner side inclined surface 15b and the input to the entire front door garnish 15 can be reduced. It is possible to suppress damage and deformation of the front door garnish 15.

Further, since the protruding portion 22 of the front door garnish inner 15B is inserted into the insertion hole 24 provided in the vertical wall portion 20a rising from the lower surface portion 15e of the front door garnish outer 15A, an obstacle comes into contact with the lower end 15C. When the front door garnish inner 15B is pushed up, the lower surface portion 15e moves upward together with the front door garnish inner 15B, so that it is possible to more reliably prevent the design surface of the front door garnish 15 from being scratched.

Further, since the outer side inclined surface 15f that extends parallel to the inner side inclined surface 15b and abuts on the inner side inclined surface 15b is provided on the front door garnish outer 15A, the outer side inclined surface 15f abuts on the inner side inclined surface 15b. Thereby, the positions of the front door garnish outer 15A inside in the vehicle width direction and above the vehicle can be restricted.
Further, when the front door garnish outer 15A is assembled to the front door garnish inner 15B in the vehicle width direction and the outer side inclined surface 15f and the inner side inclined surface 15b are joined as in the present embodiment. Because the inner side inclined surface 15b and the outer side inclined surface 15f are inclined, when the front door garnish outer 15A is assembled to the front door garnish inner 15B, the joining member 25 is a portion other than the inner side inclined surface 15b. It is possible to suppress sticking to the door and improve assembly workability.
The above-mentioned effect of the present invention is the same for the rear door garnish 16.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment described above, and is described in the scope of claims unless otherwise specified in the above description. Various modifications and changes are possible within the scope of the present invention.
For example, the inclination angle of the bent portion 15Ba with respect to the horizontal plane is preferably about 30 to 40 degrees, but is not limited to this angle.
The effects described in the embodiments of the present invention merely list the most preferable effects arising from the present invention, and the effects according to the present invention are not limited to those described in the embodiments of the present invention. ..
