  In the latter case, a plate-like flange portion having a substantially rectangular insertion port is integrally protruded upward on both side edges of the rear package trim, and a plate-like engagement is provided on the bottom rear surface of the pillar trim body. As a structure in which the stop projection is integrally provided through the seat so as to extend rearward of the vehicle body with a gap from the back surface of the pillar trim main body, the pillar trim is attached to the rear package trim and the rear pillar as follows.

  First, the lower end edge of the pillar trim is attached to the rear package trim by inserting and locking the locking projection into the insertion port of the flange portion from the inside of the vehicle. Next, the upper portion of the pillar trim is pressed toward the outside of the vehicle to approach the rear pillar, and the locking portion of the pillar trim is locked to the locked portion of the rear pillar.

  However, in such a mounting structure, the upper part of the pillar trim is in contact with the upper surface of the upper edge of the insertion opening of the flange portion with the locking projection inserted into the insertion opening and locked. When pressed outwardly, the lower edge of the insertion opening of the flange portion comes into pressure contact with the lower part on the base end side of the locking projection, and a vertical compression force acts on the base end side of the locking projection. At this time, the compressive force is transmitted to the vicinity of the base end of the seat portion, and the vicinity of the base end of the seat portion may be damaged, or the pillar trim surface near the base end of the seat portion may be whitened to deteriorate the appearance.

  The present invention has been made in view of such points, and the object of the present invention is to provide a white pillar trim in the vicinity of the seat portion where the locking projection is formed when the pillar trim is attached to the rear package trim and the rear pillar. In other words, the base portion of the seat portion and the locking projection is not damaged.

  In order to achieve the above object, the present invention is characterized in that the base end side of the locking projection of the pillar trim is compressed and deformed.

  Specifically, according to the present invention, in a state where the lower end edge of the resin pillar trim is attached to the resin rear package trim attached to the vehicle body, the engaging portion of the upper portion of the resin pillar trim is locked to the rear pillar. The following solution was taken for the structure of the pillar trim that is locked to the part and attaches the upper part to the rear pillar.

  That is, in the present invention, a plate-like flange portion having a substantially rectangular insertion port is integrally protruded upward at the vehicle width direction side edge extending in the vehicle longitudinal direction of the rear package trim, The pillar trim is provided with a pillar trim body integrally projecting on the back surface of the lower end toward the vehicle outer side and covering the rear pillar from the vehicle inner side, and the flange portion of the rear package trim is provided at a lower end of the seat portion. A plate-like locking projection that is inserted and locked into the insertion port from the inside of the vehicle and has a slit penetratingly formed on the base end side is integrally projected so as to extend rearward of the vehicle body with a gap from the back surface of the pillar trim body. The pillar trim locking projection is inserted and locked into the insertion port of the flange portion from the inside of the vehicle, and the top end of the seat portion is brought into contact with the upper surface of the upper edge of the insertion port from the inside of the vehicle. The lower end edge of the trim is attached to the rear package trim, and in this state, the upper side of the pillar trim is pressed toward the outside of the vehicle, thereby compressing and deforming the base end side of the locking projection so as to narrow the vertical width of the slit. In addition, the upper part of the pillar trim is brought close to the rear pillar, and the locking portion of the pillar trim is locked to the locked portion of the rear pillar.

  According to the present invention, when the lower end edge of the pillar trim body is attached to the rear package trim, the upper side of the pillar trim is pressed to the outside of the vehicle, and the lower edge of the insertion port of the flange portion is in pressure contact with the lower part on the base end side of the locking projection. The base end side of the locking projection is compressed in the vertical direction to narrow the vertical width of the slit, and the compressive force applied to the locking projection is absorbed by the compression deformation. Therefore, excessive compressive force is not transmitted to the vicinity of the base end of the seat portion, and it is possible to prevent damage to the seat portion and the vicinity of the base end of the locking projection, and to prevent the pillar trim surface near the base end of the seat portion from being whitened. Since it can prevent, the deterioration of the appearance of the said surface can be prevented.
