To improve assembling workability in the case of connecting an ornament member to a door trim body in an abutting manner, and increase a design freedom of configuration design or the like.

The ornament member 14 has a step 32 and a latch protrusion 34 continuing from the step 32. The door trim body 12 has a latch hole 44 through which the latch protrusion 34 is inserted while being elastically deformed and to which a retaining salient 46 latches by the elastic return of the latch protrusion 34. Consequently, The ornament member 14 can be connected to the door trim body only by making the ornament member approach the door trim body in an abutting direction as indicated by an outline arrow and inserting the latch protrusion into the latch hole 44. In the case that upright sections 22 and sidewall sections 30 are provided on both ends in the anteroposterior direction of a vehicle, and in the vertical direction of the vehicle, both the ends can be integrally connected by anchoring the latch protrusion 34 to the latch hole 44, and assembling work can easily and immediately be performed without worsening positioning capability so as to increase the freedom of the design such as configuration design or the like.
