PROBLEM TO BE SOLVED: To provide a mating part structure of resin parts which can secure sufficient engaging strength even when having a mating part of two resin parts in a narrow area, prevent positional deviation and thereby improve appearance quality and simplify the structure of a molding die.SOLUTION: In a mating part structure of two back door trims 2 and 3 having mating parts 2a and 3a in narrow areas and assembled by mutual engagement, an engaging claw 21 and a first engagement hole 22 arranged at the base end of the engaging claw 21 are provided in the mating part 2a of the first back door trim 2, and a second engaging hole 31 arranged so as to correspond to the engaging claw 21 and a plug-in rib 32 arranged so as to correspond to the first engaging hole 22 are disposed on the same plane in the mating part 3a of the second back door trim 3. The engaging claw 21 is inserted into the second engaging hole 31, and the plug-in rib 32 is plugged into the first engaging hole 22 so that the mating parts 2a and 3a of the first and second back door trims 2 and 3 are engaged in a positionally regulated state. |
