PROBLEM TO BE SOLVED: To restrain resonance of a pillar garnish by providing a plural number of reinforcing ribs along the cross sectional direction of a trimming material on a back surface of the synthetic resin made trimming material installed on the indoor side of a vehicle panel and providing a rib positioned between the auxiliary ribs on a side part back surface of a side window.
SOLUTION: It is constituted by connecting edge parts to each other so as to form closed cross section structure with an outer panel 11 and an inner panel 12 mutually on a cross section of a pillar 10 of a car body, and a thermoplastic resin pillar garnish 13 is installed on the side of the inner panel 12. A rib 15 is formed in parallel with reinforcing ribs 16 between the sector formed reinforcing ribs 16 on the side of a side window of the inner panel 12 on its back surface.
