A side sill garnish at the outside of a side sill of a vehicle has a garnish main body as an outer surface of the side sill garnish; and a sound absorbing member provided on the inside of the garnish main body, and has a rigid member at an outer periphery of the sound absorbing member. The rigid member is attached to the garnish main body. Preferably, the sound absorbing member is made of a foam material, and the rigid member is formed by compressing the foam material. For example, the sound absorbing member, made of a foam material, has portions for fastening the sound absorbing member to the main body using clips; and these portions are formed by compressing the foam material. In another example, the sound absorbing member has rigid members on opposite sides in the outer periphery, and the rigid members are attached to the main body.

A floor structure of a vehicle body capable of enhancing rigidity against a external force from a side of the vehicle body includes a pair of right and left side sills, a pair of front and rear cross members provided between the pair of right and left side sills, and a floor panel surrounded by the pair of right and left side sills and the pair of front and rear cross members. The floor panel is provided thereover with beads in a concentric arc shape spreading from parts at which the side sills and the cross members are vertically joined to each other. Reinforcement members are provided at corners defined by the side sills and the cross members in such a manner that the reinforcement members are slantingly placed and joined to the side sills and cross members.
