CELL INSTALLATION STRUCTURE FOR VEHICLE

A battery mounting structure for a vehicle (10) includes a battery frame upper (22) fabricated of fiber-reinforced resin, a battery frame lower (24) fabricated of fiber-reinforced resin, and an intermediate member (30) fabricated of fiber-reinforced resin. A battery (16) that is disposed at a vehicle body lower side of a floor panel (12) is attached at the battery frame upper (22). With the battery frame upper (22), the battery frame lower (24) structures a closed cross section structure. The intermediate member (30) is interposed between the battery frame upper and the battery frame lower. The intermediate member (30) is provided with a plural number of upper end portions (32B) that abut against or are disposed close to a lower face (22A) of the battery frame upper (22) and a plural number of lower end portions (32C) that abut against or are disposed close to an upper face (24A) of the battery frame lower (24). Thus, the strength of a battery frame (20) formed of a fiber-reinforced resin material with respect to loads inputted from the vehicle body lower side is improved.
