摘要： PROBLEM TO BE SOLVED: To prevent pillar garnishes from scattering away when bags are inflated. SOLUTION: Between a pillar inner panel 34 and a pillar garnish 40 in a front pillar 20, a front bag portion 16D is stored in folds. That area of the front bag portion 16D which corresponds to a bag storage portion 42B of the pillar garnish 40 is a non-inflatable area 16D1. An inflation of the front bag portion 16D offers an accordingly reduced pressure load F1 acting on the bag storage portion 42B to thus prevent the pillar garnish 40 from scattering away.

摘要： PROBLEM TO BE SOLVED: To improve the fatigue strength of the casting without generating new casting defects, on the surface of the casting, by moving a tool of the material harder than that while being rotated in a state of being slidably contacted with it and plastically flowing the material of the casting in the slidably contacted part by the generated frictional heat and pressure. SOLUTION: Simultaneously with frictional stirring joint, by frictional heat, the temp. of the material is increase to the one below the m.p. to reduce the flowing stress of the material, and by the pressure of the rotating movement in a slidable contact, the material is plastically flowed. In this way, the material is stirred and mixed at a high temp. under the m.p., and the material at the rear part of the moving tool loses the frictional heat and is rapidly cooled. Namely, the casting is subjected to locally strong hot working at the slidably contacted part with the tool, by which gappy defects such as blowholes, pinholes and shrinkage cavities are stuck and pressure and solved, and moreover, it is rapidly cooled after the hot working, the hot-worked structure is frozened as it is and is brought to a room temp., by which an extremely fine structure can be obtd.
