Abstract: A reinforcing structure is provided to improve reinforcing effect for a body frame of a vehicle. A front pillar 10 as the body frame includes an outer member and a reinforcement 13. The reinforcing structure has a waveform adjusting mechanism 100 in addition to the outer member 11, 12 and the reinforcement 13. The waveform adjusting mechanism 100 adjusts various properties of peaks of respective waveforms in the buckling mode of the outer member 11, 12 and the reinforcement 13. The reinforcement 13 is connected to the outer member 11, 12 at its part except a minimum strength part of the outer member 11, 12. The waveform adjusting mechanism 100 is formed by the minimum strength part and a relief space S between the vicinity of the minimum strength part of the outer member and the reinforcement 13. Owing to the provision of the relief space S, it is possible to prevent a deformation of the outer member 11, 12 from transmitting to the reinforcement 13 immediately.

Abstract: A reinforcing structure is provided to attain sufficient reinforcing effect for a body frame without increasing a weight of a vehicle. The reinforcing structure includes a front pillar (3) whose peripheral wall has an outer panel (13) and a reinforcement (14) to provide a double wall structure, and an adjusting mechanism (15) for making a buckling-mode waveform of the outer panel (13) in a substantially-reversed phase to a buckling-mode waveform of the reinforcement (14). The adjusting mechanism (15) includes a plurality of beads (16) formed on a top wall of the reinforcement (14). Owing to the deformation of the outer panel (13) in a substantially-reversed phase to the deformation of the reinforcement (14), a resistance force due to contact between the outer panel (13) and the reinforcement (14) allows a deformation of the front pillar (3) to be is restricted to enhance reinforcing effect of the reinforcing structure.
