Title:
衝撃吸収構造
Document Type and Number:
Japanese Patent JP5218662
Kind Code:
B2
Abstract:
There is provided a shock absorbing structure that can improve shock absorption performance by stabilizing the compressive deformation of a shock absorbing member in an axial direction. High-strength portions 31, 32, 33, and 34 controlling deformation and low-strength portions 36, 37, and 38 controlling deformation are alternately disposed. Accordingly, when a shock is applied to a front side member 2 from the front side of a vehicle, the front side member 2 can be deformed in the shape of a bellows. Further, the respective low-strength portions 36, 37, and 38, which are disposed closer to a rear end 2b side in a longitudinal direction, have higher strength. Therefore, the front side member 2 can be sequentially deformed from a front end 2a side.
