Impact absorbing structure of vehicles

An impact absorbing structure of a vehicle,

• the impact absorbing structure comprising an impact absorbing member made of fiber-reinforced resin, the impact absorbing member including a pair of left and right side wall portions and a coupling portion coupling the pair of side wall portions, the pair of left and right side wall portions being arranged at a vehicle body forward/rearward direction tip end-side part of the vehicle and each containing a plurality of reinforced fibers arranged so as to continuously extend in a vehicle body forward/rearward direction, wherein:
• each of the pair of side wall portions includes
• a plurality of concave and convex portions that are concave and convex in a vertical sectional view perpendicular to the forward/rearward direction and extend in a horizontal direction,
• a plurality of intermediate curved portions forming at least a part of the concave and convex portions, a bumper reinforcement being attached to tip end portions of the plurality of intermediate curved portions, and
• an upper curved portion continuous with an upper side of the plurality of intermediate curved portions, the upper curved portion having a substantially partial conical shape and a substantially partial circular-arc vertical section perpendicular to the forward/rearward direction;
• each of the plurality of concave and convex portions is formed such that a depth thereof in a vehicle width direction decreases toward a tip end portion of the vehicle;
• and
• the upper curved portion is formed such that a diameter thereof increases toward a base end of the upper curved portion.
