Abstract:
1. A shock absorbing structure for a vehicle comprising at least one resin main body which includes a planar top wall to which a shock is to be applied and two planar leg walls which are formed integrally with said top wall such that said two leg walls respectively extend from opposite two end portions of said top wall so as to be opposed to each other, toward one of opposite sides of said top wall, which side is opposite to the other side thereof on which the shock is applied, said at least one resin main body being formed of a synthetic resin material, wherein said two leg walls are provided on said top wall so as to be inclined such that a distance between said two leg walls in a first direction in which said two leg walls are opposed to each other gradually increases with an increase in a distance in a second direction which is perpendicular to said first direction and which is away from said top wall toward distal portions of said two leg walls, with an obtuse interior angle being formed at each of corners which are formed by said top wall and the respective two leg walls, said top wall and said two leg walls being formed integrally with each other by using a synthetic resin material whose tensile elongation according to ASTM D638 is not less than 150%, an inner surface of said each of said corners being provided by a concave curved surface having a radius of curvature of not less than 2.0 mm, each of said leg walls having a longitudinal axis, and the axes of said walls extend parallel to one another, and wherein a deformation mode of each of said top walls and said respective two leg walls is a spreading of said leg walls apart from one another increasing both of said obtuse interior angles, each formed between one of said respective leg walls and said top wall.
