摘要：
A shock absorber (1A) includes a three-dimensional structure (S) composed of a unit structure (U) repeatedly, regularly and continuously arranged in at least one direction, the unit structure (U) being a three-dimensional shape formed by a wall (10) having an external shape defined by a pair of parallel planes or curved surfaces. When such unit structures (U) each occupy a hexahedral space representing a unit space and defined by mutually orthogonal three sides having a first side extending in a direction in which the shock absorber (1A) exhibits a shock absorbing function as the shock absorber (1A) receives a load and second and third sides each extending from one end of the first side in a direction orthogonal to the axial direction, and the first side has a length L1 and a longer one of the second and third sides has a length L2, the three-dimensional structure (S) includes as the unit structure (U) a unit structure satisfying 1.1 ≤ L1/L2 ≤ 4.0.
技术问题语段：
The patent text discusses various types of shock absorbers and how they can be used in shoes to absorb shock. A new type of shoe sole with a lattice structure is also described. The text also mentions the use of three-dimensional additive manufacturing to create objects with elastic materials that can be used for shoes. The technical problem addressed by the patent is how to improve shock absorption in shoes while maintaining their structure and design.
技术功效语段：
The present invention provides a shock absorber with a thickness added to a geometrical surface structure, which achieves large compressive stiffness easier than a shock absorber with a lattice or web structure. This results in a shoe sole that is lightweight and has an excellent shock absorbing function. The technical effects of this invention are improved performance and comfort for the shoes' wearer.
权利要求：
1. A shoe sole comprising a shock absorber comprising a three-dimensional structure (S) composed of a unit structure (U) repeatedly, regularly and continuously arranged in at least one direction, the unit structure (U) being a three-dimensional shape formed by a wall (10) having an external shape defined by a pair of parallel planes or curved surfaces, wherein the three-dimensional structure (S) is a triply periodic minimal surface with a thickness added thereto; when such unit structures (U) each occupy a hexahedral space representing a unit space and defined by mutually orthogonal three sides having a first side extending in an axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load and second and third sides each extending from one end of the first side in a direction orthogonal to the axial direction, and the first side has a length L1 and a longer one of the second and third sides has a length L2, the three-dimensional structure (S) including as the unit structure (U) a unit structure satisfying 1.1 ≤ L1/L2 ≤ 4.0, and wherein the shock absorber is disposed such that the axial direction is orthogonal to a tread (112a).
2. The shoe sole according to claim 1, wherein such unit spaces aligned in the axial direction each have an equal L1/L2.
3. The shoe sole according to claim 1 or 2, wherein the three-dimensional structure (S) includes, as the unit structure (U), unit structures each occupying a unit space having an external shape with a different dimension.
4. The shoe sole according to claim 3, wherein those unit structures (U) each occupying a unit space having an external shape with a different dimension are disposed in the axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load.
5. The shoe sole according to claim 3 or 4, wherein those unit structures (U) each occupying a unit space having an external shape with a different dimension are disposed in a direction intersecting with the axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load.
6. The shoe sole according to any one of claims 3 to 5, wherein a partition wall (50) that does not correspond to the wall (10) defining the unit structure (U) is provided between those unit structures (U) each occupying a unit space having an external shape with a different dimension.

8. The shoe sole according to claim 7, wherein the three-dimensional structure (S) has a meandering portion (11) which is a portion presenting a cross-sectional shape extending in a meandering manner when the three-dimensional structure (S) is cut along at least a specific plane, the meandering portion (11) has a reinforcement portion to reinforce a turning point (12) of the meandering portion (11), and the reinforcement portion is configured by an additional thickness portion (15, 15') provided at an internal corner portion of the turning point (12) to make the turning point (12) larger in thickness than another portion.
9. The shoe sole according to any one of claims 1 to 8, formed of either a resin material or a rubber material.
10. A shoe comprising: a shoe sole according to any preceding claim ; and an upper (120) provided above the shoe sole.
