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. In the shock absorber (1A), a differently shaped portion (30) which does not correspond to the wall (10) defining the unit structure (U) is locally provided in a shock absorbing region which is a region in which the three-dimensional structure (S) has the unit structure (U) disposed.
技术问题语段：
The technical problem addressed in this patent is how to improve the shock absorbing function of shoes and other footwear while incorporating a shoe sole with a part having a lattice structure or other enhanced shock absorbing function. The patent describes various methods for manufacturing such shoes and objects using three-dimensional additive manufacturing methods.
技术功效语段：
The present invention provides a shoe sole with a shock absorber that has excellent shock absorbing function and durability. The shock absorber has a three-dimensional structure composed of a unit structure repeatedly, regularly and continuously arranged in at least one direction, and includes a reinforcement portion to reinforce a turning point of the meandering portion. The three-dimensional structure may have a Schwarz' P structure or a gyroid structure and may be formed of either a resin material or a rubber material. The shock absorber may be disposed such that an axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load is orthogonal to a tread.
权利要求：
1. A shoe sole comprising a shock absorber (1N, 1N1, 1N2, 1O), the shock absorber (1N, 1N1, 1N2, 1O) including 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 curved surfaces, the three-dimensional structure (S) being composed of a triply periodic minimal surface with a thickness added thereto, and having 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 shock absorber (1N, 1N1, 1N2, 1O) further including a reinforcement portion to reinforce a turning point (12) of the meandering portion (11).
2. The shoe sole according to claim 1, wherein the reinforcement portion is configured by an additional member (20) disposed to traverse an internal corner portion (13) of the turning point (12).
3. The shoe sole according to claim 1, wherein the reinforcement portion is configured by an additional thickness portion (15, 15') provided at an internal corner portion (13) of the turning point (12) to make the turning point (12) larger in thickness than another portion.
4. The shoe sole according to any one of claims 1 to 3, wherein the three-dimensional structure (S) has a Schwarz' P structure or a gyroid structure.
5. The shoe sole according to any one of claims 1 to 4, wherein the shock absorber (1N, 1N1, 1N2, 1O) is formed of either a resin material or a rubber material.
6. The shoe sole according to any one of claims 1 to 5, wherein the shock absorber (1N, 1N1, 1N2, 1O) is disposed such that an axial direction in which the shock absorber (1N, 1N1, 1N2, 1O) exhibits a shock absorbing function as the shock absorber (1N, 1N1, 1N2, 1O) receives a load is orthogonal to a tread (112a).
7. A shoe comprising: a shoe sole (110H) according to claim 1 to 6; and an upper (120) provided above the shoe sole.
