Patent abstract
A spider with an enhanced structure is disclosed. The spider has a plurality of concentric corrugations each of which has a plurality of inflections so that the concentric corrugations have polygonal shapes. With this enhanced structure, a spider can have an improved strength while maintaining an appropriate flexibility. A spider with the enhanced structure can avoid deformations due to un-uniform applications of external forces over a long period of time.
