Flexible structure and method for producing same

Abstract

A flexible structure with a multi-joint function is formed by connecting flexing parts in which wave washers are stacked and welded to each other. The flexible structure includes a first flexing part, a second flexing part, and a connection part. The first flexing part and the second flexing part are capable of flexing and extending. The connection part is welded in an axial direction between the first flexing part and the second flexing part and has a rigidity higher than the first flexing part and the second flexing part. The first flexing part and the second flexing part each include wave washers stacked in the axial direction and welded to each other. The connection part has a circulating shape in which an inner circumference and an outer circumference are each continuous in a circumferential direction.
