The present invention provides a flexible member having excellent load resistance and flexibility while achieving a reduction in size. This flexible member is provided with: a main body part which includes multiple wave washers that are stacked in an axial direction and are joined to one another by multiple joint parts, and which is capable of bending relative to the axial direction by elastic deformation of the wave washers; and easily deformable parts formed between the joint parts that are adjacent to one another in the circumferential direction in each wave washer.
