Abstract: Provided is a flexible member that can exhibit excellent load resistance and flexibility while achieving a reduction in size. This flexible member includes: a main body part which has multiple wave washers stacked in an axial direction and joined to each other, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers; and a linking member that is elastically deformable, the linking member being provided at an end part of the main body part and being linked to other member. A deformation amount of the linking member is smaller than a deformation amount of the wave washer, when the main body part is bent.
