Abstract: A flexible member is provided which can have excellent load resistance and flexibility while being more compact. This flexible member has a main body 19 which comprises multiple annular wave washers 23 laminated in the axial direction and bonded together by multiple bonding units 21, and which is bendable in the axial direction through elastic deformation of the wave washers 23. The bonding units 21 comprise a pair of linear welded parts 25a, 25b which, from the inner surface 23e towards the outer surface 23f of the wave washers 23, gradually become further apart from each other in the circumferential direction.
