Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A flexible member comprising: a main body part that has a plurality of 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 of the main body part and being linked to another member, wherein a deformation amount of the linking member is smaller than a deformation amount of the wave washer, when the main body part is bent, wherein the linking member is an annular plate member having the deformation amount smaller than the deformation amount of the wave washer of the main body part, wherein the plurality of wave washers individually includes a plurality of mountain parts and valley parts individually provided between the mountain parts in a circumferential direction, and adjacent wave washers abut each other, wherein the linking member comprises a plurality of flat washers stacked in the axial direction and directly joined to each other. 2. The flexible member according to claim 1 , wherein the plurality of wave washers are joined in a state in which the mountain parts and the valley parts of adjacent wave washers abut each other, and wherein the plurality of flat washers is joined to each other at positions corresponding to joint portions of the wave washers. 3. The flexible member according to claim 1 , wherein the linking member comprises: a plurality of flat washers stacked in the axial direction and joined to each other. 4. The flexible member according to claim 3 , wherein the plurality of wave washers are joined in a state in which the mountain parts and the valley parts of adjacent wave washers abut each other, and wherein the plurality of flat washers is joined to each other at positions corresponding to joint portions of the wave washers.
