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.

Abstract: A seat operating device comprising: an operation member; a first clutch member that is connected to an adjusting mechanism, and in which is formed a first cut-out portion that opens outwardly in a rotation radial direction of the first clutch member; a second clutch member that is connected to another adjusting mechanism, and in which is formed a second cut-out portion that opens outwardly in a rotation radial direction of the second clutch member; and a switching member having a first engaging portion and a second engaging portion that are positioned at mutually opposite sides across a rotational center. When the switching member is positioned at one end of a range of movement of the switching member, the first engaging portion engages with the first cut-out portion, and, when the switching member is positioned at another end of the range of movement, the second engaging portion engages with the second cut-out portion.

Abstract: A bending operation mechanism comprises: an elastically bendable driving part; an elastically bendable driven part that is provided separate from the driving part; and a linking part that connects the driving part and the driven part, and tensions and bends the driven part in accordance with bending of the driving part. The driving part and the driven part each comprise an inner coil part and an outer coil part that are bendable with respect to the axial direction, and wound parts corresponding to the inner coil part are respectively fitted to pitches between adjacent wound parts of the outer coil part.
