Cable protection and guide device

A cable protection and guide device, comprising:

• a multi-joint link formed by connecting a plurality of link members in a cable longitudinal direction, wherein the cable protection and guide device guides a cable from a cable fixed end to a cable movable end, the multi-joint link comprises a linear portion and a flexional portion, wherein the linear portion is in contact with a support surface of a support body and the flexional portion is separated from the support surface, the linear portion comprises an inner side and an outer side and the flexional portion comprises an inner side and an outer side, the inner side of the linear portion is connected to the inner side of the flexional portion, the outer side of the linear portion is connected to the outer side of the flexional portion, and at least part of the outer side is in contact with the support surface,
• wherein the multi-joint link comprises the plurality of link members and a pair of holding members, in which the pair of holding members is attached to at least one part of the plurality of link members and comprises a flexional inner side holding member and a flexional outer side holding member to hold the cable between a flexional inner side and a flexional outer side,
• wherein the at least one part of the plurality of link members comprises a connection pin arranged at one end side thereof in the cable longitudinal direction, a pin hole arranged at the other end side thereof in the cable longitudinal direction to be rotatably engaged with the connection pin of another link member, and a flexional inner side engaging part and a flexional outer side engaging part disposed between the connection pin and the pin hole in the cable longitudinal direction,
• wherein the flexional inner side holding member comprises an inner side base part to be engaged with the flexional inner side engaging part and an inner side holding part, which extends from the inner side base part toward a width direction of the multi-joint link and is in contact with the cable at the flexional inner side, wherein the inner side base part and the inner side holding part are formed integrally with each other, the width direction of the multi-joint link is perpendicular to the cable longitudinal direction, and
• wherein the flexional outer side holding member comprises an outer side base part to be engaged with the flexional outer side engaging part and an outer side holding part, which extends from the outer side base part toward the width direction of the multi-joint link and is in contact with the cable at the flexional outer side and cooperates with the inner side holding part of the flexional inner side holding member to hold the cable, wherein the outer side base part and the outer side holding part are formed integrally with each other.
