Abstract
The present invention comprises: a first bending part and a second bending part which are capable of bending elastically; a connection part which connects the first bending part and the second bending part, and which has higher bending rigidity than the first bending part and the second bending part; and a plurality of first cord-like members which are attached to the first bending part, which are inserted through the first bending part, the connection part, and the second bending part, and which are capable of bending the first bending part via tension on the second bending part side. The first cord-like members each have a plurality of divided parts which are divided in the connection part and dispersed in the circumferential direction, and which are inserted through the second bending part in this dispersed state.
