  • Patent number: 10492669
    Abstract: The present invention provides a bending device which is capable of easily controlling a bending motion with superior controllability. A portion of an elastic tube body (11) opposite a portion in which a non-stretching body (4) is fixed inflates in a circumferential direction of the elastic tube body (11) in response to increase in an internal pressure of the elastic tube body (11), and an elastic tube (1P) bends in a step-wise angle corresponding to the number of layers of a multi-layer structure. The portion of the elastic tube body (11) in which the non-stretching body (4) is fixed is thicker than the remaining portion of the elastic tube body (11).
