Abstract
Provided are a bending structure and a flexible tube for a medical manipulator, which comprise a main body that is composed of the wave washers stacked in an axial direction and kept a stacked state, the main body being bendable according to the expansion and contraction in the axial direction. Accordingly, linearity of load characteristics based on load and a bending angle is made high to make it possible to obtain the flexible tube having superior load bearing and bendability while conducting size reduction.
