The manipulator 1 includes a main unit 2, a elongated member 3 that extends from the main unit 2, a bending assembly 4 connected to the elongated member 3, a coupling member 5 for transmission of power for putting the bending assembly 4 into operation, a drive unit 21 for generating power for the coupling member 5, and a regulator 6 that is interposed between the bending assembly 4 and the drive unit 21 and urges the coupling member 5 in a direction of intersecting a path taken by the coupling member 5.
