Disclosed is a pivot-arm type manipulator device, comprising an arm member that pivots about an axis by being manipulated, and a friction contact unit that generates friction force as the arm member pivots. At least one of the following differs between a first region of a small degree of manipulation vis-à-vis the arm member and a second region of the degree of manipulation vis-à-vis the arm member that is greater than the degree of manipulation of the first region: the friction coefficient between two members that configure the friction contact unit, the pressing load that acts between the two members that configure the friction contact unit, or the distance in the radial direction between the axis and the friction contact unit. The resistance torque that is applied to the arm member about the axis by friction force accordingly varies with the degree of manipulation vis-à-vis the arm member. |
