トルクリミツター。 A rotating body on the driving side and a rotating body on the driven side are provided on the same axis with their flanges facing each other, and a recess is formed in one of the flange portions to pass through the flange portion, and a recess is formed in the other flange portion. A concave groove is formed to match the concave portion, and a roller is housed in the concave portion, and the outer circumferential portion on one side of the roller is engaged with the concave groove, and the outer circumferential portion on the other side is engaged with the concave groove. An annular overload detection panel that presses the roller toward the concave groove is brought into contact with the overload detection panel, and a torque spring that biases the overload detection panel toward the roller along the axial direction is brought into contact with the overload detection panel. In the torque limiter, an elastic force cutoff is provided between the overload detection panel and the torque spring to block the elastic force of the torque spring from being transmitted to the overload detection panel when the overload detection panel is pushed back. The elastic force interrupting means includes a steel ball interposed between the inner circumferential surface of the overload detection panel and the outer circumferential surface of the boss portion of one of the rotating bodies, and the steel ball and the torque spring. a thrust ring interposed between and in contact with the boss portion, and an inclined surface formed on the outer circumferential surface of the boss portion to guide the steel ball radially outward to be compressed along the axial direction; Formed on the inner circumferential surface of the overload detection panel, it locks the steel balls guided outward in the radial direction, and when the overload detection panel is pushed back along the axial direction, the steel balls are guided in the radial direction. and an engagement recess that pushes back inward to release the engagement with the steel ball.
