The clutch includes a sun gear, an internal gear, planetary gears, and a carrier. The sun gear is configured to switch between a fixed state and a non-fixed state. The internal gear is coupled to the input shaft in a torque transmittable manner. The planetary gears are configured to mesh with the sun gear and the internal gear. The carrier is coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably. The carrier includes a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch. ## Claims ### Claim 1 A clutch configured to mechanically establish and disestablish a torque transmission path between an input shaft through which a torque is input and an output shaft through which the torque is output, the clutch comprising: a sun gear configured to switch between a fixed state and a non-fixed state; an internal gear coupled to the input shaft in a torque transmittable manner; planetary gears configured to mesh with the sun gear and the internal gear; and a carrier coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably, the carrier comprising a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch. ### Claim 2 (depends on 1) The clutch according to claim 1, wherein the coupling portion comprises a tapped hole in which the detachment member is screwed. ### Claim 3 (depends on 1) The clutch according to claim 1, wherein the coupling portion comprises a through hole in which the detachment member is inserted, the through hole being formed in such a manner that when the inserted detachment member is rotated, the detachment member is caught in the through hole. ### Claim 4 (depends on 1) The clutch according to claim 1, wherein the coupling portion comprises a loop in which the detachment member is hooked. ### Claim 5 (depends on 1) The clutch according to claim 1, wherein the carrier comprises two plates configured to hold and rotatably support the planetary gears between the two plates, and supports held between the two plates to support the two plates while keeping the two plates at a distance from each other, and wherein the coupling portion is disposed at a position on one of the two plates where the two plates hold none of the planetary gears and the supports. ### Claim 6 (depends on 1) The clutch according to claim 1, wherein the output shaft is spline-fitted to the carrier. ### Claim 7 A steering device comprising a clutch configured to mechanically establish and disestablish a torque transmission path between an input shaft through which a torque is input and an output shaft through which the torque is output, the clutch comprising: a sun gear configured to switch between a fixed state and a non-fixed state; an internal gear coupled to the input shaft in a torque transmittable manner; planetary gears configured to mesh with the sun gear and the internal gear; and a carrier coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably, the carrier comprising a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch. ### Claim 8 A method for disassembling a clutch configured to mechanically establish and disestablish a torque transmission path between an input shaft through which a torque is input and an output shaft through which the torque is output, the clutch comprising: a sun gear configured to switch between a fixed state and a non-fixed state; an internal gear coupled to the input shaft in a torque transmittable manner; planetary gears configured to mesh with the sun gear and the internal gear; and a carrier coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably, the carrier comprising a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch, the method comprising coupling the detachment member to the coupling portion to detach the carrier from the clutch. ### Claim 9 (depends on 2) The clutch according to claim 2, wherein the carrier comprises two plates configured to hold and rotatably support the planetary gears between the two plates, and supports held between the two plates to support the two plates while keeping the two plates at a distance from each other, and wherein the coupling portion is disposed at a position on one of the two plates where the two plates hold none of the planetary gears and the supports. ### Claim 10 (depends on 3) The clutch according to claim 3, wherein the carrier comprises two plates configured to hold and rotatably support the planetary gears between the two plates, and supports held between the two plates to support the two plates while keeping the two plates at a distance from each other, and wherein the coupling portion is disposed at a position on one of the two plates where the two plates hold none of the planetary gears and the supports. ### Claim 11 (depends on 4) The clutch according to claim 4, wherein the carrier comprises two plates configured to hold and rotatably support the planetary gears between the two plates, and supports held between the two plates to support the two plates while keeping the two plates at a distance from each other, and wherein the coupling portion is disposed at a position on one of the two plates where the two plates hold none of the planetary gears and the supports. ### Claim 12 (depends on 2) The clutch according to claim 2, wherein the output shaft is spline-fitted to the carrier. ### Claim 13 (depends on 3) The clutch according to claim 3, wherein the output shaft is spline-fitted to the carrier. ### Claim 14 (depends on 4) The clutch according to claim 4, wherein the output shaft is spline-fitted to the carrier. ### Claim 15 (depends on 5) The clutch according to claim 5, wherein the output shaft is spline-fitted to the carrier. ### Claim 16 (depends on 9) The clutch according to claim 9, wherein the output shaft is spline-fitted to the carrier. ### Claim 17 (depends on 10) The clutch according to claim 10, wherein the output shaft is spline-fitted to the carrier. ### Claim 18 (depends on 11) The clutch according to claim 11, wherein the output shaft is spline-fitted to the carrier.
