A clutch apparatus comprising: at least one clutch drum; a clutch case disposed around a perimeter of the clutch drum, wherein the clutch apparatus is capable of selectively switching between restriction and allowance of relative rotation between the clutch drum and the clutch case in one direction; an endless guide groove circumferentially provided on one of an outer surface of the clutch drum and an inner surface of the clutch case; slide grooves (32a, 32b) axially provided on the other of the outer circumferential surface of the clutch drum or the inner surface of the clutch case; and a plurality of moving objects (40a, 40b) disposed between the guide groove and the slide grooves (32a, 32b) and being capable of relatively moving along the guide groove with the relative rotation between the clutch drum and the clutch case, wherein the guide groove includes: at least one stop part capable of stopping the moving objects (40a, 40b), wherein when the moving objects (40a, 40b) are stopped by the stop part, relative rotation between the clutch drum and the clutch case in the one direction is restricted; a one-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the one direction; characterized in, that the guide groove further includes: an other-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the other direction; and at least one return groove that guides the moving objects (40a, 40b) from the one-direction orbiting groove to the other-direction orbiting groove when the clutch drum and the clutch case are relatively rotated in the other direction with the moving objects (40a, 40b) located in the one-direction orbiting groove; and the clutch apparatus is configured such that at least two of the moving objects (40a, 40b) are stopped by the stop part at different timings, and the clutch apparatus has at least one of configurations 1) and 2), wherein in configuration 1) the moving objects (40a, 40b) are disposed on a single guide groove, and in configuration 2) the guide groove includes a plurality of guide grooves (21A, 21B) and each guide groove includes at least one moving object (40A, 40B). at least one clutch drum; a clutch case disposed around a perimeter of the clutch drum, wherein the clutch apparatus is capable of selectively switching between restriction and allowance of relative rotation between the clutch drum and the clutch case in one direction; an endless guide groove circumferentially provided on one of an outer surface of the clutch drum and an inner surface of the clutch case; slide grooves (32a, 32b) axially provided on the other of the outer circumferential surface of the clutch drum or the inner surface of the clutch case; and a plurality of moving objects (40a, 40b) disposed between the guide groove and the slide grooves (32a, 32b) and being capable of relatively moving along the guide groove with the relative rotation between the clutch drum and the clutch case, wherein the guide groove includes: at least one stop part capable of stopping the moving objects (40a, 40b), wherein when the moving objects (40a, 40b) are stopped by the stop part, relative rotation between the clutch drum and the clutch case in the one direction is restricted; a one-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the one direction; characterized in, that the guide groove further includes: an other-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the other direction; and at least one return groove that guides the moving objects (40a, 40b) from the one-direction orbiting groove to the other-direction orbiting groove when the clutch drum and the clutch case are relatively rotated in the other direction with the moving objects (40a, 40b) located in the one-direction orbiting groove; and at least one stop part capable of stopping the moving objects (40a, 40b), wherein when the moving objects (40a, 40b) are stopped by the stop part, relative rotation between the clutch drum and the clutch case in the one direction is restricted; a one-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the one direction; an other-direction orbiting groove in which the moving objects (40a, 40b) orbit when the clutch drum and the clutch case are relatively rotated in the other direction; and at least one return groove that guides the moving objects (40a, 40b) from the one-direction orbiting groove to the other-direction orbiting groove when the clutch drum and the clutch case are relatively rotated in the other direction with the moving objects (40a, 40b) located in the one-direction orbiting groove; and the clutch apparatus is configured such that at least two of the moving objects (40a, 40b) are stopped by the stop part at different timings, and the clutch apparatus has at least one of configurations 1) and 2), wherein in configuration 1) the moving objects (40a, 40b) are disposed on a single guide groove, and in configuration 2) the guide groove includes a plurality of guide grooves (21A, 21B) and each guide groove includes at least one moving object (40A, 40B).
