1. A selectable clutch comprising:
a first clutch mechanism and a second clutch mechanism for transmitting and interrupting rotation between coaxial and relatively rotatable first and second shafts; and
an operating mechanism for switching actions of at least one of the first clutch mechanism and the second clutch mechanism, to allow switching between transmission and interruption of torque between the relatively rotatable first and second shafts,
the first clutch mechanism being configured to transmit rotation at any rotation angle via a locking member disposed between a first rotating element and a second rotating element,
the second clutch mechanism being configured to transmit rotation at a predetermined angle by engagement between a first engaging element and a second engaging element,
wherein the first rotating element and the second rotating element are an outer race and an inner race disposed to slide into one another in an axial direction,
the locking member is a plurality of cams, and
the first clutch mechanism includes the plurality of cams circumferentially arranged between the outer race and the inner race, and a biasing mechanism biasing the plurality of cams.
