Title: CLUTCH UNIT
Abstract:
The present invention relates to a clutch unit and, more particularly, to a clutch unit capable of providing: a free state in which free rotation by external force is possible; and a controlled state in which rotation is driven by a motor such that rotation by external force is impossible. The clutch unit is characterized by comprising: a first housing having a groove that is recessed inward; a second housing which is inserted into the groove of the first housing and has one or more first circular arc parts that are formed protruding from one surface along the periphery; one or more first roller parts disposed between the first circular arc parts; and a first rotation transmitting part which is inserted into the second housing and rotates according to the rotation of the motor, wherein when the first housing is attached to the first roller parts, rotation by external force is impossible because the rotation is controlled by the first rotation transmitting part, and when the first housing is detached from the first roller parts, free rotation by external force is possible.
