Abstract:
1. A clutch apparatus for performing two-phase position control for a two phase-positioned object installed on a shaft, the clutch apparatus comprising: a clutch housing for rotating together with the shaft, while supporting the shaft; a driving gear installed on the housing, for being rotatable and for selectively driving the housing in a rotatable manner with the help of a clutch intervened between the housing and the driving gear; and a solenoid unit for supporting the housing and selectively on/off-controlled, wherein the housing has an initial position controlling protuberance interfered with the solenoid unit in its on-state, for determining an initial position of the object, and a pair of phase protuberances interfered with the solenoid unit in its off-state, for suppressing rotation of the housing at each of the two phase positions of the object.
