A clutch apparatus 29 switches the transmission and the cutoff of the rotating force between a steering-wheel-side housing 76 and a tire-side housing 78. The clutch apparatus 29 is configured such that a first mode, a second mode and a third can be switched among these three modes. In the first mode, the rotating force is not transmitted between the steering-wheel-side housing 76 and the tire-side housing 78. In the second mode, the steering-wheel-side housing 76 and the tire-side housing 78 are being mutually locked in place and, in this locked state, the rotating force can be transmitted to for the rotation in the both directions. In the third mode, the transmission of the rotating force can be canceled such that while the rotating force can be transmitted, between the steering-wheel-side housing 76 and the tire-side housing 78, relative to the rotation in one direction, the rotation of either the steering-wheel-side housing 76 or the tire-side housing 78 in the other direction is allowed. |
