Face 151 contacts, it is also possible to contact with the second guiding face 152, and the first possible situation is：When power output member 1 is starting
When the moment of rotation is larger to the impulsive force of the extension 32, then intersection f will be contacted with the first guiding face 151, now, be prolonged
Contact for point between extending portion 32 and power output member 1, put more specifically between extension 32 and warp surface 151 and contact；When dynamic
When the moment for starting to rotate is less to the impulsive force of the extension 32, then intersection f will be with the second guiding face for power output 1
151 contacts, are linear contact lay between extension 32 and power output member 1 now, and more specifically extension 32 and second is guided
Linear contact lay between face 152；Second may situation be：After power reception part 3 completes to couple with power output member 1, when described
Beeline between intersection f and the first guiding face 151 more than intersection f and the second guiding face 152 longest distance when, no matter
When power output member 1 starts to rotate to the size of the impulsive force of extension 32 how, first guiding face 151 will be with intersection f
Contact, is still that point is contacted between extension 32 and the first guiding face 151 now.
When need to depart from active cell and driven unit couple when, the y along Fig. 4 A under external force first of power reception part 3
Move in direction so that extension 32 is coupled with the disengaging of guide channel 15, now, then move backward forward along power reception part 3
The vertical direction e in direction is the installation direction observation of handle box, and extension 32 is not also overlap with power output member 1, i.e., actively
After unit is coupled with driven unit disengaging, the shape with gap g is reverted between extension top surface 322 and drive shaft terminal surface 14
