<work of draining valve drive>
In the state that spool 8 is located at initial position, as shown in Figure 2 and Figure 3, the switching part 511 of switching gag lever post 51 makes to pass
Driving wheel 32 overcomes the active force of force application part 52 and engages with castle wheel 31.
In the above-described state, when powering to driving source, the driving force of driving source is for example transferred to via transition gear etc.
The first part of linkage part 41 and make first part's high speed rotation, whereby, second part is followed because of electromagnetic action to be rotated, from
And drive braked wheel 421 rotate so that the braking parts 4212 of braked wheel 421 contacted with control sheet 4221 (at this point, first part at
For idling conditions), prevent transition member 422 from rotating, so that the gear ring 35 of output clutch 3 be prevented to rotate.
On the other hand, the driving force of driving source is transferred to driving wheel 32 via castle wheel 31, is then transferred to and driving wheel
The planetary gear 33 that 32 sun gear portion 321 is engaged, at this point, since the rotation of the gear ring 35 of output clutch 3 is prevented from,
Therefore pinion frame 34 rotates, to drive the transition gear TG rotation engaged with the pinion part 3411 of pinion frame 34
Turn, and then the rotating output member 6 engaged with transition gear TG is driven to rotate, pulls on component 7 and be wound in rotating output member 6
Band wheel portion 62, make spool 8 driving be indexed to operating position, valve is opened.
When the driving of spool 8 is indexed to operating position, as shown in Figure 5, Figure 6, the switching part 511 of switching gag lever post 51 makes to pass
Driving wheel 32 is indexed to the position isolated with castle wheel 32 from the position engaged with castle wheel 31, and whereby, the driving force of driving source is not
It is transferred to spool 8 again.
