When "off" state, and fixed gear 31 are changed into rotating freely, the load of draining valve 95 is applied to along the first transmission
The reverse transmission of group, until being passed to outlet side gear 23 (planet supporting gear 232).Draining is applied to by what is transmitted like this
The energy that the load of valve 95 is obtained is exported (consumption) by the idle running of fixed gear 31.Thus, draining valve 95 returns to original position
Put.
And, when cam wheel 25 returns to original position, the sector with the engaging protrusion 61 engaged with cam path 252
Handle 60 rotates towards the direction near cam wheel 25.Like this when fan-shaped handle 60 rotates, the upper electricity that fan-shaped handle 60 has
Motivation gear locking projection 62 leaves the locked projection 211 of upper motor gear 21.Thus, upper motor gear 21 is changed into fair
Perhaps the state for rotating.Also, it is inclined by towards the upper motor gear 21 of axis direction top force by compression helical spring 48
Cam is pressed and moved towards axis direction lower section.Be consequently formed is the upper holding section 2111 of upper motor gear 21 and rotor wheel
The lower holding section 525 in hub portion 52 engages, and the driving force of motor 10 is also delivered to the state of upper motor gear 21.
Like this, if stopping motor 10, the locking of fixed gear 31 of planetary gearsets is constituted because of tensile coil
The effect of spring 435 and be released from, the first transmission group is switched to "off" state by clutch.Thus, draining valve 95 is returned
To original position.
