  • the outer lever 8 rotates in the releasing direction (upwards in Fig. 2 ), whereby the first and second sub-levers 15, 16 move upwards, and the releasing abutment portion 161 of the second sub-lever 16 is brought into abutment with the opening lever 6.
  • both the first and second inner levers 9, 10 rotate in the releasing direction, whereby the abutment portion 102 of the second inner lever 10 is brought into abutment with the outer lever 8, and by this action, the outer lever 8 also rotates in the releasing direction, and as when the outer handle is operated to open the door, the door can be opened.
  • the drive of the locking/unlocking and double locking motor 18 is transmitted to the second locking lever 14 via the worm 181, the worm wheel 17 and the small diameter gear portion 171.
  • the second locking lever 14 rotates about the pivot 131 from the unlocking position shown in Fig. 2 to the locking position shown in Fig. 3 .
  • the rotation of the second locking lever 14 is transmitted to the first locking lever 13 via the double locking control pin 23, and is also transmitted to the second sub-lever 16 via the first sub-lever 15 and the spring 26.
  • the double locking switching lever 20 moves to the locking position by virtue of the biasing force of the spring 27, whereby the first and second sub-levers 15, 16, the first and second locking levers 13, 14 and the lock knob 5 move to the locking positions, respectively, whereby the locking state shown in Fig. 3 results.
  • the lock knob 5 When the locking state is being produced as is shown in Fig. 3 , the lock knob 5, the first and second locking levers 13, 14 and the first and second sub-levers 15, 16 are held in the locking positions, respectively, and the releasing abutment portion 161 of the second sub-lever 16 is in a position where the releasing abutment portion 161 is unable to be brought into abutment with the opening lever 6.
  • the childproof locking sector gear 11 and the childproof locking lever 12 are held in the unlocking positions, the double locking switching lever 20 is held in the locking position, and the double locking control pin 23 is held in the connecting position.
  • the inner handle 4 When the inner handle 4 is operated to open the door from the locking state as shown in Fig. 3 , through double acting operations, that is, through the first door opening operation of the inner handle 4, the locking state is changed to the unlocking state, and through the second door opening operation of the inner handle 4, the door can be opened.
  • the first and second sub-levers 15, 16 are caused to move upwards, whereby the first and second locking levers 13, 14 are caused to rotate towards the unlocking positions, and a rear edge of the releasing abutment portion161 of the second sub-lever 16 is brought into a front end of the opening lever 6. Because of this, the second sub-lever 16 stops before the unlocking position. In contrast to this, the first sub-lever 15 is activated in association with the movement of the second locking lever 14 towards the unlocking position, moves from the locking position to the unlocking position against the biasing force of the spring 26 with the second sub-lever 16 left staying before the locking position.
  • the door can be opened in the way that has been described above.
