In the lump with reference to Fig. 5 and Fig. 6, an end that on the end of bar 54 that opens the door, is connecting the link rod 71 that opens the door, slide in the plane of the orthogonal axe that this link rod 71 that opens the door can be lock shaft 62 at the pivot center with knob lever 63, and can also in above-mentioned plane, rotate, rotate owing to the bar 54 that opens the door moves along with opening the door, the link rod 71 that opens the door just slides on the operating position of the lower position among Fig. 5 and Fig. 6 from Fig. 5 and off position shown in Figure 6.In addition, on the part corresponding with the link rod 71 of opening the door of above-mentioned lock shaft 62, formed the connection axial region 62a with non-circular cross-section shape, support bar 72 is entrenched in this and connects among axial region 62a.That is, support bar 72 and above-mentioned 63 coaxial connections of knob lever, and can rotate integratedly with knob lever 63.
In addition, on the axis direction of lock shaft 62, with above-mentioned support bar 72 position adjacent on arranged securing rod 73, this root securing rod 73 is installed on the lock shaft 62, can relatively rotate.That is, and be mounted to the lock shaft 62 that becomes one with knob lever 63 and can not carry out support bar 72 in relative rotation, can relatively rotate with securing rod 73.In addition, on lock shaft 62 and ends knob lever 63 opposite sides, cylindrical shape lever 74 has been installed, cylindrical lock just is connected on this root cylindrical shape lever 74.
Insert between support bar 72 and the securing rod 73 open the door another end of link rod 71, the slotted hole 76 that engagement pin 75 on the fore-end that is arranged on securing rod 73 is passed and engage with it is arranged on another end of the above-mentioned link rod 71 that opens the door, and extends very longly along the length direction of the link rod 71 that opens the door.And the engagement pin 75 that passes slotted hole 76 can contact with above-mentioned support bar 72 from non-locked position one side.In addition, the two ends of torque spring 77 are passed and are fastened on support bar 72 and the securing rod 73.By means of this structure, when lock shaft 62 from non-locked position when latched position is rotated, because the engagement pin 75 supported bars 72 of securing rod 73 are pushed down, so securing rod 73 directly drives rotation by support bar 72, and when lock shaft 62 from latched position when non-locked position rotates, support bar 72 pass to securing rod 73 to the rotation of non-locked position one side by torque spring 77 from latched position.
So the link rod 71 that opens the door just is in maintenance lock-out state position (position among Fig. 5) under the state of latched position at securing rod 73, and securing rod 73 is between the state position that unlocks (position among Fig. 7) under the state of non-locked position and rotates.
On the link rod 71 that opens the door, protrude and be provided with the engaging protuberance 78 that engages arm 40a engaging that can be had with pawl bar 40, this engaging protuberance 78 is to be arranged on like this on the link rod 71 that opens the door: be at the link rod 71 that opens the door under the state that keeps the lock-out state position, link rod 71 slides along with the rotation of the opening door operation in the bar 54 response compartments that open the door even open the door, and also can not contact, engage with the engaging arm 40a of pawl bar 40; And be under the state of the state position that unlocks at the link rod 71 that opens the door, the link rod 71 that then opens the door and contacts with the engaging arm 40a of pawl bar 40 and engages with it just because the rotation of the opening door operation in the bar 54 response compartments that open the door is slided.
; when knob lever 63 and securing rod 73 are under the state of latched position; the link rod 71 that promptly opens the door is under the state that keeps the lock-out state position; on the bar 54 that opening the door with outer side handle 56 or interior side handle, apply under the state of opening door operation power; when carrying out the operation of hook knob or using the unlock operation of no key port; rotation by means of the bar 54 that opens the door; the link rod 71 that opens the door slides under the state of securing rod 73 1 sides, and securing rod 73 is just along with knob lever 63 turns to non-locked position and rotates from latched position.As shown in Figure 8, in the middle of the process that the rotation and the sliding action of this link rod 71 that opens the door carries out, open the door the engaging protuberance 78 of link rod 71 and a contacts side surfaces that engages arm 40a along the axis of pawl bar 40, the link rod 71 that opens the door can not turn to the position of the state of unlocking, therefore, securing rod 73 can not turn to non-locked position yet, and the support bar 72 that rotates with the knob lever 63 that turns to non-locked position is absorbed by torque spring 77 with relatively rotating then of securing rod 73.
Then, the drawing of side handle 56 or interior side handle operation outside stopping, when failing opening door operation power on the bar 73 that opens the door, the elastic force of bar 54 by means of torque spring 55 turns to original position along with opening the door, link rod 71 also slides and gets back to original position though open the door, but in the process that this returns, the link rod 71 that opens the door makes engaging protuberance 78 contact with the side slip of engaging arm 40a, when the bar 54 that opens the door is got back to original position, as shown in Figure 7, owing to absorbed the elastic force of the torque spring in relative rotation 77 between securing rod 73 and the support bar 72, the link rod 71 that opens the door make its engaging protuberance 78 turn to can with the position that engages arm 40a engaging on, so the link rod 71 that opens the door just is in the position of the state of unlocking.
Therefore, when outside the operation once more when side handle 56 or interior side handle, the link rod 71 that opens the door that is in the state position that unlocks just moves by means of the rotation of the bar 54 that opens the door, and 78 pushing engaging arm 40a rotate it with the engaging protuberance, and ratchet 39 is disengaged with engaging of hook 38.
