The notch 52c has a pair of walls 52d and 52e orthogonal to the direction of the linear sliding operation of the active lever 55. The walls 52d and 52e engage with the pin 55a by the linear sliding operation of the active lever 52. And is arranged with respect to the pin 55a. Further, between the wall portion 52d and the wall portion 52e, the pin 55a is opened by the spring 55b of the cancel lever 55 such that the pin 55a comes out of the notch 52c by the clockwise rotation operation shown in FIG. The length is set so that the pin 55a does not engage with the pin 55a when the pin 55a comes out of the notch 52c. The length of the wall portion 52d is set so as to always engage regardless of the positional relationship between the pin 55a and the notch 52c. Accordingly, the linear sliding operation in one direction and the other direction of the active lever 52 is transmitted to the passive lever 51 via the cancel lever 55 by the engagement between the pin 55a and the wall portions 52d and 52e, and the active lever 52 and the passive lever And 51 perform a linear sliding operation integrally in the same direction. In addition, by rotating the cancel lever 55 so that the pin 55a comes out of the notch 52c, the one-way linear sliding operation of the active lever 52 can be performed by engaging the pin 55a with the wall 52e. The active lever 52 and the passive lever 51 perform a linear sliding operation integrally in the same direction in the same direction. However, the linear sliding operation in the other direction of the active lever 52 is performed by the pin 55a and the wall 52e. Since it is not engaged, it is not transmitted to the passive lever 51, and only the active lever 52 slides linearly (the active lever 52 swings with respect to the passive lever 51).
[0019]
As shown in FIG. 2, the driving mechanism 6 includes a motor 61 and is held on the base plate 8 via a bracket 82. The motor 61 of the drive mechanism 6 is connected to a disc-shaped output cam 62 via a speed reduction mechanism (not shown) composed of a plurality of gears. The output cam 62 is connected to the active lever 52 of the link mechanism 5 via a transmission link 63. Accordingly, the transmission link 63 is pushed and pulled by the rotation of the output cam 62 by the operation of the motor 61, and the active lever 52 performs a linear sliding operation.
[0020]
As shown in FIGS. 2, 5, and 6, the lift lever 9 connected to the pawl 42 of the latch mechanism 4 is rotatably supported on the pin 42a. A first parallel lever 81 is rotatably supported by the pin 42a via a collar 84. A second parallel lever 82 is connected to the base plate 8 by the pin 82a substantially in parallel with the first parallel lever 81. It is rotatably supported. Further, a moving lever 83 is supported by the first parallel lever 81 and the second parallel lever 82 by pins 83a and 83b. The first parallel lever 81 is connected to the lift lever 9 so as to rotate the lift lever 9 by the rotation thereof, and is connected to the outside handle 11 (shown in FIG. 1) provided on the slide door 1. Have been. By operating the outside handle 11 to rotate the first parallel lever 81 clockwise as shown in FIG. 6, the movement lever 83 is moved by the action of the second parallel lever 82 to the position indicated by the solid line in FIG. , Without changing its posture, and the lift lever 9 rotates and the pole 42 rotates. The first parallel lever 81 and the second parallel lever 82 are constantly urged to rotate counterclockwise as shown in FIG. 6 by a spring 82b disposed around a pin 82a. The spring 81a disposed around the pin 42a always urges the lift lever 9 to rotate. The moving lever 83 has a rectangular hole 83c into which the pin 55a of the cancel lever 55 is inserted, and the moving operation of the moving lever 83 by the turning operation of the first and second parallel levers 81 and 82 causes the rectangular hole 83c to move. The wall 83d and the pin 55a are engaged with each other. As a result, the pin 55a is pressed by the wall 83d, and as a result, the cancel lever 55 rotates clockwise as shown in FIG. 4 so that the pin 55a comes out of the notch 52c.
[0021]
As shown in FIG. 4, an inclined contact wall 51f is formed in the pressing portion 51c of the passive lever 51. The latch lever 53 is disposed so as to be located on the movement trajectory of the tip of the contact wall 51f when the passive lever 51 linearly slides in the door open state C of the slide door 1, and in this state, the contact wall 51 f is configured to contact the latch lever 53.
[0022]
Next, the operation will be described.
[0023]
FIG. 4 shows the state of the link mechanism 5 in the door open state C, and this state is the initial position of each lever.
[0024]
In this state, when the slide door 1 is closed, the striker 7 and the latch 41 of the latch mechanism 4 are engaged, and the door is in the half-closed state B. At this time, since the latch 41 rotates, the latch lever 53 also rotates accordingly.
[0025]
When the sliding door 1 is in the door half-closed state B, and the state is detected by a sensor (not shown) such as a latch switch or a pole switch, the motor 61 is operated, and the output cam 62 is initialized by the operation of the motor 61. When the active lever 52 and the passive lever 51 are rotated by 180 ° from the position, the wall portion 52e of the active lever 52 pushes the pin 55a of the cancel lever 55 as described above, so that the active lever 52 and the passive lever 51 integrally move in the leftward direction in FIG. Performs linear slide operation. Thereby, as shown in FIG. 7, the pressing portion 51c of the passive lever 51 presses the latch lever 53, and the latch lever 53 rotates. As a result, the latch 41 also rotates with the rotation of the latch lever 53, and the slide door 1 enters the completely closed state C.
[0026]
After the slide door 1 is in the completely closed state C, the output cam 62 is further rotated by 180 ° to return to the initial position and returns to the initial position, and the active lever 52 and the passive lever 51 are also moved rightward as shown in FIG. It returns to the initial position by linear sliding operation. At this time, the passive lever 51 and the active lever 52 perform the return operation following the return operation of the output cam 62 mainly by the biasing force of the springs 51e and 52f, but do not function because the spring 51e and the spring 52f come off. Even in this state, the active lever 52 is reliably returned by being pushed by the transmission link 63 in the return operation of the output cam 62, and the passive lever 51 is configured such that the pin 55a of the cancel lever 55 is notched in the active lever 52. By being pressed by the wall portion 52d of 52c, the return operation of the active lever 52 is reliably performed following the return operation of the active lever 52.
[0027]
When the outside handle 11 is operated in the process of the slide door 1 moving from the door half closed state B to the door fully closed state C, the moving lever 83 moves and the cancel lever 55 rotates clockwise as shown in FIG. . As a result, the pin 55a of the cancel lever 55 comes out of the notch 52c of the active lever 52, and the engagement between the pin 55a and the wall 52e is released (the link between the active lever 52 and the passive lever 51 via the cancel lever 55 is disconnected. 7), only the active lever 52 continues the leftward linear sliding operation shown in FIG. 7, and the passive lever 51 stops the leftward linear sliding operation shown in FIG. As a result, the rotation operation of the latch lever 53 is stopped, and the operation of bringing the slide door 1 into the door completely closed state C is stopped. At this time, since the passive lever 51 is disconnected from the active lever 52, the biasing force of the spring 51e causes the passive lever 51 to linearly slide rightward in FIG. 7 and return to the initial position as shown in FIG. . When the outside handle 11 is operated, the lift lever 9 is also rotated to rotate the pawl 42 of the latch mechanism 4, so that the slide door 1 is brought into the door open state A by the rotation of the latch 41. At this time, the pressing portion 51c of the passive lever 51 is formed with an inclined contact wall 51f that can contact the latch lever 53 when the slide door 1 is in the open state, so that as shown in FIG. The latch lever 53 presses the pressing portion 51f by the rotation of the latch lever 53 accompanying the rotation of the latch 41 when the slide door 1 enters the door open state A. Thereby, the passive lever 51 reliably returns to the initial position regardless of the return operation by the spring 51f.
[0028]
In the arrangement of the link mechanism 4 in the door open state A of the slide door 1 shown in FIG. 4, the motor 61 operates and the active lever is activated even though the slide door 1 is in the door open state A due to erroneous detection of a sensor or the like. When the passive lever 52 and the passive lever 51 try to linearly slide in the left direction in FIG. 4, the contact wall 51f of the passive lever comes into contact with the latch lever 53 as shown in FIG. . As a result, the engagement of the passive lever 51 with the pressing portion 51c and the latch lever 53 is prevented. At this time, the pressing load due to the linear sliding operation of the passive lever 51 applied to the latch lever 53 from the contact wall 51c is directed to the pin 41a serving as the rotation center of the latch lever 53 from the inclination angle of the contact wall 51c with respect to the latch lever 53. become. Therefore, at this time, the latch lever 53 does not rotate due to the pressing load.
[0029]

The turning operation of the latch lever can be canceled during the operation. In addition, the passive lever can be returned to the initial position in conjunction with the return operation of the active lever to the initial position by the constant engagement between the link lever and the power transmission unit, and the return operation of the passive lever to the initial position can be reliably performed. Can be done.
[0030]
Further, according to the present invention, the power transmission portion is formed by forming a notch in the other of the active lever and the passive lever that can receive the link lever having a pair of wall portions having different lengths. The structure is simple without any increase, and the cost can be reduced.
[0031]
Further, according to the present invention, the latch lever and the passive lever are engaged when the linkage lever and the power transmission unit are engaged, so that the latch lever is passively rotated by the rotation operation when the latch lever shifts to the door open state. The lever can be pressed, whereby the passive lever can be more reliably returned to the initial position.
