And a locking hole 48 that can be rotatably locked. or,
The hook 42 has a hook-shaped stopper engaging portion 42a which can be engaged with the stopper 15 when the hook 42 is rotated around a locking hole 48 which is a center of rotation at one end, and is provided with a pivot center at the other end. An arm-shaped stopper pressing portion 42b is formed so as to be able to press the contact portion 16 provided on the stopper 15 when rotated about a certain locking hole 48. In the hook 42, the locking portion 47 is locked to the locking portion 46 b of the hook base 44, and the locking hole 48 can be rotatably locked to the arm 22 by the hook pin 28. The arm 22 is rotatably locked, and is rotatable with the arm 22. The hook 42 is always urged in the direction of arrow C by the urging means 50 around the hook pin 28 because the urging means 50 is interposed between the hook pin 28 and the engaging hole 48 with the urging means 50 interposed therebetween. Therefore, the hook 42 is connected to the hook base 4
4 is rotated in the direction of arrow D by the locking portion 46b to move against the urging force of the urging means 50, and is rotated around the hook pin 28 in the direction of arrow D.

The hook 42 thus constructed is fixed to the stopper 15 with the opening 12 fully open while being attached to the arm 22 and guided by the lower guide rail 13. The position at which the hook 42 is attached to the arm 22 is determined when the slide door 21 has the opening 12 fully opened.
2a can be locked with the stopper 15, and when the stopper locking portion 42a rotates around the hook pin 28 to release the locking with the stopper 15, the stopper pressing portion 42b of the hook 42 This is the position where the contact portion 16 is pressed. Furthermore, the stopper 15 is provided so that the relative position between the locking portion of the hook 42 and the rotation center of the hook pin 28 which is the rotation center of the hook 42 is parallel to the moving direction of the slide door 21. Since the hook 42 and the stopper 15 are configured to have such a relative positional relationship in the locked state, the force that locks the slide door 21 acting on the locked portion between the hook 42 and the stopper 15 always slides. Since it works only in the moving direction of the door 21, rattling due to vibration or the like is eliminated. Assuming that the relative position between the locking portion of the stopper 15 and the hook 42 and the center of rotation of the hook pin 28, which is the center of rotation of the hook 42, moves the slide door 21 as shown in the conventional example (FIG. 7). When the hook 42 is locked with a direction and an angle, the force of the hook 42 fixing the slide door 21 acts on the locking portion between the hook 42 and the stopper 15 and the rotation center direction of the hook 42 to slide the slide door 21. The force to prevent the force from being applied acts in the slide direction, and the other force is generated in the direction perpendicular to the slide direction as a component force, which not only requires more force at the locking part than necessary, but also vibrates due to the effect of the component force Rattling due to the like and the like may occur. Also, in the present embodiment, “the locking portion between the stopper 15 and the hook 42 and the hook 4
"The direction of the relative position with respect to the center of rotation of the hook pin 28, which is the center of rotation of 2, is parallel to the slide door 21", as long as it has an angle of about 5 degrees as long as there is no problem such as rattling. It is assumed that the sliding direction is parallel to the sliding direction of the sliding door 21.

Next, the operation of this embodiment will be described.
The initial state is when the sliding door 21 fully opens the opening 12. By operating a door handle (not shown) provided on the slide door 21 and closing one end of the rotating means 31 so as to close the opening 12, the wire main body 33 of the rotating means 31 is pulled. Then, the wire body 33 locked by the hook base 44 pulls the hook base 44, and the hook base 44 rotates in the D direction. Then hook base 4
The hook 42 slidably and rotatably mounted on the hook 4 also rotates in the direction D around the locking hole 48 against the urging force of the urging means 50. Then, the hook 42 releases the engagement with the stopper 15. In this state, the hook 42 is
Is released, the slide door 21 becomes slidable. At this time, the stopper pressing portion 42 of the hook 42
b rotates in the direction of arrow E and presses the contact portion 16 of the stopper 15. Then, the arm 22 and the sliding door 12 move in the sliding door closing direction (the direction opposite to the arrow B) by the reaction force. The opening 12 is moved in the direction opposite to the direction B so as to be in the closed state, and is in the closed state.

When the opening 12 is to be opened, the slide door 21 in the closed state is slid and moved in the direction of the open state. Eventually, the hook 42 is always urged in the direction of arrow C, but comes into contact with the stopper 15 and moves further, so that the stopper 15 is rotated against the urging force. At this time, the rotation of the hook 42 is not hindered by the hook base 43 because the locking portion 46b formed in the hook base 43 is elongated. And the hook 42 is the stopper 1
5 and is locked with the stopper 15 to maintain the open state. In this embodiment, the hook portion 41 is provided below the arm 22. However, the hook portion 41 is not necessarily provided below the arm 22, and may be provided above the arm 22.

[0022]

Therefore, according to the present invention, when the slide door is closed, the stopper locking portion 4
2a releases the engagement with the stopper 15, and the stopper pressing portion 42b of the hook 42 is
6, the slide door 21 is moved to the stopper pressing portion 42b.
, So it is not necessary to pull the slide door hard when closing it, making initial operation easier.
The operating force can be reduced.
