Similarly to the vehicle body side bent portion 26, the door side retainer 24 has a door side bent portion (second bent portion) in which a sheet metal strip is bent in a trapezoidal shape toward the front pillar wall portion 16 side. 34 and 34 are formed vertically symmetrically about the center in the vertical direction of the band plate, and the door side retainer fixing portion 36 between the door side bent portions 34 and 34 is attached to the door frame wall 18 by bolting. Bolt holes 38, 38 are formed.

  A door-side guide surface (second guide surface) 40 is formed on the outer surface of the upper door-side bent portion 34, and the door-side guide surface 40 is inclined downward from the inside to the outside in the vehicle width direction of the vehicle body 1. When the door 2 closes the door opening 14, the door 2 comes into contact with the vehicle body side guide surface 32. As is apparent from FIGS. 4 and 5, the vehicle body side retainer 22 and the door side retainer 24 having such shapes are different from each other with the mounting direction to the front pillar wall portion 16 or the door frame wall portion 18 being symmetrical. It is the same product.

Here, the door side retainer 24 has a stopper (regulating member) 42 that prevents the door side bent portion 34 from climbing above the vehicle body side bent portion 26 when the door 2 closes the door opening 14. It is attached.
The stopper 42 is formed by bending a sheet metal rectangular plate into an L-shape in cross-section, and includes a stopper fixing portion 42a and a stopper abutting portion 42b bent substantially vertically from the stopper fixing portion 42a. Yes. The stopper fixing portion 42a is fixed to the surface of the fixing portion 36 of the door side retainer 24 on the side where the door side bent portions 34, 34 are bent by welding or bonding.

  On the other hand, the stopper abutting portion 42b protrudes to the side where the door side bent portions 34, 34 are bent, and the vehicle body side retainer 22 is abutted against the abutting surface 42c of the abutting portion 42b when the ride-up is prevented. The The stopper 42 has an L-shaped side surface in contact with or close to the back surface of the door-side guide surface 40 of the door-side bent portion 34, and the contact surface 42 c is in the vehicle width direction of the vehicle body 1. The abutting surface 42c is positioned like a continuous surface that is substantially perpendicular to the door-side guide surface 40.

Hereinafter, the operation of the swing door device 4 will be described.
First, as shown in FIG. 1, when the door 2 closes the door opening 4, the vehicle body side guide surfaces 32 of the four vehicle body side retainers 22 and the door side of the four door side retainers 24. The door-side retainer 24 presses the door 2 inward in the vehicle width direction via the vehicle body-side retainer 22 so that the door 2 is in the normal closed position.

  Next, when the swing arm 6 swings in the opening direction of the door 2 by the driving force of the opening / closing mechanism 8 by the driver's door opening operation, the vehicle body side guide surface 32 of the vehicle body side retainer 22 and the door side guide of the door side retainer 24 are opened. The surface 40 moves the door 2 downward by an amount that does not interfere even if the door 2 moves outward. Thereafter, since the auxiliary link 10 forms a parallel link with the swing arm 6, the door 2 moves along the side surface of the vehicle body 1 to the rear of the vehicle body 1 by the driving force of the opening / closing mechanism 8.

Next, when the driver closes the door, the swing arm 6 swings in the direction to close the door 2 by the driving force of the opening / closing mechanism 8, and the operation opposite to that when the door is opened is performed.
Specifically, when the swing arm 6 swings in the direction of closing the door 2, the door side retainer 24 moves in the vehicle width direction of the arrow below the vehicle body side retainer 22 as shown in FIG. As shown, the vehicle moves in the vehicle height direction indicated by the arrow so as to approach the vehicle body side retainer 22. Then, as shown in FIG. 8, when the door side guide surface 40 abuts on the vehicle body side guide surface 32, the door device 4 moves the door 2 inward in the vehicle width direction while lifting and moving the door 2 upward. The door 2 is locked in the normal closed position by pressing strongly against a weather strip (not shown) disposed in the inner peripheral portion of the door opening 14 and operating a lock mechanism (not shown) provided in the door device 4. .

  Here, when the door 2 is closed, the door 2 may be inclined in the vehicle front-rear direction, the vehicle width direction, or the like by an external force such as wind or the backlash of the parallel link mechanism, and as a result rise in the vehicle height direction. is there. At this time, if a door device that does not include the stopper 42 is used, the door side bent portion is moved in the vehicle height direction while the door side retainer 24 moves in the vehicle width direction as shown in FIGS. 9 and 10. 34 is located above the vehicle body side bent portion 26. In this state, when the door 2 is further moved inward in the vehicle width direction by the door device and moved upward in the vehicle height direction, the door side bent portion 34 is moved to the upper side of the vehicle body side bent portion 26 as shown in FIG. Ride completely.

  In a state in which the door side bent portion 34 rides on the upper side of the vehicle body side bent portion 26, the door side guide surface 40 is located on the upper side of the vehicle body side guide surface 32, and thus does not contact the vehicle body side guide surface 32. That is, the link mechanism is closed while the door 2 remains in the half door state in which the door 2 is not pressed to the inside of the vehicle body by the door side guide surface 40 and does not move to the normal closed position, and the lock mechanism is activated. In this state, there is no gap between the door 2 and the door opening 14, or even if it is a minute gap, the driver cannot see the half-door state and remains in the half-door state. There is a risk of starting the vehicle.

  On the other hand, in this embodiment, even if the state shown in FIG. 10 is reached, the side surface of the vehicle body side bent portion 26 of the vehicle body side retainer 22 contacts the contact surface 42c of the stopper 42 as shown in FIG. Therefore, the door side bent portion 34 is prevented from riding on the upper side of the vehicle body side bent portion 26, and as shown in FIG. 13, the gap G is formed between the door 2 and the door opening 14 in the half door state. To actively form.

As described above, in the present embodiment, the stopper 42 prevents the door side bent portion 34 from riding on the upper side of the vehicle body side bent portion 26, and between the door 2 and the door opening 14 in the half door state. The gap G can be positively formed, and the visibility in the half-door state can be greatly enhanced.
In addition, by actively forming the gap G, even if the vehicle starts running in a half-door state, it is easy for air or rainwater to enter the vehicle interior from the gap G, and wind noise is likely to be generated. The person can notice the half-door state immediately after the vehicle starts running. Therefore, a simple configuration in which the stopper 42 is provided on the door side retainer 24 can reliably detect the half door state without using an expensive and complicated half door detection device or a half door alarm system. The safety of the passenger and the reliability of the vehicle can be easily ensured.

Although the description of the embodiment of the present invention has been completed above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in this embodiment, the stopper 42 is provided on the door side retainer 24. However, the present invention is not limited to this, and a stopper (regulating member) 44 having the same configuration is attached to the vehicle body side retainer 22 in the same manner as shown in FIG. In this case as well, it is possible to prevent the door-side bent portion 34 from riding on the upper side of the vehicle body-side bent portion 26 and form the gap G in a half-door state.

The stopper is not limited to the shape of the stopper 42 as long as the door side retainer 24 is prevented from riding on the vehicle body side retainer 22, and various modifications are possible.
For example, as shown in FIG. 15, a gap G0 having a predetermined width larger than that in FIG. 12 is formed between the vehicle body side retainer 22 and the door side retainer 24 when the door side bent portion 34 comes into contact. A stopper (regulating member) 46 extending in the vehicle width direction as much as possible may be used. Thereby, the gap G between the door 2 and the door opening 14 in the half door state can be further increased. For example, if the width in the vehicle width direction is formed long like the stopper 46, the visibility of the half-door state can be further improved so as not to be a blind spot of the weather strip attached to the door opening 14. The state can be detected more reliably.

  Further, as shown in FIG. 16, when the door 2 closes the door opening 14, the door-side bent portion 34 is moved when the door 2 moves upward to the highest position H higher than in the case of FIG. A stopper (regulating member) 48 that extends in the vehicle height direction so as to abut may be used. Thereby, the door 2 and the door opening 14 in the half-door state are surely prevented by giving a margin to the amount of upward movement of the door and reliably preventing the door-side bent portion 34 from getting on the vehicle body side bent portion 26. The gap G can be reliably formed, the visibility of the half-door state can be further improved, and the half-door state can be detected more reliably.

  Further, as shown in FIG. 17, the stopper 42 is not attached to the position shown in FIG. 5 but is fixed by adhering or welding a fixing portion 42 a to the back surface of the door side guide surface 40 in the door side bent portion 34. However, it is possible to prevent the door side bent portion 34 from riding on the vehicle body side bent portion 26, and the stopper may be integrally formed with the door side retainer 24.

  Further, the shapes of the vehicle body side retainer 22 and the door side retainer 24 are not limited to the above-described embodiments and modifications. However, as in the above-described embodiment and modifications, the vehicle body side retainer 22 and the door side retainer 24 are bent into a trapezoidal shape from a sheet metal band plate to form the vehicle body side bent portion 26 or the door side bent portion 34. The number of parts and the cost of the door device 4 can be reduced by making the mounting direction with respect to the front pillar wall 16 or the door frame wall 18 different from each other symmetrically with respect to the vertical center of the strip. It is preferable that the half-door state can be reliably detected while reducing the above.

  Finally, the present invention can be applied not only to a swing door device but also to a slide device, and can be applied to a vehicle door device other than a bus.
