The coil spring 24 is provided at the base end of the check arm 2 as described above, and its details are shown in FIG. The coil spring 24 is arranged around the shaft member 20 that rotatably supports the base end 21 of the check arm 2, and one end (not shown) thereof is fixed to the bracket 1 and
The other end is locked to a protruding portion 211 formed on the base end 21 of the check arm 2. That is, the plate surface of the bracket 1 is formed with a circular arc-shaped long hole 11 of a constant length concentric with the shaft member 20, and the projecting portion 211 has the check arm 2
Of the coil spring 24 extends from the base end 21 of the coil spring 24 and penetrates the elongated hole 11 from the lower side to the upper side.

As a result, the check arm 2 is urged to rotate clockwise in FIG. 4, and when the door body D1 is at or near the closed position shown in FIG. When the door body D1 is in the open position shown in FIG. 4, the door body D1 is closer to the surface 31.
It is rotated toward the inner surface of. In this case, since the protruding portion 211 of the check arm base end 21 is located in the elongated hole 11, the clockwise rotation of the check arm 2 is restricted by the protruding portion 211 contacting one end 111 of the elongated hole 11, Further, the counterclockwise rotation of the check arm 2 is restricted by the protruding portion 211 coming into contact with the other end 112 of the elongated hole 11.

In such a stopper structure, when the door body D1 is opened (arrow e in FIG. 1), the check arm 2 moves from the W position to the X position in FIG.
During this time, the check arm 2 is always in contact with the check bush 2 at its intermediate portion in the longitudinal direction while moving relative to the resin bush 422 (FIG. 3) of the regulating member 42, and the interior surface 3 of the body panel 3.
The rotation in one direction is restricted, and the metal roller 23 provided at the tip 22 moves to the guide wall 41 on the locus f. As a result, the check arm 2 causes the body panel 3 at the opening edge of the vehicle.

By providing the guide wall 41, it is possible to prevent the check arm 2 from interfering with the vehicle opening edge panel and the like without extending the guide wall 41 to the front side of the vehicle along the inner surface of the body panel 3 as in the conventional case. It is possible to downsize the entire stop.

When the door body D1 is further opened, the metal roller 23 comes into contact with the guide wall 41 and moves along the guide wall 41, whereby the check arm 2 is rotated toward the interior surface 31 of the body panel 3. Regulated. After that, the metal roller 23 is guided by the outer peripheral surface of the roller body 52 to deform the leaf spring body 6, thereby expanding the gap S1 between the outer peripheral surface of the roller body 52 and the tip portion 61 of the leaf spring body 6. And enters the engagement space S (Y position in FIG. 1).
Then, the metal roller 23 is locked by the leaf spring body 6, the roller body 52, and the stopper portions 44, 45 that have returned to their shapes by contacting the stopper portions 44, 45 of the bracket 4, and the door body D1 is opened by approximately 90 degrees. In this state, further opening operation is restricted.

When it is desired to open the door body D1 a little more to secure a space for loading heavy objects, the door body D1 is once returned in the closing direction to allow the metal roller 23 to escape from the engagement space S (see FIG. 5 arrow g), then the door body D1
1 is rotated in the opening direction again, the metal roller 23 is guided by the guide surface 461 and enters into the notch 46 and engages with the notch 46, and the door body D1 is opened at 90 degrees or more at the Z position in FIG. Further opening operation of the door body D1 is restricted.

When necessary, the door body D1 crosses the turnover point (point L in FIG. 2) and is in the fully open position (FIG. 2) as described above.
However, if the door body D1 rotates in the closing direction and crosses the turnover point due to a strong wind or the like, the door body D1 is swung all the way to the closed position by its own weight. It will move. Here, in the present embodiment, the check arm 2 has the base end protruding portion 211.
Since (FIG. 4) is located in the long hole 11 and its clockwise rotation is restricted, the door body D1 maintains an appropriate angle with respect to its inner surface during the closing operation of the door body D1. 90
When returning to the vicinity of the open position, the metal roller 23 of the tip 22 of the check arm approaches the notch 46 as shown by the solid line in FIG. 5 and enters the notch 46 as shown by the arrow i to engage with this. To meet. As a result, the closing operation of the door body D1 is blocked without returning to the closed position.
