You may make it the structure further provided with the latching part at the time of full opening in which the hole was formed.

  As described above, according to the present invention, the slide door can be stopped at a plurality of positions in the movement range.

  Hereinafter, an embodiment of a stopper mechanism for a sliding door according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a slide door 3 that opens and closes a door opening 2 formed on a side surface of a vehicle body 1 of a vehicle includes a front and rear direction (arrow) of the vehicle via roller units respectively corresponding to the upper rail 4 and the lower rail 5. A is supported so as to be movable (slidable).

  The upper rail 4 is fixed to the vehicle body 1 so as to extend along the upper edge of the door opening 2, and the lower rail 5 is fixed to the vehicle body 1 so as to extend along the lower edge of the door opening 2. The upper rail 4 and the lower rail 5 are parallel to each other, and the front end portions thereof are bent toward the inside (vehicle compartment side). As a result, the slide door 3 is guided so that the outer surface of the slide door 3 is substantially flat with the side surface of the vehicle body 1 in the movement when the door opening 2 is fully closed, and the opening direction (rear) from the fully closed position. In this movement, the vehicle body 1 is disposed outward from the side surface.

  A roller unit (not shown) corresponding to the upper rail 4 is provided at a predetermined upper position of the slide door 3 and includes one or a plurality of rollers that roll in the upper rail 4.

  2 and 3, the roller unit 7 corresponding to the lower rail 5 is provided at a predetermined position below the slide door 3, and includes an arm 70, a roller bracket 71, a pair of left and right horizontal rollers 72, and a vertical roller. 73 and the door side latching | locking part 74 are provided.

  The rear end of the arm 70 bent upward is attached to the slide door 3 and moves together with the slide door 3. The roller bracket 71 is attached to the lower end of the arm 70 and pivotally supports a horizontal roller 72 and a vertical roller 73 so as to be rotatable.

  The horizontal roller 72 rolls the inner surface of the lower rail 5 having an inverted U-shaped cross section in the extending (longitudinal) direction, and moves the slide door 3 along the lower rail 5. The vertical roller 73 is disposed between the left and right horizontal rollers 72, supports the load of the slide door 3, and rolls on the vertical roller rolling surface 101 in the extending direction of the lower rail 5.

  As shown in FIG. 4, the door-side locking portion 74 includes a fixed piece 700 fixed to the upper surface of the roller bracket 71, a movable piece 701 disposed so as to face the fixed piece 700, and a torsion coil spring 702. And. Each of the fixed piece 700 and the movable piece 701 is provided with a pair of shaft support holes at the end on the arm 70 side, and a support shaft 703 is communicated with both shaft support holes. Therefore, the movable piece 701 is supported by the fixed piece 700 so as to be rotatable via the support shaft 703.

  The torsion coil spring 702 is wound around the support shaft 703, one end of which is locked to the fixed piece 700, and the other end is locked to the movable piece 701. As a result, an urging force in the direction of arrow B acts on the movable piece 701, and the movable piece 701 rotates until its front part comes into contact with the upper surface of the roller bracket 71. Hereinafter, this state of the movable piece 701 is referred to as a lockable state.

  In this lockable state, the movable piece 701 is bent downward at the tip so that the movable piece 701 can be fitted into any of the locking holes 90 (details will be described later) provided in the vehicle body side locking portion 9. A hook portion 704 is provided. FIG. 4 shows a state in which the hook portion 704 of the movable piece 701 is engaged with the locking hole 90 in the lockable state.

  In the present embodiment, the vehicle body side locking portion 9 is formed by providing a portion that is bent and extended at a substantially right angle from the end edge in a predetermined range of the central portion of the lower rail 5. Of course, it is possible to manufacture and arrange separately from the lower rail 5.

  A plurality of locking holes 90 are formed in the vehicle body side locking portion 9 at predetermined intervals so as to be continuous in the longitudinal direction. The locking hole 90 is formed in a predetermined size at a predetermined position so that the locking hole 90 can be fitted to the hook portion 704 of the movable piece 701 of the door side locking portion 74 in the lockable state. The intervals between the respective locking holes 90 may be equal or unequal. In the present embodiment, the locking hole 90 is a through hole that penetrates the vehicle body side locking portion 9 in the thickness direction. When the through hole is formed in this way, the processing is easy and the cost can be reduced. It is also possible to form a recess into which the hook portion 704 can be fitted (that is, fitable) on the upper surface of the vehicle body side locking portion 9 instead of the through hole, and this can be used as the locking hole 90.

  When the hook portion 704 of the movable piece 701 is fitted into the locking hole 90 formed in the vehicle body side locking portion 9, the door side locking portion 74 is locked. If it does so, the roller unit 7 which supports the door side latching | locking part 74 will also be latched, As a result, the movement before and behind the slide door 3 will be locked.

  The procedure when the user wants to lock the slide door 3 at the position of the desired opening amount is as follows. First, the user moves the sliding door 3 while pulling the door lever 80 (see FIG. 5) to the position of the desired opening amount in the extension range of the vehicle body side locking portion 9 (that is, in the unlocked state). Let Then, the pulling operation of the door lever 80 is stopped (that is, in a lockable state), and the slide door 3 is moved slightly forward or backward. Then, the hook portion 704 of the movable piece 701 is fitted into the locking hole 90 formed at the position closest to the position where the lockable state is switched, and the slide door 3 is locked.

  Next, the full-opening locking portion 103 shown in FIG. 2 will be described. The fully opened locking portion 103 is a plate-like body provided on the rear end side of the lower edge of the door opening 2, and when the slide door 3 is fully opened, its movement is locked in cooperation with the door side locking portion 74.
