The pin 40 has a round bar shape, and has a large diameter portion 401 provided with a large diameter at the center portion and small diameter portions 402 provided on both sides of the large diameter portion 401. Note that a stepped end surface 403 is formed at the end of the large diameter portion 401. The length of the large-diameter portion 401 substantially corresponds to the U-shaped inner space of the guide member 20. Large diameter portion 401,
The total length of the small-diameter portion 402 substantially matches the U-shaped outer space of the adjustment base 2. This pin 40

In order to manufacture this embodiment, an assembly work shown in FIGS. 8 to 10 is performed.

That is, as shown in FIG.
With the open side of the U-shape facing upward, the guide member 20
The pin 40 is pushed into the guide groove 201 from the front and rear ends of the pin. This work can be performed by a simple reciprocating motion of a robot arm or the like.

Next, as shown in FIG. 9, the slide member 30 is fitted face-to-face with the guide member 20 with the U-shaped open side of the slide member 30 facing downward, and the pin 40 is attached to the mounting groove 3 of the slide member 30.
01. This work can also be performed by simple lifting and lowering of a robot arm or the like.

As a result, as shown in FIG.
The end face 403 of the large-diameter portion 401 abuts on the slide member 30 to prevent the pin 40 from coming off in the axial direction. Also,
The pin 40 is surrounded by the guide groove 201 of the guide member 20 and the mounting groove 301 of the slide member 30 which are orthogonal to each other, and the pin 40 is prevented from rolling off. In other words, the pin 40
Thus, the guide member 20 and the slide member 30 are securely assembled.

Thereafter, if the seat plate 10 is fixed to the guide member 20 with the screws 50, the mounting of the fixing seat F is completed.

It is to be noted that the operation piece 6, which is attached to the shaft 8 of the adjustment base 2,
Regarding the assembling of the spring member 7, it is possible to work in a static state where no other movable member acts on the spring member 7,
It is machined by a simple operation of a robot arm or the like.

When this embodiment is used, the side plate-side mounting member D, which is the locked portion side, can be mounted and dismounted from the direction perpendicular to the side plate B with respect to the fixed seat F, which is the locking portion side. it can.

That is, as shown in FIG.
The curved inclined surface 51 of the locking groove 5 pushes the small diameter portion 402 of the pin 40 backward, and the curved small angle 52 of the locking groove 5 positions the small diameter portion 402 of the pin 40 to the rearmost side. At this time, the slide member 30 also retreats and slides synchronously (see FIG. 6).
Therefore, the pin 40 slides smoothly. The large-diameter portion 401 of the pin 40 on the rear side pushes the curved inclined surface 62 and the curved large angle 63 of the operation piece 6 against the pressing spring member 7 so that the operation piece 6
Is rotated (see FIG. 4).

As shown in FIG. 3, when the small diameter portion 402 of the pin 40 passes through the curved small angle 52 of the locking groove 5 and enters the circular arc portion 53 (slids in the opposite direction), the slide member 30 is also synchronized. And then slide back. At this time, the large-diameter portion 401 of the pin 40 on the rear side is pressed by the curved portion 64 of the operation piece 6 pressed by the spring member 7, and is pinched by the arc portion 53 of the locking groove 5 on the rear side. Will be locked.

To release the lock, the operation piece 6 may be rotated against the elastic pressure of the spring member 7. When the lock is released, the detachment is performed by the reverse operation described above.

As described above, in addition to the embodiment shown in the drawings, the runner for suspending and running the door plate is incorporated between the runner main body running on the rail and the support member fixed to the door plate, and the runner main body and the support member are mounted. It is also possible to put on and take off.
