  Hereinafter, details of the present invention will be described in detail with reference to the drawings showing embodiments thereof. In the figure, reference numeral 1 denotes a sliding door, which opens and closes an opening 3 formed between left and right wall surfaces 2 and 2. In the closed position of the sliding door 1, the stand 4 is disposed at a position adjacent to the rear surface of the end of the sliding door 1.

The vertical 4 is formed of a vertically extending pillar material, and is provided with a concave groove 5 that is perpendicular to the entire length on the front surface facing the sliding door 1, and the shielding member 6 can be projected and retracted in the direction of the sliding door in the concave groove 5. It is inset.
The shielding member 6 includes a base material 7 formed of a metal drawing material such as aluminum, and a shielding portion 8 formed of an elastic flexible material such as a flocking material or a rubber material. The gap between the sliding door 1 and the sliding door 1 is fixed over the entire length of the sliding door in the vertical direction. Further, a cam shaft engaging groove 9 that engages with an eccentric cam shaft 12c of the adjusting member A, which will be described later, is formed in the base member 8 along the vertical direction.

In the vertical 4, a mounting hole 10 is provided on a side surface thereof so as to penetrate the concave groove 5, and an adjustment member A is mounted in the mounting hole 10.
The adjusting member A is made of a synthetic resin material, and includes an outer cylinder 11 that is fitted in the mounting hole 10 so as not to rotate, and a rotating body 12 that is rotatably fitted in the outer cylinder 11.
The outer cylinder 11 is provided with concave and convex teeth 11a and protrusions 11b that prevent the outer cylinder 11 from rotating when fitted into the mounting hole 10 of the vertical 4 on the inner peripheral surface thereof.

The rotating body 12 includes a pair of left and right elastic claws 12a that are elastically engaged with the concave and convex teeth of the outer cylinder, and a rotating tool engaging groove 12b that engages a rotating tool such as a screwdriver is provided on the front surface. ing. The elastic claw 12a is formed integrally with the body of the rotating body 11, and is given an elastic force by the elasticity of the resin material. The elastic claw 12a is always elastically engaged with the concavo-convex teeth 11a to lock the rotation of the rotating body 11, but if a rotating tool is applied to the rotating body 12 using a rotating tool, the elastic claw 12a is locked. That is, when a turning torque equal to or greater than the elastic engagement force of the elastic claw 12a is applied, the elastic claw 12a moves backward and comes off from the concave and convex teeth 11a, so that the rotating body 11 can turn.
Further, an eccentric cam shaft 12 c is provided at the rear end portion of the rotating body 12, and this eccentric cam shaft 12 c is engaged with a cam shaft engaging groove 9 provided on the side surface of the base member of the shielding member 6. .

It is possible to provide a low cost with a simple configuration by integral molding without requiring a member.

Further, since the cam shaft engaging groove 9 of the shielding member 6 is formed along the side surface of the base material 8 along the vertical direction, the base shaft 8 is drawn with a metal drawing material such as aluminum and simultaneously cam shaft engaged. The groove 9 can be formed, so that it is not necessary to separately process the camshaft engaging groove, and the processing labor can be saved.
As shown in FIG. 8, the base member 8 of the shielding member 6 is provided with cam shaft engagement grooves 9 on the left and right sides so that the adjustment member A can be attached to the vertical 4 from either the left or right side. However, the cam shaft engaging groove 9 may be formed only on one side as shown in FIG.

  As mentioned above, although the typical Example of this invention was described, this invention is not necessarily limited only to the structure of said Example. For example, the number of the elastic claws 12a of the rotating body 12 is not limited to two, but may be three or more at regular intervals.
