When the runner base 13 is further pushed in, the lock edge 36 is accommodated in the hole of the connecting hole 17, so that the runner base 13 can be inserted into the connecting hole 17. Then, when the lock body 33 is inserted to the position of the engagement groove 19, each lock body 33 receives the biasing force of the spring 34 and returns to the lock position, so that the lock edge 36 is engaged and held by the engagement groove 19. Thus, the runner base 13 can be locked and fixed to the holder 10 inseparably. As described above, the runner base 13 and the holder 10 can be connected by a simple operation of inserting and inserting the runner base 13 into the connection hole 17.

  When the door panel 1 is removed, the release pieces 37 of the left and right lock bodies 33 are operated with the fingertips so as to approach each other. As a result, the lock body 33 is unlocked, and the lock edge 36 is separated from the engagement groove 19 and fits in the accommodating portion 31. Therefore, the runner base 13 can be extracted from the connection hole 17. Since the release piece 37 at this time is located in the space between the runner base 13 and the operation tool 50, as shown in FIG. 9B, the release piece 37 is operated by the abdomen of the fingertip that is operated in proximity. The tool 50 can be firmly grasped at the same time. Therefore, the runner base 13 can be easily pulled out from the holder 10 while being securely held. Compared with the conventional lock structure, the removal work of the runner base 13 can be performed in a stable state and easily.

  In the present embodiment, the operating tool 50 has a substantially hexagonal plate shape, but it is not necessary and can take various shapes. For example, it can be formed in a polygon such as a triangle or a rectangle, a circle, a cylinder, or a sphere. If necessary, it can be formed into a lever handle shape instead of a rotary operation type knob. The biasing means 34 can be constituted by a torsion coil spring or a compression coil spring.

  The vertical adjustment mechanism need not be formed using a bevel gear as a transmission element. For example, a vertical adjustment mechanism in which the rotation operation of the operation shaft 46 is converted into a vertical swing of the adjustment lever via a screw mechanism, and the runner shaft 12 is vertically displaced by the vertical displacement operation of the adjustment lever. In short, any structure may be used as long as it is a vertical adjustment mechanism that rotates the operation shaft 46 to perform vertical adjustment.
