The contact piece 3 has a through hole 17 having a round hole shape, and a pair of regulating projections 18 are provided on both sides of the through hole 17 by cutting and raising so as to project upward. The screw member 6 such as a bolt has a head 5 at the upper end, and the screw member 6 is inserted into the through hole 17 from above the contact portion 3. A tightening body 7 is disposed below the contact portion 3. The screw member 6 is screwed into a female screw hole provided in the center of the tightening body 7, and the tightening body 7 is detachably mounted on the screw member 6. It is. A spring 10 such as a coil spring as an urging member is disposed on the outer periphery of the screw member 6 between the contact portion 3 and the tightening body 7,
The fastening body 7 and the screw member 6 are urged by a spring 10 so as to protrude downward. A pair of tightening claws 8 are arranged on the tightening body 7, and the pair of tightening claws 8 are mounted by caulking pins 9 so that the tightening claws 8 can rotate freely within a predetermined angle range. The fastening claw 8 can be freely opened and closed. The caulking pin 9 is composed of a head 9a and a shaft 9b. The guide piece 4a is inserted between ends of the shaft 9b of the pair of caulking pins 9 on the head 9a side. 4a guides the vertical movement of the tightening body 7.

The mounting block A is attached to the steady rest 1
In order to make it possible to temporarily attach the steady rest 1 with one touch and attach it, the following procedure is performed. The screw member 6 is removed from the tightening body 7, the hardware 12 is arranged below the mounting portion 2 of the steady rest 1 as shown in FIG. 3A, and the contact portion 2 is mounted as shown in FIG. 2 and a pair of regulating projections 18

By attaching the mounting block A to the steady rest 1 as described above, the existing steady rest 1 of a normal specification can be temporarily fixed and attached with one touch. As a result, it is possible to use the current steady rest 1 of the normal specification without preparing a special steady rest, which is advantageous in terms of manufacturing, and when the work is made to have the same appearance as the current steady rest 1. It looks good. Further, when the abutment portion 3 is overlapped under the attachment portion 2 of the steady rest 1, the abutment portion 3 and the like are not visible in appearance when attached to the grooved rail member 11, and the steady rest 1 and the abutment portion 3 etc. The appearance can be improved even if there are differences in surface treatment (painting, plating, material, etc.). In addition, since the regulating protrusion 18 of the contact portion 3 can be locked in the through hole 13 of the mounting portion 2 of the steady rest 1 to stop rotation, the contact portion 3 rattles or rotates with respect to the mounting portion 2. The anti-sway fitting 1 can be firmly attached. Also, since the rotation can be stopped by locking the regulating projection 18 in the through-hole 13, the rotation can be stopped even if there is a difference in the shape and dimensions of the steady rest 1, and the mounting of the various steady rests 1 can be supported.

FIGS. 5 and 6 differ from the above example in the shape of the steady rest 1, and the mounting block A is attached to the attaching portion 2 of the steady rest 1 as in the above example. The rising portion 15 of the steady rest 1 is provided with a bent portion 15a bent in a V-shape. The steady rest 1 to which the attachment block A is attached in this manner is also attached to the grooved rail member 11 in the same manner as described above.

As described above, the steady rest 1 is attached to the grooved rail member 11 by the mounting block A. However, when the steady rest member 1 is removed from the grooved rail member 11, the screw member 6 is loosened. As a result, the steady rest 1 and the mounting block A are rotated by 90 ° with respect to the grooved rail member 11, and the mounting block is pulled upward from the opening between the lip portions 11a.

In the conventional example, as shown in FIG. 10, the diameter of the head 9a 'of the caulking pin 9' is small and the height of the head 9a 'is high, so that the combination with the guide plate 4' is poor. There is a problem that rattling is large. Further, since the diameter of the head 9a 'is small, it is necessary to insert the caulking pin 9' into the guide groove 4a 'of the guide plate 4' and hold the caulking pin 9 'from both sides. Also, in the removing operation, since the height of the head 9a 'of the caulking pin 9' is high and protrudes long, it cannot be removed by a vertical operation such as pulling out in a vertical direction as shown in FIG. FIG.
There is a problem that it can be removed only in a state of being inclined as shown in FIG.

Accordingly, the present invention employs the following structure. That is, the head 9a of the caulking pin 9 is formed in a disk shape having a large diameter and a low height. The guide plate 4 is provided with vertically elongated guide pieces 4a, and the shaft portions 9b of the pair of caulking pins 9 are provided.
The guide piece 4a is inserted between the ends on the side of the head 9a. Further, the slide portion of the guide plate 4 with the guide piece 4a was set so as to have a small gap in the thickness direction of the guide piece 4a. By adopting the above-described structure, the guide plate 4 and the caulking pin 9 are not rattled, and can be smoothly mounted, so that a sense of security as a product can be obtained. Further, it is not necessary to remove the steady rest 1 by obliquely removing it as in the related art, and the detachment can be performed by a vertical operation as shown in FIG.

Although the above embodiment has been described with reference to the example of the steady rest 1 as an example of the support fitting, the present invention can be similarly applied to the attachment of various other support fittings.
