Therefore, the clamp fitting of the present embodiment also has the sensor 9 with the substantially semi-circular flanges 43b and 44b formed in the same direction of the outer frame member 43 and the core member 44.
Since the work such as the cable 9a and the like can be pressed and fixed, substantially the same operational effect as the fifth embodiment can be obtained.

In the first to sixth embodiments, when the support member 11 is pressed, particularly when the flange of the bent circular portion of the column mounting hole 11c is formed, the flange surface is beautiful. Since it is relatively difficult to process, a notch may be provided in a part and press processing may be performed.

As described above, since the supporting member, the outer frame member and the core member are manufactured by press working, the clamp metal fitting of the invention of claim 1 is a metal lump that is cut and processed. In comparison, processing is extremely easy and can be done in a short time,
The material is relatively small, light, and there is no extra material that is scraped off and discarded during cutting, making it extremely efficient, inexpensive, and suitable for mass production.

According to the clamp fitting of the second aspect of the present invention, the shearing force applied to the support or the like can be dispersed and the frictional force can be increased by the flange of the support mounting hole of the support member. It can be protected and can be fixed more firmly.

In the clamp fitting of the third aspect of the invention, the flange of the work mounting hole of the outer frame member can disperse the shearing force applied to the work and increase the frictional force. The mounting surface can be protected and the work can be more firmly fixed.

In the clamp metal fitting of the fourth aspect of the invention, the shearing force applied to the work can be dispersed and the frictional force can be increased by the flange of the work mounting hole of the core member. The mounting surface can be protected and the work can be more firmly fixed.

According to the clamp metal fitting of the fifth aspect of the present invention, the work of fixing the bolt to the core member is not required, and the clamp knob of the clamp knob is fixed when the workpiece is clamped and the support member is clamped to the column or the like. Since the bolt does not rotate due to rotation, positioning and mounting work can be performed very easily.

According to the clamp metal fitting of the sixth aspect of the present invention, the work clamp is fixed and the support member is fixed to the support post or the like only by screwing the bolt with the tightening knob into the screw hole provided in the core member. Since it can be worn, the positioning and mounting work can be performed very easily, which further facilitates the positioning and mounting work.

According to the clamp metal fitting of the invention of claim 7, the V-shaped pieces of the work mounting holes of the outer frame member and the core member are used.
As long as the work can be inserted into the work mounting hole, the work can be pressed and fixed regardless of the outer diameter of the work, so the work can be mounted in a more reliable and stable state.
Versatility also increases.
