してはね上るように形成される（詳細構造省略）。 During machining, the cutting tool (not shown) is attached to the member 4.
The member 4 is supported on the back by the main body 2 as shown by the dotted line in FIG. 7, and is processed. The member 4 is formed so as to spring up around the pin 3 so as not to damage the machined surface of the workpiece by the cutting tool blade during the return process (detailed structure is omitted).

A slight gap 5 is required between them. This gap gradually becomes larger due to wear and the like due to long-term use of the tool holder 1. If the gap 5 becomes large, play will occur in the tool holder 1, and the member 4 will escape laterally by the amount of play, resulting in a problem that the straightness and parallelism of the workpiece will deteriorate. Furthermore, if there is backlash, high-load machining cannot be performed, resulting in the problem of lowering work efficiency.

形状に形成される。 As shown in FIGS. 1 to 3, the main body 20 fixed to the stationary side of the machine is formed into a U-shape. A spring-up member 40 (hereinafter referred to as member 40) is fitted into the U-shape of the main body 20 while being pivotally supported by the pin 3 or the like. The member 40 is formed of an upper half and a lower half with the pin 3 as the center, and the cross section thereof is approximately V-shaped as shown clearly in FIGS. 4 and 5, respectively.

の接触嵌合は開放される。 A metal fitting 6 is fixed to a position corresponding to the upper half of the member 40 of the main body 20. The member 4 is attached to the metal fitting 6.
A V-shaped portion 7 is formed in close contact with the V-shaped portion 40b in the upper half of the V-shaped portion 40b. In addition, as shown in FIG. 2, the V-shaped portion 40a, the U-shaped portion 20a, the V-shaped portion 40b and the V-shaped portion 7 are
are formed in a V-shape so that they are in close contact with each other while being held in the main body 20, that is, they are reduced in size with respect to the fitting direction. Therefore, when the member 40 springs up as shown by the two-dot chain line in FIG. 2, these contact fittings are released.

かつ安価に実施することが出来る。 With the above structure, there is no need to provide a gap 5 between the main body 20 and the member 40 as in the prior art.
Further, as described above, during processing, the main body 20 and the member 40 are more likely to bite together due to the wedge action due to the V-shape, and there is no risk of looseness even after many years of use. This ensures straightness and parallelism during processing and improves accuracy. Furthermore, as described above, since the main body 20 and the member 40 can bite into each other, powerful cutting is possible, and the work efficiency can be improved. Further, in this embodiment, the contact fitting portion between the main body 20 and the member 40 is formed into a V-shape, which is simple and easy to use.
And it can be implemented at low cost.
