も、イヤロッド又は描記ペンの方向は変わらない。The diameter of the second through hole is smaller than the diameter of the first through hole, and the support rod is provided with a groove parallel to the axis so that the tip of the first fixing screw enters into this groove. Therefore, when the support rod is inserted through the first and second through holes in common and the first fixing screw is tightened, the support rod is pressed and fixed to the inner peripheral wall of the first through hole, and the groove and the first through hole are fixed. 1. The rotation of the support rod is prevented by the cooperation with the fixing screw. As a result, the ear rod or writing pen is securely fixed in the plane containing the arcuate body. Further, even if the first fixing screw is slightly loosened to release the fixed state, the tip remains in the groove, so that the direction of the ear rod or the writing pen does not change even if the insertion depth of the support rod is changed.

る。Further, since the diameter of the third through hole is slightly larger than the diameter of the rod portion of the bite fork or the like, even if the third through hole is fixed to the arcuate body by tightening the third fixing screw, it is between the holding piece and the rod portion. If a force larger than the frictional force is applied, the bite fork or the like can be slightly moved within the plane including the arcuate main body, and the position can be adjusted.

きる。Since the Faith Bow of the present invention is constructed as described above, when inserting the ear rods 3, 3 into the ear canal for use, the fixing screws 204 are tightened and the fixing screws 207 are loosened to loosen the ear rods 3, 3. Can be easily adjusted to the proper position. That is, when the fixing screw 204 is tightened in the state shown in FIG.
a to prevent rotation of the support rod 203, and then the support shaft 201 is attached to the collar 202 by a stopper 205.
Is slid to the right until it comes into contact with the opposite end surface of the support 1a. Therefore, when the fixing screw 204 is fully tightened, the end surface of the collar 203 is strongly pressed against the opposite end surface of the support 1a, and the support rod 203 is not supported by the through holes 201a and 20a.
The support rod 203 is fixed to the main body 1 so that it cannot be slid with respect to the support shaft 201 and the collar 202 and cannot rotate together with the support shaft 201 and the collar 202, because the support rod 203 is strongly sandwiched between the opposing inner walls of 2a. To be done. or,
If the fixing screw 207 is tightened, the ear rod 3 becomes the support shaft 2
It is fixed at 06. In this case, the rotation of the support shaft 201 is prevented only by the frictional force due to the pressure contact between the end surface of the support body 1a and the opposed end surfaces of the collar 202 and the stopper 205, so that a further rotating force is applied to the support rod 203. Thus, even if the fixing screw 204 is tightened, the support shaft 201
It is possible to rotate the collar 202 slightly. This guarantees prevention of breakage and deformation of parts when an abnormal external force is applied to the first support device, and fine adjustment of the position of the ear rod 3. As is clear from the above description, by slightly tightening the fixing screw 204, the angle θ (FIG. 4) formed by the plane including the support rod 203 with respect to the plane including the arcuate main body 1 can be easily adjusted. Thus, adjustments such as matching the plane including the arched body 3 with the Frankfurt plane or the Campel plane can be easily and accurately performed with the ear rod 3 set in the ear canal.

If 2 is tightened, the holding piece 403 or 404 will be pressed toward the main body 1, so that the rod portion of the bite fork 5 (or the lower nose point indicating rod 6) will be strongly pinched and the holding piece 404 and The body 1 is strongly clamped by 405. Therefore, the bite fork 5 and the nose point indicating rod 6 can be fixed to the positions shown in FIG. In this case, since the diameter of the through hole 401a is selected to be slightly larger than the diameter of the rod portion of the bite fork 5 or the nose point indicating rod 6, the fixing screw 402 is tightened even when the fixing screw 402 is tightened. Lower end surface and the clamping piece 403
If an external force larger than the frictional force due to the pressure contact with the top surface of the tool is applied to the bite fork 5 and the nose point indicating rod 6, these can be finely moved. This guarantees fine adjustment of the posture of the bite fork and the nose point indicating rod after once set, and the position and inclination with respect to the plane including the arched body 1.

In both cases and when using the oral adjustment occlusal recording method, it can be used extremely simply, quickly and properly.
