is formed into a shape, and a claw 4 for supporting one side of the head box is formed at the tip of the horizontal piece 3, and a mounting plate for attaching the auxiliary member 2 is formed at the center of the upper surface of the horizontal piece 3. A hole 5 is provided.
The auxiliary member 2 has a claw 6 at one end for supporting the other side of the head box and a guide surface 7 formed on the claw 6 for guiding the other side of the head box, and the other end engages with a tool such as a screwdriver. An operating piece 8 is provided for this purpose, and a long hole 9 is provided in the center for attaching the auxiliary member 2 to the main body member 1. Then, the studs 10 are inserted and fixed into the mounting holes 5 of the main body member 1 and the long holes 9 of the auxiliary member 2, and the auxiliary members 2
The auxiliary member 2 can be moved back and forth relative to the main body member 1 only when a large force is applied to the claws 4 and 6, as shown in FIG. was supported.

To attach the head box 11 to such a mounting bracket, engage the upper edge of one side of the head box 11 with the claw 4 of the main body member 1, and then lift the other side of the head box 11 upward, and the upper edge will assist. The head box 11 was supported and fixed to this mounting bracket by moving along the guide surface 7 of the member 2 while being elastically deformed and eventually elastically engaging with the claw 6. In addition, if a tool such as a screwdriver is applied to the operation piece 8 from this state and the auxiliary member 2 is pulled forward with respect to the main body member 1, the engagement between the claw 6 and the upper edge of the other side of the head box 11 is disengaged, and the head box is removed. 11 could be removed from this mounting bracket.
