る。One end of a head mounting plate 7 having a plate thickness t is locked to the head mounting plate supporting portion 3. That is, the head mounting plate 7 has the projection insertion hole 8 at one end and the screw hole 9 at the other end.
Heads 10 are provided on the upper surface of the head mounting plate 7 having a spring property. The projection insertion hole 8 and the screw hole 9 form a pair of holes of the head mounting plate 7. Further, one end of the head mounting plate 7 is brought into contact with the supporting surface 4 of the head mounting plate supporting part 3 and the projection 4a is inserted into the projection insertion hole 8 so that one end of the head mounting plate 7 is supported. to mount the head mounting plate height H 1 from the upper surface of the head plate 1 supporting surface 4 of the support unit, the height of H 2 head reference height regulating unit 6, the thickness t of the head mounting plate 7 Since the relation with H is set to H 1 −H 2 ≦ t−0.2, the head mounting plate 7 is in contact with the upper surface of the head reference height regulating portion 6 and is shown by the solid line in FIG. To lean. Therefore, the screw hole 9 of the head mounting plate 7
The screw 11 for adjustment is screwed into the screw hole 5, the screw 11 for adjustment is screwed into the screw hole 5 of the head plate 1, and the screw 11 for adjustment is screwed in to move the head mounting plate 7 downward. When the head mounting plate 7 is positioned substantially parallel to the head plate 1, the head mounting plate 7 having a spring property is obtained.
Can be bent with the head reference height regulating portion 6 as an intermediate fulcrum.

必ずしも必要ではない。Therefore, the inclination of the head 10 can be set by adjusting the adjusting screw 9 and the spring property of the head mounting plate 7.
Although the head reference height restricting portion 6 is formed on the head plate 1 in the above embodiment, the head reference height restricting portion 6 may be formed on the lower surface of the head mounting plate 7 so as to project therefrom. Alternatively, the head reference height regulating portion 6 may be provided separately from the head plate 1 and the head mounting plate 7, and this may be mounted by brazing or the like. Further, by setting the width dimension of the supporting surface 4 of the head mounting plate supporting portion 3 to H 3 and setting the width dimension of the end portion of the head mounting plate 7 supported by this supporting surface 4 to H 3 , Since the movement of the end portion of the head mounting plate 7 is restricted when the end portion of the mounting plate 7 is supported by the support surface 4, the protrusion 4a and the insertion hole 8 are not always necessary.
