It is possible to change the size of the gap sandwiched between one inner wall 23 and T1, T2, T4, T5 (T1 <T2 <T4 <T5). Although not shown in the drawing, the size of the gap sandwiched between the engagement surface and one inner wall of the open space can be changed by performing a combination with or without a spacer plate, as described above, for a total of eight patterns. Thus, the displacement position of the stop surface at each thickness can be obtained.

  Furthermore, although not shown in the figure, by configuring the shape of the adjustment block as a square with an equal length and width as a substantially cubic frame shape, the open space of Troyoke can be fitted as a square, The frame walls on the four sides of the adjustment block may be configured to have different thicknesses. That is, the gap dimension can be configured in four ways by rotating and fitting every 90 °, and there is no spacer plate.
