要である。 2A and 2B show a shaft 23, and flat mounting portions 26, 26 are formed at both ends of the shaft 23 by cutting or pressing. Holes 27, 27 perpendicular to the axis are bored in the mounting parts 26, 26, and the screws 15, 15 are screwed into the holes 27, 26. Rising portions 22, 22 of the vertical carriage 5 shown in the figure
It goes without saying that the spacing between the holes 28, 28 is set to be the same as that of the holes 28, 28. Then, stepped portions 29, 29 are provided from the mounting portions 26, 26 toward the center, respectively, and the shaft 2
The drawing head 6 is formed to have a smaller diameter than the diameter of the drawing head 6 to prevent it from wobbling in the axial direction. That is, the distance C 1 between the inner ends of the stepped portions 29, 29 and the distance W 1 between the inner ends of the engaging pieces 16, 16 of the drafting head 6 are made to match, or the stepped portions 29, 29 are Engagement piece 1
The movement of the drafting head 6 is restricted by matching the distances C 2 and W 2 between the outer ends of the drawing heads 6 and 16, respectively. color 2
5 is provided with a slot 24, so even if the mounting parts 26, 26 of the shaft 23 expand and expand beyond the shaft diameter due to press working, it can be easily inserted, and an E-ring etc. for positioning the collar 25 can be inserted easily. No regulatory measures are required.
