固定装置。 This is a drafting machine in which a vertical carriage for a drafting head or a scale is movably mounted on a vertical rail, and a pitch plate is formed by arranging engagement holes at equal intervals in the longitudinal direction of a long plate. A pitch plate is disposed on the rail surface of the vertical rail, and an engagement piece such as a swing claw provided on the vertical carriage is brought into elastic contact with the pitch plate so that the engagement hole and the engagement piece can be freely engaged and disengaged. In a drawing machine that facilitates the drawing of equally spaced parallel lines, a narrow width part 22 is formed by cutting out the side near the lower end of the pitch plate 21, and the pitch plate 21 is slid longitudinally onto the vertical rail 20. A clamping member 25 made of a push screw or the like is movably inserted loosely and fixed to the lower end of the vertical rail 20, and the clamping member 25 is formed so that both sides of the narrow width part 22 can be compressed. A pitch plate fixing device for a drafting machine, characterized in that the pitch plate 21 is fixed by finely adjusting the pitch plate 21 in the longitudinal direction of the vertical rail 20.
