PURPOSE:To make it possible to perform the marking off work and to measure the size in an arbitrary slant direction, by providing rotary bodies which support struts so that said bodies are freely rotated with respect to a base, and rotating the rotary bodies by angle adjusting device. CONSTITUTION:A concave part 12 having a cylinder shaped internal surface is provided in a base 11 which is mounted on a flat plate 7. In the concave part 12, the first rotary body 15, the second rotary body 16, and the third rotary body 17 as an adjusting body are inserted so that they are aligned on the same central axis one another and can be freely rotated independently. The third rotary body 17 is fixed by an angle adjusting screw 35 which is engaged with a gear part 34. The struts 25 and 26 and the like can be inclined to the desired slant angle by directly holding the struts 25 and 26. In this constitution, the marking off work and the measurement of the size can be performed with respect to the arbitrary slant direction. |
