<p>PROBLEM TO BE SOLVED: To provide a ruler for marking-off which enables simple work of marking off attachment positions of U bolts without trouble of examining the pitch of U bolts by referring to a dimension table or calculating the length corresponding to 1/2 of the pitch.SOLUTION: The ruler 1 for marking-off is configured so as to include a flat body 10 having a first side 11 and a second side 12 arranged at a right angle to each other and a hole part 20 penetrating the body, have a plurality of outer peripheral part parallel sides 21 in parallel with the first side and a plurality of outer peripheral part connection sides 23 connecting adjacent outer peripheral part parallel sides together in the outer periphery other than the first and second sides and a plurality of inner peripheral part parallel sides 31 and 32 in parallel with the first side and a plurality of inner peripheral part sides 33 connecting adjacent inner peripheral part parallel sides together in the inner periphery of the hole part, with the outer peripheral part parallel sides and the inner peripheral part parallel sides each corresponding to different U bolts of a single specification and their distances from the first side being equal to 1/2 of the pitch of U bolts of a corresponding specification.</p> |
