<P>PROBLEM TO BE SOLVED: To provide dimension measuring tools capable of measuring a dimension between two points of a measuring object easily and accurately, even if an obstruction exists between the two points. Ž<P>SOLUTION: Each dimension measuring tool 10 includes a fixed part 11 to be coaxially fixed by screwing to the threaded part 6a of a bolt 6 protruded from a first L angle 4, a cylindrical shaft 12 provided vertically in the fixed part 11 so as to be coaxial with the threaded part 6a, and erected so that its tip surface becomes higher than a height of a second L angle 5 attached to the first L angle 4, and radial grooves 13 provided in a tip surface of the shaft 12 to lock the claw 8b of a tape measure 8. The fixed part 11 is formed into the shape of a hexagonal nut, and has a tapped hole 11a screwed with the threaded part 6a of the bolt 6. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
