PROBLEM TO BE SOLVED: To easily measure an inner diameter of three claws of a three-claw chuck by providing a measuring tool body and a measuring rod body for measuring inner diameters of the three claws of the thee claw chuck, slidingly arranging three measuring rod bodies capable of abutting on the three claws in the radial direction from the center of the three claws in the measuring tool body, arranging an operation mechanism capable of mutually simultaneously slidingly adjusting the respective measuring rod bodies by the same dimension in the radial direction, and arranging an inner diameter display part capable of displaying the inner diameter according to a slide quantity of a ruler rod body. SOLUTION: This inner diameter measuring tool is formed by providing the measuring tool body 1 and the measuring rod body 2 for measuring the inner diameters D of the three claws T of the three-claw chuck W, slidingly arranging the three measuring rod bodies capable of abutting on the three claws in the radial direction from the center O of the three claws in the measuring tool body, arranging the operation mechanism 3 capable of mutually simultaneously slidingly adjusting the respective measuring rod bodies by the same dimension in the radial direction, and arranging the inner diameter display part 4 capable of displaying the inner diameter according to the slide quantity of the ruler rod body.
