Abstract
A length measuring device is used for measuring a length of from a virtual intersection of the extension lines of two surfaces extending along the respective sides A1, A2 to ends of the respective sides of a bent member. The length measuring device is comprised of a rotary body 20 rotating about the virtual intersection as a center O and a scale body 30 having graduations (divisions). The rotary body 20 has a contacting side 20c with which one side of the bent member A is brought into contact, while the scale body 30 has a contacting side 30c with which the other side of the bent member A is brought into contact. The two contacting sides 20c, 30c are arranged on straight lines drawn through the virtual intersection.
