Abstract
A dimension measuring device 100 in accordance with the present invention includes an end face following mechanism 1 that butts against an end face E of a long material, a dimension measuring mechanism 2 for measuring the dimensions of the long material, and a pushingly moving mechanism 3 for pushingly moving the end face following mechanism toward the end face of the long material. The end face following mechanism includes a plurality of contact sensors for detecting a contact state, and is turnable around two axes intersecting at right angles with each other. The pushingly moving mechanism pushingly moves the end face following mechanism into the state in which the plurality of contact sensors detect that the end face following mechanism butts against the end face of the long material. The dimension measuring mechanism is pushingly moved integrally and is turnable integrally with the end face following mechanism, and measures the dimensions of the long material when it is detected, by the plurality of contact sensors, that the end face following mechanism butts against the end face of the long material.
