ABSTRACT:
A measuring instrument in which a slider slidably attached to a main bar is urged in one sliding direction or in the opposite sliding direction by means of a spring, the urged direction of the slider being switchable, and a displacement between the jaw of the main bar and the jaw of the slider with respect to a preset reference position is displayed on a dial indicator, so that measurement of the internal dimensions as well as external dimensions can be performed under the action of a constant resilient force.
