PCT No. PCT/SE78/00075 Sec. 371 Date July 10, 1979 Sec. 102(e) Date July 10, 1979 PCT Filed Nov. 13, 1978 PCT Pub. No. WO79/00291 PCT Pub. Date May 31, 1979 An apparatus for indicating inside dimensions comprises a base plate and a supporting plate spaced above the base plate for the object to be measured. Aligned rails displaceable in relation to each other are provided on the base plate and extend along slots in the supporting plate, said slots extending radially in relation to a center. Measuring arms project upwards from the rails through the slots which also form guides for securing supports for the object to be measured on the supporting plate. The rails are operatively connected to indicating members for transmitting measuring motion from the measuring arms to the indicating members.
