PURPOSE: To fix a work by fitting a guide pin to a guide hole provided in the work and to fixing holes provided respectively in a supporting platform and a table and to facilitate correction of rotational slippage by a rotation correcting means, which enables the supporting platform for supporting the work to rotate freely.
CONSTITUTION: A supporting platform 3 and a work 4 are arranged on a table 1 so that the position of the supporting platform 3 and the work 4 can be varied by moving an arm rod 2, and the work 4 is fixed in the fixed position by fitting a positioning pin 5 to a guide pin penetrating hole in the supporting platform 3 and to a guide pin fixing hole 6 formed in the table 1. A guide rail, which engages with a groove part, provided in the arm rod 2 freely slidably, is arranged projectingly on the end part bottom face of the supporting platform 3, and a fixing pin, which rotationally fixes its center, is arranged projectingly in the arm rod 2. The arm rod 2 is slid by screwing adjusting rods 8, 9, which are provided in the both end parts of the arm rod 2, forward/backward, so that rotation slippage in the work 4 can be corrected.
