PURPOSE:To increase the efficiency in welding work by arranging plural clamping claws on the slider for blank holding at non-rotary side and by displacing selectively the holding position opposing to the blank. CONSTITUTION:A pair of sliders 8 are arranged in opposition by pinching the welding axial line respectively on a clamp base 7 and made slidable to a guide bar 9. The slider 8 of one part is connected with the piston rod of clamping cylinder 10 and both sliders 8 and linked via linking rod 11 and arm 13. Clamping claws 24, 25 are symmetrically arranged to a claw holder 20 by pinching the rotary center on the upper part of the slider 8. The claws 24, 25 are made displacable to the holding position and non-holding position against the blank via a locating pin. The claw changing is thus simplified and the arrangement time can be shortened, so the work efficiency is increased.
