Abstract

PURPOSE:To move works by the predetermined distance gradually without increasing a cost by reciprocating a conveyer body with a work thereon at such a speed as does not make the work slip on a going way and at such a speed as makes the work slip on a returning way. CONSTITUTION:When air is supplied to an air cylinder member 31, a connection rod is moved against a return spring, so that a transfer base with a work thereon is moved forward via a member 50 to be guided and a conveyer body 20. In this process, as the conveyer body 20 moves at such a speed as does nor make the work slip on the transfer base, the work moves integratedly with the transfer base. When the conveyer body 20 moves to the front side, a rear end flange 27 operates an air valve 33 to discharge the air inside an airing member 31 from a speed control part 36, and the connection rod is moved backward by the energizing force of the return spring. In this process, as the conveyer body 20 moves at such a speed as makes the work slip on the transfer base, the work slips on the transfer base, so that only the transfer base returns to the original position while the work remains at the moved position.
