Abstract: A parts accumulating section includes a cylindrical center member; and a hose helically wrapped around the outer periphery of the cylindrical center member, and connecting two predetermined steps of a parts production line to each other. The hose has an inner diameter dimension which enables parts to pass, in a predetermined attitude, through the hose with only a respective one of the parts disposed in the hose in the radial direction of the hose. A vibration generating section applies torsional vibrations to the parts accumulating section so that the parts are fed through the hose. The parts discharged from the upstream step are accumulated in the hose in the same order as they are handled in the upstream step. The parts are fed through the hose without generating surface damage to the parts due to their collision against each other, and are supplied to the downstream step.
