PURPOSE: To enable reliable suction carriage even of an inclining material, in a material transfer device employing a sucker suspension rod, by fixing suckers bendably in random direction to a sucker suspension rod and a slide rod through a ball joint.
CONSTITUTION: A sucker 39 is fixed through an inclined C-type bracket 24 and a ball joint 21 to the lower end of a sucker suspension rod 19 inclinably in random direction, and the sucker suspension rod 19 is fixed movably up and down to a lifting/lowering frame 17 The sucker 39 is fixed through a ball joint 35 to the lower end of a slide rod 31 fixed rollably and movably up and down to the lifting/lowering frame 17. When the lifting/lowering frame 17 is lowered and the suckers 39 contact with the outer face of a work W, respective suckers 39 incline on the surface of the work W and contact tightly therewith. Consequently, even an inclined or stepped work W can be carried reliably.
