To highly efficiently deliver a workpiece in a short period of time, and to employ even a conventional V-shaped receiving table.

A body 4 provided at a tip of an arm 2 is rotatably stored with a drum 10, the drum 10, on its outer circumference, is concentrically formed with a pair of first and second storage parts 20 and 21, the first and second storage parts can store workpieces between themselves and the inner face of the body 4, in a manner of being outwardly opened in the radial direction, and the body 4 is formed with an entrance 8 from which the upper end of the receiving table 24 can intrude in the body 4 and an air cylinder 16 for rotaionally controlling the drum 10. This constitution can deliver the workpieces between the receiving table 24 and the storage parts via the entrance 8 at a rotation position of the drum 10 where the first and second storage parts 20 and 21 coincides with the entrance 8 in phase, and retain the workpiece in the body 4 at a rotation position of the drum 10 where the first and second storage parts 20 and 21 is shifted from the entrance 8 in phase.
