PURPOSE: To surely grip a product by sticking a gripping rubber piece over the inside of a plate spring, whose upper side is connected to respective interval holding bodies, from the upper side to the lower end.

CONSTITUTION: When gripping bodies are brought close to each other by means of travel of a belt 3 so as to clamp a product W conveyed to the predetermined position by means of a conveying body T from the inside, a gripping rubber piece 11 is brought into tight contact with the inside of a gripping plate 9 according to a deflection of a plate spring 10. In addition, both of the plate spring 10 and the lower part, of the gripping rubber piece 11 are bent inward by means of a jaw piece (p) so as to hold the lower end of a product W, and the product W is prevented from dropping, so that a drop of the product W is prevented while the product W is moved to the upper side of a waiting pallet by means of rotation of a hand V. The gripping bodies are separated from each other by means of reverse travel of the belt 3 when the product W is positioned above the pallet, and the product W is smoothly and rapidly dropped onto the pallet from the gripping bodies with restoring force to the original form of the plate spring 10.
