PURPOSE: To provide a product holding device unliable to have a product dislocated even in the case of conveying the product as it is held.

CONSTITUTION: At the time of holding a product W, arms 5 provided at the end parts of a base member 1 are oscillated in the approaching direction. At this time, the distance between each supporting part 9 protruding from the base member 1, and a finger 8 provided at the tip of each arm 5 and having the slip-off stop face protruding in the mutually approaching direction is shortened, so that the product W is prevented from slipping off by the slip-off stop faces 8b of the fingers 8 and supported by the supporting parts 9. With conveyance performed in this state, the dislocation of the product W is not generated.
