PURPOSE:To make precision positioning performable only in a way of making a hand pallet go down, by installing each guide part of fitted parts in respective hand pallets, and embedding one side pin of both these guide parts free of movement in and out. CONSTITUTION:When a bearing 8 is fitted in a shaft 9, first, this bearing 8 is held between U-shaped grooves 4A and 4B installed in each of a pair of upper and lower hand pallets 2 and 3, Afterward, both these hand pallets 2 and 3 are made to go down and the shaft 9 is held by a bottom part of the U-shaped groove 4B of the hand pallet 3 and a pin 5, thus positioning takes place. Next, the bearing 8 is further made to go down via these hand pallets 2 and 3 and fitted in the shaft 9, then each of these hand pallets 2 and 3 is moved in vertical directions and opened, and both hand pallets 2 and 3 are retracted together with a hand body 1 whereby assembling work for the bearing 8 is completed.
