PURPOSE:To avoid the mutual interferences of pawls, and to improve the stability of the holding of a part and the accuracy of centering by thinning one pair of two pairs of the pawls and making the holding areas of the pawls smaller than those of other pawls. CONSTITUTION:A pair of pawls 1a of two pairs of pawls 1a, 1b are thinned, and the holding areas of the pawls 1a are made smaller than those of other pawls 1b. When a rectangular parallelopiped electronic part is gripped by the pawls 1a, 1b, the long sides are gripped by the pawls 1b having large holding areas and the short sides by the pawls 1a having small holding areas. Accordingly, the mutual interferences of the pawls can be avoided, the gripping of the part is stabilized, and the accuracy of centering is improved. |
