To reduce the wearing of a jaw in a fitting tool for a blind rivet.
The tool is used for fitting the blind rivet of a type having the rivet body 2 and a mandrel 3 extended passing through this body 2 and provided with a prescribed breaking neck. This tool has at least three balls 27 in each line for one or more lines. The balls 27 are held in such degree as not to excessively bite the mandrel 3 by cooperating with the tapered part inserting the mandrel 3 in the rivet 1. At the time of moving the tapered part to the direction leaving the rivet body 2, the balls 27 are bitten to the mandrel 3 to hold the mandrel 3. At the time of continuing the further movement in the same direction, the rivet body 2 is widened and the mandrel 3 is broken at the prescribed neck for breaking. The ball device is not worn so quicker as the conventional jaw device.
