A riveter includes a casing having a passageway therein. A shaft is received in the passageway of the casing for a reciprocation motion. Jaws are received in the passageway of the casing to be moved along with the shaft. A spindle is inserted into a rear end the casing to be spun for driving the shaft for the reciprocation motion. The casing is provided with slots on a sidewall of the passageway, and the shaft is provided with recesses aligned with the slots respectively. In each pair of the slot and the recess, at least a ball is received to reduce a friction of the reciprocation motion of the shaft. The riveter of the present further provides an ejector behind the jaws. When a blind rivet is inserted, it will compress the ejector, and the ejector will eject the residual rivet out.
