Abstract: The present invention provides a small electric blind rivet setting device that is capable of being driven by a battery and that does not require a pathway for recovering the broken mandrels to be provided in the motor shaft. A recovery container 10 is provided in a tool housing 27 forward of an electric motor 13 in the axial direction, and a spindle 14, which rotates because of the rotation of a drive shaft 18 connected to the electric motor circumventing the recovery container, is connected so as to move a pulling head (30) in the axial direction. The positive rotation, stopping of rotation and reverse rotation of the electric motor are controlled by a pulling operation on a trigger and detecting the position of the pulling head in the axial direction.
