Provided is a knock-in tool having a mechanism for driving a screwdriver in which it is possible to reduce wear. A knock-in tool 100 has: a rotating member 115 driven in a rotating manner by an electric motor 111; a screwdriver 130 for performing a knock-out operation on a knock-in member 161; a drive roller 120 for transmitting the rotation action of the rotating member 115 to the screwdriver 130; a support roller 123 that, together the drive roller 120, sandwiches the screwdriver 130; an urging member 151b for urging the support roller 123 toward the screwdriver 130 once the drive roller 120 and the support roller 123 have sandwiched the screwdriver 130, and a drive roller movement mechanism. The drive roller movement mechanism is configured so as to be capable of switching the drive roller 120 between a separated position in which the drive roller 120 is separated from the rotating member 115 and a knock-out position in which the the drive roller 120 is brought into contact with the rotating member 115 and drives rotation.
