To provide a press-fitting device that reliably prevents a large load from being applied to a machine tool during press-fitting.
A press-fitting tool 20 includes a shank 30 integrally rotating along with rotation of a main shaft 11, a support member 40 rotatably supporting the shank 30, a driving member 50 integrally rotating along with the rotation of the shank 30, an arm 70 relatively movably supporting the driving member 50 in a front and rear direction of the shank 30 when the driving member 50 rotates and supported by the support member 40 via disk springs 75, 75, and a press-fitting head 60 integrally moving along with the movement of the driving member 50 and supporting a press-fitted component W1. The press-fitting tool 20 is mounted on the main shaft 11. An engagement section 70d of the arm 70 is engaged with a notch section 100a of a tool 100 so as to prevent the arm 70 from moving in a rear direction, and the press-fitting device 1 is moved in the rear direction. The press-fitted component W1 is press-fitted into a workpiece W while the support member 40 is separated from the arm 70.
