  "textContent": "The present invention relates to a starter for an internal combustion engine, comprising a starter motor (1) whose output shalt (17) is rotated by current supplied; a torque transmission member (2) with a pinion (22) for transmitting torque from an output shaft (17) of the starter motor (1) to a ring gear (6) of the engine, and which is capable of transmitting and interrupting the torque by moving the pinion (22) so as to mesh with and disengage from the ring gear (6) ; an electromagnetic actuator (3) for moving the torque transmission member (2) to a place where the pinion (22) meshes with the ring gear (6) when current is supplied; a disengaging mechanism (4) for applying a driving force to the torque transmission member (2) so that the torque transmission member (2) moves to a place where the pinion (22) is disengaged from the ring gear (6) when the number of revolutions of the ring gear (6) exceeds that of the torque transmission member (2); the torque transmission member (2) is configured to slide on the output shaft of the starter motor (1); the torque transmission member (2) is comprised of: the pinion (22) mounted around an outer periphery of the output shaft (17) of the starter motor (1) ; a sleeve (21) mounted around the outer periphery of the output shaft (17) so as to be able to move in an axial direction while rotating together with the output shaft (17); and a one way clutch which is interposed between the sleeve (21) and the pinion (22) to transmit the torque only in a one-way rotational direction from the sleeve (21) to the pinion (22), and the torque transmission member (2) also transmits rotation from the pinion (22) to the sleeve (21) by sliding resistance in the one-way clutch; a first helical spline (112) is formed on the outer periphery of the output shaft (17) of the starter motor (1), a second helical spline (24) is formed on the inner periphery of the torque transmission member (2), and a helical spline engagement part is constituted by the first helical spline (112) and the second helical spline (24).",
