Abstract: The present invention relates to a starter (1) for an internal combustion engine (2), comprising a support (4), an electric motor (5) which is arranged on the support(4)and which serves for driving a pinion (7) in rotation, and a solenoid drive (6) which is arranged on the support (4) and which serves for the axial adjustment of the pinion (7) between active position (AS), which is provided for the drive of a gearwheel (3) of the internal combustion engine (2), and a passive position (PS), which is axially offset with respect to the active position (AS), wherein the solenoid drive (6) has a plunger stop(20) which is static with respect to the support (4), a plunger (21) which is axially adjustable relative to the plunger stop(20), and a cylindrical coil arrangement (22) which is arranged on the plunger stop(20) and which surrounds a cylindrical coil interior (25) of the coil arrangement (22) in a circumferential direction,wherein said coil interior (25) extends axially from a proximal end portion (62) of the coil arrangement (22) to a distal end portion (63) of the coil arrangement (22), wherein the plunger stop(20) has a cylindrical section (27) which projects from the distal end portion (63) axially into the coil interior (25), and wherein the plunger (21) is arranged axially opposite the cylindrical section (27) of the plunger stop(20) and, in the active position (AS)of the pinion (7), protrudes from the proximal end portion (62) axially into the coil interior (25) of the coil arrangement (22). Reduced wear of the pinion (7) and/or the gearwheel (3) can be realized by extending the cylindrical section (27) of the plunger stop (20) into the coil interior (25) such that a face end (33) of the cylindrical section (27) is in the area of the proximal end portion (62).
