Starter

A starter comprising:

• a motor unit configured to generate a rotational force by supplying electricity;
• a subassembly comprising:
• a drive shaft configured to receive the rotational force of the motor unit and rotate,
• wherein the drive shaft includes an externally splined component which is received by the motor unit;
• and
• wherein the motor unit includes an internally splined receiving component which is received by the externally splined component of the drive shaft;
• a transmission gear slidably installed on the drive shaft;
• and
• a clutch mechanism installed between the transmission gear and the motor unit and configured to transmit or block a rotational force of the drive shaft to the transmission gear;
• an idle shaft extending in a direction parallel to the drive shaft, rotatable around a central axis of the idle shaft, and configured to be slidable in an axial direction of the central axial interlocking with the transmission gear;
• an idle gear installed on a first end side in the axial direction of the idle shaft and configured to mesh with the transmission gear;
• a driving gear installed on the second end side in the axial direction of the idle shaft and configured to mesh with a ring gear of an engine;
• a gear cover section configured to rotatably support one end of the drive shaft and a portion of the idle shaft and accommodate the transmission gear and the idle gear;
• and
• a bracket section installed between the motor unit and the gear cover section and configured to rotatably support a first end in the axial direction of the idle shaft, the bracket section including a through hole and a first opening section configured to accommodate at least a portion of the subassembly;
• wherein the through hole of the bracket section allows the other end of the drive shaft to be rotatably supported by the motor unit.
