摘要： An engine starter includes a motor having a tubular armature rotation shaft, and a rotation output shaft arranged on one axial end side of the motor coaxially therewith to be axially slidably supported. A clutch mechanism is included for transmitting torque from the armature rotation shaft to a rotation output shaft and an electromagnetic switch which has a shifting member to push the aforementioned rotation output shaft by an electromagnetic force in the axial direction to slidably move it. The switch also brings movable contacts in touch with fixed contacts to supply power to the aforementioned motor. A rear part of the rotation output shaft and the front part of the shifting member are inserted into the armature rotation shaft tube from opposite directions. The shifting member of the electromagnetic switch, the armature rotation shaft and the rotation output shaft are all coaxially arranged to reduce the length of the starter. The coaxial arrangement is highly effective in preventing invasion of dust into the contact chamber of the electromagnetic switch. To ensure a compact size for the starter a compact spring is provided for restoring the rotation shaft to a rest position after the engine has started.

摘要： An engine starter comprising a motor having a tubular armature rotation shaft, a rotation output shaft arranged on one axial end of the motor and on the coaxial line with the armature rotation shaft and axially slidably supported, a clutch mechanism for transmitting the turning force of the armature rotation shaft to the rotation output shaft and an electromagnetic switch which not only has a shifting member, by means of an electromagnetic force, to push the rotation output shaft in the axial direction to slidably move it, but which brings movable contacts in touch with fixed contacts, thereby to supply power to the motor. The rear part of the rotation output shaft and the front part of the shifting member inserted into the armature rotation shaft tube from opposite directions, the shifting member of the electromagnetic switch, armature rotation shaft and the rotation output shaft are coaxial. For making the whole length of the starter compact in coaxially arranging these parts, a composition preventing invasion of dust into the contact chamber of the electromagnetic switch is adapted. For providing such a compact composition, restrictions are made on the position of the spring as a means for restoring the rotation shaft to its former position after the engine has started.
