 present invention relates to an engine starter which starts an internal combustion engine by using an ultra-compact direct current motor, and more particularly to an electric engine starter which can remove a conventional recoil driving unit from its body and arrange a battery for driving the motor, outside there, hence to realize downsizing because of the most efficient arrangement of the components and to extremely decrease fatigues at each operation of various working machine.
2. Description of the Related Art
At the present, an engine starter which starts a compact air-cooled gasoline engine mounted on a popular portable machine such as a shearing machine and a chain saw generally includes a recoil driving unit, a follower connected to a crank shaft of an engine through an switching means such as a centrifugal clutch, and a shock absorbing/pressure accumulating unit including a spring, arranged between the driving unit and the follower for absorbing the driving power of the driving unit and accumulating the pressure under the follower. The recoil driving unit has a recoiling reel with a recoil rope wound there and a recoiling spring arranged between the recoiling reel and a casing, the internal and external ends of the recoiling spring being respectively fixed to the recoiling reel and the casing. The recoiling reel is rotated only in one direction by drawing the recoil rope, the recoiling spring is wound up to accumulate a spring power, and when the recoil rope is released in this state, the accumulated power of the recoiling spring is released to wind back the recoiling reel automatically.
The above recoil driving unit requires a drawing operation for drawing the recoil rope every time of starting the engine. The drawing operation of the recoil rope has to be done so quickly and widely that a person having little power or an elderly person cannot start the engine only by one drawing operation. Thus, there have been a lot of proposals to make the engine start easy through the drawing operation of the recoil rope and they are in a practical use, but the troublesome operation of the drawing operation itself still remains. On the other hand, a progress in the recent compact electric motor and battery is remarkable and in spite of being downsized, they come to have the larger capacity. Taking this situation into account, an electric engine starter is reviewed which can start an engine quickly and easily by a switching operation, in order to avoid the troublesome operationality of the above recoiling starter, and its development is desired.

 At the present, an engine starter which starts a compendious air - cool gasoline engine mounted on a popular portable car such as a shearing machine and a chain saw generally includes a recoil driving unit, a follower connected to a crank shaft of an engine through an switching means such as a centrifugal clutch, and a shock absorbing / pressure accumulating unit of measurement including a spring, arrange between the driving unit and the follower for absorbing the driving office of the drive unit and accumulating the atmospheric pressure under the follower. The recoil driving unit has a recoiling reel with a recoil rope wound there and a backfire spring arranged between the recoiling reel and a shell, the internal and external conclusion of the recoiling give being respectively fixed to the recoiling reel and the casing. The bounce reel is rotated only in one steering by drawing the recoil rope, the recoiling spring is wind up to accumulate a spring power, and when the recoil rope is released in this state of matter, the accumulated world power of the recoiling leap is released to wind back the recoiling reel automatically. 
 The above recoil drive unit ask a drawing operation for drawing the recoil rope every time of get down the engine. The drawing mathematical process of the recoil rope has to be dress so quickly and widely that a person have little power or an elderly person cannot start the engine merely by one lottery process. Thus, there have been a lot of proposals to make the engine start comfortable through the drawing operation of the recoil rope and they are in a practical use, but the troublesome operation of the drawing operation itself still remains. On the early hand, a progress in the recent compact electric motor and battery is remarkable and in spite of being downsize, they come to have the larger capacity. Taking this situation into score, an electric engine starter is review which can start an locomotive cursorily and easily by a switching operation, in club to avoid the troublesome operationality of the above recoiling starter, and its development is desired.
